Author Topic: IC-1271A Ram Module Data  (Read 3051 times)

The ram module of the Icom IC-1271A does contain data which are lost as soon as the supply battery looses voltage. Of course it is possible to get the data rewritten by Icom. However, one could do that as well by oneself.
I am looking for the dataset which resides in the ram. I could locate those for other similar radios but not for the specific IC-1271A.
Can someone help?

Try contacting Roberto Nardo IK2RND. He sold the ram unit for a time (may still) and had all the data.

Thanks for that information. Actually I'll get a replacement unit from Roberto. The solution using an Prom is of course the best way. However, I'm still interested in the data because this allows to reprogram the unit after data loss.

Dieter -

This information was documented by Adam Farson, AB0OJ several years ago for Icom owners:

Hi Gregory,

many thanks for the helpful links.
The interesting thing is that I got a 1271 here with a Ram board that still works after more than 20 years without battery change.
