<p>G4KLB: Added schematic</p> <hr /> <div>For those of you who want to drive Microwave transverters from your Portsdown or need a higher drive level, the team have developed an 8-Band RF output switch that includes an RF amplifier. <br /> <br /> It is capable of amplifying the variable level from the Filter Modulator board / Lime SDR up to 10 dBm and switching it to separate external amplifiers for the 70, 144, 437, 1255 bands and up to 4 transverters for the higher bands. One of the 4 transverter output can also be used for 2300 / 2400 MHz - see mods below to maintain output level.<br /> <br /> The module should be used with the 8 band decoder which will provide PTT steering for the 8 bands - [[8-Band Decoder|see this page for more details.]]<br /> <br /> PCBs and the control PIC are available from the BATC Shop.<br /> <br /> The latest parts list is here [[:File:8_BAND_RF_SWITCH_V3.0_PARTS.xls]].<br /> <br /> Schematic is here [[:File:8 Band RF Switch V3-0.pdf]] <br /> <br /> ===Version 3 PCB - October 2021===<br /> <br /> We have seen a number of failures caused by the use of the 8 way switches with the LimeSDR (the PCB was originally designed for use with the Filter-Modulator Board). The problem with the LimeSDR is that it can easily deliver +17 dBm during its calibration pulse, thus feeding +22 dBm into the RF switch, which exceeds its absolute maximum rating at 146 and 437 MHz.<br /> <br /> The version PCB provides a solution by increasing the attenuation on the input to the 8-way RF switch, or to use a lower gain RF amplifier. The revised layout is as show:<br /> <br /> [[File:8 way switch v3.JPG|400px]]<br /> <br /> [[File:8 way switch v3 circuit.JPG|400px]]<br /> <br /> ===Version 2.2 PCBs===<br /> <br /> The circuit for Version 2.1 and 2.2 PCBs is here: [[Media:8 BAND RF SWITCH V2-1 SCH.pdf]].<br /> Note that the value of C13 should be increased to 2.2 uF to prevent the 5V regulator from oscillating.<br /> <br /> ===Version 2.1 PCBs===<br /> <br /> The previous version, V2.1 requires 2 minor corrections during construction. <br /> <br /> The grounded ends of R1 and R2 on the input attenuator need properly connecting to ground. Thanks to Colin G4EML for spotting this and pointing out that this can be corrected by scraping away some of the solder resist next to the pads and adding a blob of solder to connect the resistors to ground as shown in his picture here:<br /> <br /> [[File:V2.1 Rework.JPG|240px]]<br /> <br /> ====Lime SDR====<br /> <br /> When used with the Lime SDR, Dave G8GKQ recommended changes to the input attenutor in his article in CQ-TV 262 to improve performance at 2.4GHz. C16 changes to 1pF and R5 becomes a Zero Ohms link. The modification is shown here on a prototype PCB with the 1pf capacitor on the white square.<br /> <br /> [[File:6 8RF Mod.JPG|400px]]<br /> <br /> All the parts in the attenuator are 0603 sized; the V2.3 arrangement is in the revised parts list.<br /> <br /> Here is a V2.3 PCB for LimeSDR Mini use, and the underside showing the wire link. Assembled by David M0YDH<br /> <br /> [[File:20190201 182759-1008x756.jpg|400px]] [[File:20190201 182818-1008x756.jpg|480px]]<br /> <br /> ===Version 1 PCBs===<br /> <br /> [[File:8-Band RF Switch Built V1 small.jpg|576px]]<br /> <br /> The initial design was as shown above - the first batch of boards will be supplied in this form. The initial (V1.0) circuit is here: [[Media:8 BAND RF SWITCH V1-0 SCH.pdf]]. <br /> <br /> HOWEVER, the circuit needed some simple rework to provide a more stable power supply for the SKY MMIC and to equalise the levels across the bands. The modifications are to:<br /> <br /> # Cut the track on the underside between the output of the voltage regulator and the link point marked 5VA.<br /> # Replace the 7805 with a 7808 regulator (for 8 volts) and wire a 30 ohm resistor between the regulator output and the the point marked 5VB. Note that the resistor will need to dissipate 300mW (it passes 100mA), so 3 1/8 watt 10 ohm resistors in series might be easiest.<br /> # Wire a new 78L05 regulator on the underside of the board with its input from the 12V supply and its output to the point marked 5VA.<br /> # The input attenuator should be set up with R1=R2=68 ohms, and R3=220 ohms. To get the full 10 dBm output on 1255 MHz, add a series combination of 68 ohms and 2.7 pf across R3. The first batch of PCBs do not have pads for the extra capacitor and resistor.<br /> <br /> The modified board is shown below.<br /> <br /> [[File:8-Way RF Prototype Small.jpg|556px]]</div>

The headers are Molex KK254 or equivalent, you only need to fit them if you plan to use them. The PI GPIO header socket is on the bottom of the board, take care not to fit it on the top by mistake! There are two PSU options, only one is needed. The small MCP1584 DC-DC module, as used in the Minitiouner, is probably the easiest to obtain, if you fit this there is no need for the voltage programming resistors R1, R2 and R3 which are needed with the alternative Murata module - see the schematic. Needless to say, the MCP1584 module pot has to be set for 5V before connecting the PI. The reverse protection diode can be almost anything that will survive until the 1.5A PTC fuse activates. I got my PCB mounting DB25 from AliExpress, but they are available from major suppliers. The dimensions vary between suppliers, so be sure to check the PCB footprint for the one you choose.

