One of these radios found a home at my house yesterday. I am typically a collector / restorer of tube based radios, but have had a couple Harris RF-590's and a Watkins Johnson. I am familiar with

Jeff, I have replied direct via this group and via email. I've tried a few times so no idea what is happening. Perhaps I am being dumped as spam. Can I use the mobile number that ends in '030' to

HI RIchard. No i've not heard anything from you since i asked you to contact me direct. Jeff G8XXI

Are there members who can help me with hex eprom files for a racal ra1792? I am looking for versions that have the 1Hz readout and when possible with the ieee488 gpib interface .

Jeff, Did you receive the email with my contact details? I am still very interested in acquiring a set of these rails. Richard G7RVH

I run a 6790GM and it shares input through a Racal antenna tuner that front end bandwidth limits to a 1 MHz slice of HF bandwidth, determined by slave to a RA 6217E. This feeds a 8 port Nuvistor

Dave, Many thanks for your clear and informative response. I now understand what is going on with the Syncal 2000 / VIU / 540G combination that I have. Also, the information regarding the other C &

Hi Richard The momentary break method does not store any data, each time it is initiated it resets the microprocessor and completes an active tune cycle with RF to match the antenna as best it

Have a look at sema4radios dot com

Dave, Thanks for your response. Just to be clear when using the momentary break method no data is stored. Tuning data is only stored when using the PWM method. Is this data still stored when the

Graham,? I dont use groups.io so much, so I ask a stupid question. How can I use graham_douglas@.... ?

There are two distinct tune modes with the BCC540G The first one is the standard initiate tune by momentarily breaking and restoring the DC supply on Pin C and then applying at least 1w of RF the

Hi all, I am contemplating purchasing a Syncal 2000 VIU to set up my Syncal 2000 in my land rover. However, there is no point in buying it if I can't acquire the rails to mount it. If anyone has a
