Well, never mind about buying one of your boards. I found the schematics and files on your web page. Plenty of information to build my own - thank you!
This is brilliant. Just tonight I got a very good deal on an Icom IC-720A, which is going to be my only base HF rig for a little while. This is a great hack, I love it!
If you happen to get that board built, let me know. I'd love to buy one :)
Actually in 1980, the IBM PC was still in design stage ! It was not introduced to marketplace until 1982. In 1980, the 8-bit processors (6502, Z-80) were common and the operating system was: Digital Research CP/M.
Sadly, I lived the history -- and people are already forgetting :-(
@w9gb The IBM 5150 came out in August of 1981. I actually had one that I bought used and used it until 1994 for some DOS stuff I was doing. It ended life with a high velocity .308 bullet from my rifle. It had a 10MB hard drive and two floppies, a parallel port and a serial port. I also designed a card to interface to the ISA port in that thing and put out a 1 Mbps serial stream on a 10 wire bus I cam up with using RS-422. That thing used over 30 chips to do what can now be done with one USB IC
@w9gb Yes I do realize that, that is why I mentioned that I would need a budget. I would be emulating a radio like I do now, and using a DDS to create the signals
Tinkyr you rock!

The board artwork is available. It's all on the website. home.comcast.net/~tinkyr/radio/projects/720_to%20HRD/720A_to_HRD.htm

W9GB, yes, I know. I built my HW-8 back in 1975. I was just toying with my good friend KA6BFB.

Great job once again...Can you get HRD to control my HW-8?

@n6vmo Hi John.. I sure could do this for an HW-8 if I had enough of a budget!!!

@n6vmo You do understand that the Heathkit HW-8 is an ANALOG QRP transceiver ??
There is NO uProcessor to control or CAT interface (since there is no uProcessor to control).
The HW-8 came out in mid-1970s, when the Intel 4004, 8008 and Motorola 6502 were brand new processors.

Hi TinkTron,
I just got one of these radios after watching your video, but where can I find the schematics of the interface?