<p>G4KLB: /* PE43703 Attenuator Controller */</p> <hr /> <div>This is a centralised index of Gerber Files which have been used for BATC and BATC Members' projects.<br /> <br /> No responsibility is accepted for any errors, but they are listed here to promote home construction and experimentation.<br /> <br /> Files should be uploaded as .zip files, and should also be referenced from another Wiki page describing the project.<br /> <br /> ===Ryde Front Panel===<br /> <br /> The Ryde Front Panel Push Button PCB as descried here: [[Ryde_Hardware#Ryde_front_panel]]<br /> <br /> [[File:Gerbers.zip|thumb|Ryde Front Panel PCBGerbers]]<br /> <br /> ===ADF4351 PIC Controller===<br /> <br /> The ADF4351 PIC Controller described here: [[ADF435x_PIC]]<br /> <br /> [[:File:adf435x.zip]]<br /> <br /> ===DATV Repeater Audio Switch===<br /> <br /> The DATV Repeater Audio Switch as described here [[DATV_repeater_audio_switch]]<br /> <br /> [[:File:REPEATER I2C AUDIO SWITCH V2022.zip]]<br /> <br /> ===G0MJW's Ryde board===<br /> <br /> This is like a plug in board for the PI4 that provides the 5V PSU, a cooling option and Ryde IO interface. The information is all below. There are two PSU options, only one is required. All fairly simple. These Gerbers are set up for JLC PCB. In theory all you need to do is upload the zip file with the gerbers and select quantity, solder mask colour and postage options. The BOM is an HTML file in the ibom zip.<br /> <br /> [[:File:RydeGpioV2.zip]]<br /> <br /> [[File:RYDE GPIO 3D.jpg|500px]]<br /> <br /> [[File:RydeV2Schematic.jpg|500px]]<br /> <br /> [[:File:ibom.zip]]<br /> <br /> ===G0MJW's PD4 board===<br /> <br /> TBC (after CAT22)<br /> <br /> This is a PCB to implement a Portsdown 4 with 25 pid connector for interfacing to test equipment and a PTT transistor that can switch light loads. There are also headers for the Langstone. <br /> <br /> [[File:P4GPIO2.jpg|500px]]<br /> <br /> Schematic [[:File:P4GPIO.pdf]]<br /> <br /> Gerbers [[:File:P4GPIO25Way.zip]]<br /> <br /> BOM [[:File:ibom25way.zip]]<br /> <br /> Sorry there is no parts list for Farnell, etc because the parts they supply just change too often, see the BOM for inspiration. The resistors and capacitors are mostly standard 0805 SMD, there are two through hole 100uF 16V electrolytics, non critical as long as they fit and you may want to fit a larger 2512 SMD resistor in the fan supply to slow it down if too loud. The headers are Molex KK254 or equivalent, you only need to fit them if you plan to use them. The PI GPIO header socket is on the bottom of the board, take care not to fit it on the top by mistake! There are two PSU options, only one is needed. The small MCP1584 DC-DC module, as used in the Minitiouner, is probably the easiest to obtain, if you fit this there is no need for the voltage programming resistors R1, R2 and R3 which are needed with the alternative Murata module - see the schematic. Needless to say, the MCP1584 module pot has to be set for 5V before connecting the PI. The reverse protection diode can be almost anything that will survive until the 1.5A PTC fuse activates. I got my PCB mounting DB25 from AliExpress, but they are available from major suppliers. The dimensions vary between suppliers, so be sure to check the PCB footprint for the one you choose. The right one is fairly short and should be flush with the PI USB/Ethernet when you out it in a box.