Transceiver’s box is starting to take a nice looking shape. After a long break with this project, these days I took some time drilling the front panel and adding all the buttons and connectors. The only thing left to do is the digital scale and the S-meter/PWR meter on the blank upper-right side of the image. This I will probably do in the next week or so.
On the inside I put all the pots and the two rotary switches, mode and band, on a PCB board with 6mm spacers to the front panel. It was the best solution for the button knobs to come out nicely on the panel.
For the digital scale I will use OM3CPH’s LED digital scale project. In the image below there are the 7 digits LED dispalys, a 9mm digit type, common anode. And for the S-meter/Power meter the schematic with LM3914 and a LED bargraph.
Also the “A” and “F” boards are almost completed. I found a factory made 9Mhz Crystal Filter (made by our defuncted ROMQUARTZ), togheter with side bands crystal. They are already mounted. Probably in the empty space there, for the CW filter, I will put a homemade 9Mhz filter with a bandwidht of about 500Hz.
The front-end board, “A412-A”, is about 95% done. I still have to mount 2 more coils for the band pass filter. They are already made, only the holes on the PCB are drilled weird, so I have to make them more large so the coil will fit.
