Gerber Files
This is a centralised index of Gerber Files which have been used for BATC and BATC Members' projects.
No responsibility is accepted for any errors, but they are listed here to promote home construction and experimentation.
Files should be uploaded as .zip files, and should also be referenced from another Wiki page describing the project.

G0MJW's Ryde board
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.
G0MJW's PD4 board
TBC (after CAT22)
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.

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.
G0MJW's HF3 relay board
Here's Mike's design for a SPDT relay PCB. The relay is General Purpose Relay, 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.

LNB bias tee and reference injection PCB
PCB Gerbers for the LNB Bias T and reference injection by Mike G0MJW in CQ-TV263 – or see BATC forum for more details: https://forum.batc.org.uk/viewtopic.php?f=15&t=3122&p=17416#p17343
M0RNW's G8TA Rx/Tx Changeover Controller Board
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.
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. Other components - see schematic.