<br /> <br /> ===G0MJW's HF3 relay board===<br /> Here's Mike's design for a SPDT relay PCB. The relay is General Purpose Relay, [https://uk.farnell.com/axicom-te-connectivity/hf3-56/relay-spdt-220vac-2a/dp/9913599 HF3 Series, High Frequency, Non Latching, SPDT, 12 VDC, 2 A]. Part number is dependant on the voltage in use in circuit. A surface mount diode e.g 1N4148 type, Molex KK connector and 3 SMA to PCB unions complete the build.<br /> <br /> [[File:HF3_Relay_board.JPG|250px]]<br /> <br /> Gerbers [[:File:HF3_relay_board_gerbers.zip]]<br /> <br /> ===LNB bias tee and reference injection PCB===<br /> <br /> PCB Gerbers for the LNB Bias T and reference injection by Mike G0MJW in CQ-TV263 – or see BATC forum for more details: <br /> https://forum.batc.org.uk/viewtopic.php?f=15&amp;t=3122&amp;p=17416#p17343<br /> <br /> [[File:bias.PNG|400px]]<br /> <br /> [[:File:BiasTGerbers.zip]]<br /> <br /> ===M0RNW's G8TA Rx/Tx Changeover Controller Board===<br /> This is v1 designed for a latching relay of up to 6 into 1 ports using an Arduino Nano. Hopefully it features in CQ-TV-279. PCB is intended for rail mounting in a 3U cabinet.<br /> <br /> Three SN754410NE H bridge driver ICs are used. The DC-DC boost converters are XL4005 type boards off EBay. U2 can be omitted - it's for an 18V supply to an LNB.

The information is all below. There are two PSU options, only one is required. All fairly simple. These Gerbers are set up for JLC PCB. In theory all you need to do is upload the zip file with the gerbers and select quantity, solder mask colour and postage options. The BOM is an HTML file in the ibom zip.<br /> <br /> [[:File:RydeGpioV2.zip]]<br /> <br /> [[File:RYDE GPIO 3D.jpg|500px]]<br /> <br /> [[File:RydeV2Schematic.jpg|500px]]<br /> <br /> [[:File:ibom.zip]]<br /> <br /> ===G0MJW's PD4 board===<br /> <br /> TBC (after CAT22)<br /> <br /> This is a PCB to implement a Portsdown 4 with 25 pid connector for interfacing to test equipment and a PTT transistor that can switch light loads. There are also headers for the Langstone. <br /> <br /> [[File:P4GPIO2.jpg|500px]]<br /> <br /> Schematic [[:File:P4GPIO.pdf]]<br /> <br /> Gerbers [[:File:P4GPIO25Way.zip]]<br /> <br /> BOM [[:File:ibom25way.zip]]<br /> <br /> Sorry there is no parts list for Farnell, etc because the parts they supply just change too often, see the BOM for inspiration. The resistors and capacitors are mostly standard 0805 SMD, there are two through hole 100uF 16V electrolytics, non critical as long as they fit and you may want to fit a larger 2512 SMD resistor in the fan supply to slow it down if too loud. The headers are Molex KK254 or equivalent, you only need to fit them if you plan to use them. The PI GPIO header socket is on the bottom of the board, take care not to fit it on the top by mistake! There are two PSU options, only one is needed. The small MCP1584 DC-DC module, as used in the Minitiouner, is probably the easiest to obtain, if you fit this there is no need for the voltage programming resistors R1, R2 and R3 which are needed with the alternative Murata module - see the schematic. Needless to say, the MCP1584 module pot has to be set for 5V before connecting the PI. The reverse protection diode can be almost anything that will survive until the 1.5A PTC fuse activates. I got my PCB mounting DB25 from AliExpress, but they are available from major suppliers. The dimensions vary between suppliers, so be sure to check the PCB footprint for the one you choose. The right one is fairly short and should be flush with the PI USB/Ethernet when you out it in a box.<br /> <br /> ===G0MJW's HF3 relay board===<br /> Here's Mike's design for a SPDT relay PCB.

