Now the next step is to hack the firmware to enable RX below 100 KHZ.

I have done a LOT of reading on the 745 over the last year. There is a bit of code located in address 000 that contains the upper and lower band limits for 160 meters. At least on the R71 receiver which uses the same ram board. From what I read by shifting a "1" to the left by one place it will change the lower band limit.
Now that I can play write the board I can give this a shot and see. Worth a try.
A big thanks to HighPrecision and thumbs up to you
Again, Thanks for your words Buddy !
I wil add here the KiCAD files of the PCB and generated gerber files for production, please note that there is NO schematic in the project, only pcb.
Good year 2018 to ALL !
you know, you could replace the ram with a microcontroller and program it through usb?
Hello,
Thank you for your instruction and expertise.

As we can see the best way to keep warm is a workshop full of Hammarlund gear powered up in one corner whilst testing an Icom receiver to its limits on the bench. much more fun than turning up the heating.

1KHZ If you can do it, I'll get a battery for the ram module I have here and have you program it.

Cool, I am shooting for 0 starting frequency and see where it goes from there. May be tomorrow evening before I can go any further.
They say it will e a toasty 44 degrees tomorrow
I am going to get some more batteries and weld some leads onto them myself.
If all goes well this evening I will try the new file out.
So frigged cold here. Should warm up to mid 40s. Will be the first time out of freezing.
The file is already to be loaded into the ram board. We will see what it does. may record and upload.

I wish we had some of that out here.

It has not been this cold in a long time. It finally got out of freezing today. Upper 40's. By this coming Friday low 70's. Woohoo
