Purchased a M5Stack-Core2 module and loaded the free software from Armel Fuaveau, F4HWN. In addition to the nice meter function it has a transverter offset so you can see the effective frequency - it connects to the Icom IC-705 via bluetooth.

Collins R-392
A few months back I picked up a nice R-392 - had to get a 28v power supply. The radio works well and has the solid-state audio module in it.

OZ2M Beacon Keyer
5 August 2023 - Placed JCLPCB order to version 11.
23 June 2024 - New version 1.1
8 June 2024 - Just sent the v1.0 Gerbers off to JCLPCB.
27 May 2024 - Prototype working!
Finally got the PIC programmed - had one bad chip and the key was to use PGD/PGC pull-up in the IPE on both and changing the program to use an XC oscillator type. Here's the prototype board working.
25 May 2024 - Progress so far.
Designed the board using the schematic from OZ2M's website. Sent the boards off to JCLPCB and received them Thursday and received the PIC 16F84 chips yesterday. Worked on the first board yesterday and still have some components to put on it. Programmed the PIC this morning. Here's what the boards look like from the JCLPCB website.
Here's the schematic. I only used the PTT and KEY1. I also did not use the programming circuit.