<p>G4KLB: </p> <hr /> <div>The MacGuffin project is a collection of tools used to create an automated multi-band ATV system based on the Portsdown transmitter and the Ryde receiver. An RF path from the Portsdown or the Ryde to an antenna is created by using relays to select the appropriate intermediate equipment. This includes RX preamps, TX drivers and power amplifiers. Transverters may also be a part of the system.<br /> <br /> The system automatically connects the components for the band selected by the Portsdown and sequences the transitions between RX and TX. An Arduino Nano and MCP23017 IO expanders are used to generate control signals. They operate the relays used to select the RF paths connecting the components for the various bands. PTT and DC power to the amplifiers is also controlled.<br /> <br /> ===PCBs===<br /> <br /> PCBs have been designed for the Nano and the MCP23017. The Nano board has circuitry to interface with the Portsdown and other equipment. The IO expander board is designed to easily connect to a 16 relay module from eBay or to user-selected relays through optional drivers or logic level signals. A builder could choose to use modules from eBay instead of the MacGuffin PCBs.<br /> <br /> ===Configurations===<br /> <br /> There is no standard MacGuffin configuration as it is expected that each builder will be using parts in hand or the parts that are available at the time they are building. The documentation does include examples of various possible configurations and a list a RF relays available at the time the design was started.<br /> <br /> The first step in designing the system is to decide which bands will be used. That starts with the setup of the Portsdown. Next a relay configuration can be planned which will switch the RF through the appropriate equipment for each band. Then a basic Arduino sketch is modified to match the builder’s Portsdown configuration and the relay configuration. Modifying the Nano application does not require knowledge of the Arduino programming language. Tables in the sketch determine the control of the relay paths and the text displayed on the LCD.<br /> <br /> This block diagram shows the basic structure of a MacGuffin system.<br /> <br /> [[File:block diagram McGuffin.png|1200px]]<br /> <br /> <br /> ===Files below are contained in these zip files.===<br /> [[File:MacGuffin Arduino files.zip]]<br /> <br /> [[File:MacGuffin Main files.zip]]<br /> <br /> ===Educational material===<br /> <br /> These documents describe different aspects of the MacGuffin system.

<p>G4KLB: </p> <hr /> <div>The MacGuffin project is a collection of tools used to create an automated multi-band ATV system based on the Portsdown transmitter and the Ryde receiver. An RF path from the Portsdown or the Ryde to an antenna is created by using relays to select the appropriate intermediate equipment. This includes RX preamps, TX drivers and power amplifiers. Transverters may also be a part of the system.<br /> <br /> The system automatically connects the components for the band selected by the Portsdown and sequences the transitions between RX and TX. An Arduino Nano and MCP23017 IO expanders are used to generate control signals. They operate the relays used to select the RF paths connecting the components for the various bands. PTT and DC power to the amplifiers is also controlled.<br /> <br /> ===PCBs===<br /> <br /> PCBs have been designed for the Nano and the MCP23017. The Nano board has circuitry to interface with the Portsdown and other equipment. The IO expander board is designed to easily connect to a 16 relay module from eBay or to user-selected relays through optional drivers or logic level signals. A builder could choose to use modules from eBay instead of the MacGuffin PCBs.<br /> <br /> ===Configurations===<br /> <br /> There is no standard MacGuffin configuration as it is expected that each builder will be using parts in hand or the parts that are available at the time they are building. The documentation does include examples of various possible configurations and a list a RF relays available at the time the design was started.<br /> <br /> The first step in designing the system is to decide which bands will be used. That starts with the setup of the Portsdown. Next a relay configuration can be planned which will switch the RF through the appropriate equipment for each band. Then a basic Arduino sketch is modified to match the builder’s Portsdown configuration and the relay configuration.

<p>G4KLB: </p> <hr /> <div>The MacGuffin project is a collection of tools used to create an automated multi-band ATV system based on the Portsdown transmitter and the Ryde receiver. An RF path from the Portsdown or the Ryde to an antenna is created by using relays to select the appropriate intermediate equipment. This includes RX preamps, TX drivers and power amplifiers. Transverters may also be a part of the system.<br /> <br /> The system automatically connects the components for the band selected by the Portsdown and sequences the transitions between RX and TX. An Arduino Nano and MCP23017 IO expanders are used to generate control signals. They operate the relays used to select the RF paths connecting the components for the various bands. PTT and DC power to the amplifiers is also controlled.<br /> <br /> ===PCBs===<br /> <br /> PCBs have been designed for the Nano and the MCP23017. The Nano board has circuitry to interface with the Portsdown and other equipment. The IO expander board is designed to easily connect to a 16 relay module from eBay or to user-selected relays through optional drivers or logic level signals. A builder could choose to use modules from eBay instead of the MacGuffin PCBs.<br /> <br /> ===Configurations===<br /> <br /> There is no standard MacGuffin configuration as it is expected that each builder will be using parts in hand or the parts that are available at the time they are building. The documentation does include examples of various possible configurations and a list a RF relays available at the time the design was started.<br /> <br /> The first step in designing the system is to decide which bands will be used. That starts with the setup of the Portsdown. Next a relay configuration can be planned which will switch the RF through the appropriate equipment for each band. Then a basic Arduino sketch is modified to match the builder’s Portsdown configuration and the relay configuration. Modifying the Nano application does not require knowledge of the Arduino programming language.
