Title: Strange characters on 706mkiig faceplate when TX'ing
Post by: n2teb on 2011-10-20, 04:12:08

When I'm using my 706mkiig remoterig setup on HF, on 80M (that's the only band I've noticed so far), when I'm transmitting, I see random characters come up on the 706 screen and sometimes the screen even flashes.  Any idea what is causing this?  Is it RF getting into the cable between the 706 radio and remoterig box?  If so, can I wrap a ferrite core around it to help?  Any other thoughts/suggestions?

Thanks!

Hi

It is probably RF going into the cable exactly as you asume. Under normal circumstances this is not a problem but if the RF field is very strong it can cause problem. The best is to keep the RF out of the schack with an RF-choke on the antenna feeder. A ferrit on the control cable may also help.

Hi,

also noticed that in the past. I've put some ferrite on the cable between RRC and TRX. Now everything is fine even when operating at high power.
