After the success of getting HRD to work with the Yaesu FT-736R as shown in another video, I thought I would try something totally ridiculous and see if I could do the same thing with a 31 year old radio. This one turned out to be quite a challenge

  • 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 :)

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

  • 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

  • Tinkyr you rock!

  • 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!

  • maybe you can make the interfaces and flogg um,oops i mean sell,jeff... m6glh

  • @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

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

  • @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.
