Finally got my ubitx on the air!

Just finished building the ubitx V3 that I have had for a while (Photo attached)
I am using the KD8CEC software and the stock 2 line display.
Power chain mods completed, 14 Watts on the lower bands now, dropping to 5 Watts on 10m
The ND6T AGC and S meter were a very worthwhile addition.
I have also added a VOGAD mike preamp using the SL6270 and an old dynamic microphone from my Alinco DX70.
First few contacts on 40m have been very encouraging.

Excellent for the VOGAD, you can just whisper and have QSO! I Believe I have a spare Plessey like u used, which circuit have u used? I would be pleased to replicate it!

I used the circuit straight out of the datasheet, using the 12V TX line for power and a 78l05 regulator. My circuit is attached.

Excellent! If I have the same part I will follow this schematics. That part is very military and sounds very good on air.

I found it, a Plessey SL6270C. Thanks very very much for the schematics with the indication of the easy mod to do on the ubitx. It will make it in the next weekends.
