Re: 6790/GM firmware for the Z80 version A6A2 ?
If Phill is making it all is good and it should work, I am the only one that knows all the software because I have all the master after RACAL gave them to me and I controlled them when I worked there, they dumped the whole HF line at the same time and went to Scope Shield Radios.

The 1600305 is software for RA6793A Thanks Gary for that list.? 1600305 was being offered by Phill for the Z80 version A6A2 board in one of his earlier adverts. I'll stick with my F8 board since that has the 1/10/100 Hz tuning steps firmware which I find much more friendly and pleasant to use. Regards, Dan

Michael Michael, the later versions of the A6A2 card indeed used a Z80 processor to replace the obsolete (by then) F8.? It completely imitated the original in function by order of the US military.? I have one in front of me. 73 - Dan

I have what I think is a 906 Squadcall. However, the circuit board layout is not the same, and the two power transistors attached to the side of the chassis are not there. There is not provision to fit these. Can anyone identify this radio please, or did Racal change the design part way into production.

I designed the front panel for the PRM4720B. I've never seen it referred to as a B2 though.

Re: Racal manpack models list
And excellent to see the PRM4051 on the home page. The first radio I worked on when I started at Mobilcal in 1979

Hi,
I hope you don't mind my unsolicited email but I have just had a look at your web site and noted you did not show a brochure for the Racal RA3711 HF receiver. I attach a scanned copy of the brochure for you if it is of any use? Not only do I have a copy of the brochure but I also have a RA3711 receiver. I also have somewhere copies of very old Racal Communications brochures dating back to the 1960's if they may be of interest?
Good web site by the way.
