Ham Radio Circuits and Repair / Reprogramming a Icon IC-745 ram board
« on: December 10, 2017, 03:43:20 PM »
This is a project I will be working on. There were several DOS base programmers made to read and write the content of the ram boards for the 745 and 751 radios.
The problem is they were all DOS base and used the computers printer port to send and receive data.

What I like to do is come up with a USB based programmer to do the same.

I will be adding lots of files and pictures to this thread over the next few days.

Hi,
Yes that should work as a under bond with no problem. Try and clean the board good, apply the cw25 and tape the trace down. Use a heat lamp to cure the epoxy and should be good to go. I did a video on this a while back.

So glad I found your video on youtube. Will watch it again and also the other videos on that topic.

I have an old Pro Reverb AA165 from my father in law and that makes a horrible sound when turned on. It was not in use for ages and I think I have to replace all the capacitors. Just have to get all of them.
It must be an older version of the amp from somewhere between 1965 and 1967. Serial number is A00252.
As I am not an expert on that topic, I hope to find some help in here.

Best regards from Austria

That pro is a nice amp.  First thing to do is get rid of that death capacitor and upgrade to a 3 wire power cord. Then start with the main filter caps. Also check that rectifier tube.  That will get her going in the right direction. We are here to help.
