Icom 701 and computer control

[VE7DCW]

I picked up an old Icom 701 locally and after doing some internet research I found that it was possible to mod this radio to allow computer control of some radio functions through the back panel ACC plug despite the fact this is a pre-CAT transciever! (rig manufactured c.1980)

I know that computer control is possible because my searches led me to a Youtube video done by KA6BFB demonstrating an I-701 controlled with Ham Radio Deluxe of all things!

I'm really intrigued to experiment with the possibility of doing this with this old rig that supposedly can't be supported with any kind of computer control.Any information anyone can supply would be greatly appreciated :)

Take a look at the processor unit used in the R-70 and the IC-720(A) - is it the same as the '701?

If so...I know how to make it work.

Fred .... the information i've been able to glean on my searches indicate that the mod for the icom 701 is similar to mods... "that can be performed on the Icom 211 and and the Icom 245 as the use similar systems and pinouts on the ACC socket..." it's not much to go on but KA6BFB claims he was able to do it.... i've yet to dive into this 701 under the cover yet,as I wanted to DL the manual for thing and get an idea of the inner workings before I go into it...... it's a 30 year old radio but it performs quite well ...... i've never owned or really operated an icom radio so i'm not familiar with it........ but for some strange reason curiousity has me attracted to this radio ........ this coming from a Yaesu guy!

Seems pretty self explanatory to me OM. :twisted:

It's insanity I tell you ....... :wiggle:

I dunno. Take a slow glance around the Island. Do you notice that insanity IS the Islands' version of sanity?


Oh shit. What have I done? Carlo is going to be along shortly, and let me know he resembles that remark, then I'll have to stand erected...your right it is insanity.................Never mind.

Have you asked Dave KA6BFB? Here is his email: dave@tinkyr.com and his webpage: http://www.qsl.net/ka6bfb/

Seems like an interesting guy.

Excellent ....i've fired off an e-mail to Dave asking if he can provide any more info on this 701 control mod than he provided in his Youtube video .....this looks to be a cool thing to attempt on this old icom radio!

Hi there..

I have tried to post three times now, so forgive me if there is a multiple post. I have just completed my webpage for the newest Icom interface project. I have successfully interfaced a 211, and the 701 is the same protocol except it also requires an analog voltage for switching. I have made accomodations for this in my new design. I have not tested a 701 yet because i don't have one in my possession. If you want to check out the webpage, it is at http://home.comcast.net/~tinkyr/radi...0Interface.htm There is also a link to my youtube site so you can see videos of the interface working. This has been a lot of work, and if you have interface questions about these radios, i will be happy to share what i have uncovered.

Hey Dave!
Welcome to the Island! Go put you feet up on the beach and enjoy. The bartender will be along shortly.

It is nice to see folks like who are willing to share their knowledge. I personally thank you for doing so.

Edit: ​OK, I just looked at your page and I have to say that I am impressed. Nice Job!
