Ham Radio Circuits and Repair / Reprogramming a Icon IC-745 ram board
« Last post by Radio Tech 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.

This video was very helpful. It had exactly what I needed to see and the commentary was also helpful.

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.

Just got a "working" V-7a and found a few things inside that may need to be addressed . the bulb that is mounted on the top , the trace has separated almost to the point of the bulb socket coming off. can I use that CW25 epoxy to secure this before it breaks free? in the pic I have put a small sheet of paper to show the depth of the separation . does this cw25 need to be clamped until the cure time is up?

well Im hooked...after the sb614 station monitor I purchased and recapped I am looking to get some equipment to check and learn how to do a basic Alignment   ...the next addition is a PC USB 2CH 60M 200MS/s Digital Oscilloscope 60M Spectrum analyzer Data Recorder , as well as a DANIU FY3224S (FY3200S-24M) 24MHz Dual-channel Arbitrary Waveform DDS Function Signal Generator Sine Square Wave Sweep Counter, VICTOR VC3165 110V-220V Professional Precision Frequency Counter Meter. also got a cheap cobra 19 plus . to do these tests on. I need to get some kind of an attenuator ? are these a good start? cheap ya...
point me toward some reading material that covers old school  Alignments and tools? Did I go too fast here in my equipment? as far as the 11 meter band will that FY3224S work in this application.  thanks
