Hi Mike,
Thanks for the feedback. Will see what might be charging around the house
here as a starting point.

My experience is that is the pattern of many battery chargers especially
when the battery is fully charged but still connected.
tnx

John,
Locating the source is usually faster than speculating as to what it might
be. Start with the usual - power the '706 with a battery supply and then
turn off power in the ENTIRE house when you are hearing the noise. If the
RFI goes away, the source is somewhere in your house and you can then
start re-applying power one circuit breaker at a time until the noise
returns. You then need to examine every device on that circuit.
If the RFI does not go away when you power down the house, then it is time
for action. You will need to take the '706 mobile or portable and start
traveling around the neighborhood, or even further. Incidentally, try
using the rig in AM mode to see if you can hear the RFI better than with
SSB. Keep us posted on how it goes.

I have an RFI problem that mostly shows up during the day, and affects
most
bands, although I notice it most on 15 and 12 meters as I am on those
bands
more during the day. It is a buzzing type noise that comes in around S6
or
so on my Icom 706MKII, and the NB won't do anything about it. It doesn't
show up all of the time, but comes and goes, It seems to cycle with 4
seconds on and 3 seconds off, and sometimes will cycle quicker than that.
Anyone else seen an RFI issue like this and have any idea what it might
be?
It doesn't seem to occur at night.
