Thanks for the comments.

I do not experience any noise from the logic board as AG7C did.
Visual inspections shows that all capacitors are in place.
Getting to the other side of the board will require undoing of all nuts on the coax sockets.

Relays do not pick up by themselves, as the led's come up as well, indicating that issue is rather on the logic board.

I will try to grounding of logic board first and will see if it works.

General discussion forum / Antenna Switch 1289- RF issue
« on: 2014-12-22, 15:39:45 »
Hi,

I have just attempted to install an Antenna Switch 1289 at my remote location.
There was no issue to make a network connection etc.

When I attempted to use it on HF, at around 220 W out, there was an RF issue and some other relays in the switch started to pick up.

When tested on UHF, 2m FM, it had RF issues at 50 watts (few unselected relays picking up).

I tried to disconnect the network cable, place ferrite on supply, used different power supplies.

It seems to me that an issue is created directly on the antenna switch electronic board.

Anyone experience such an issue and was a cure found?

I am using two web switches 1216 with RAT pack and never had an issue with RF.
Actually until this unit was installed, I had no RF issues with remoterig gear.

Did you check what is the setting of AF on the radio, after start up?
For some reason, everytime I have started IC7100 via RRC micro, AF goes to zero so there is no audio.
I adjusted audio level on the radio, using HRD (or any radio control software) and all is fine here (using Vista).

Well, I did not get any replied but I know the answer to this question now.

RRC micro works well with IC7100. At first it seemed that I did not have any audio output from the radio coming through. But then using radio control software (HRD or TRX Manager) I noticed that AF sets at minimum each time radio starts from RRC micro.
So it is always necessary to set radio audio level as required.
Otherwise no issues so far

General discussion / RRC micro and IC7100

Hi,

 RRC micro can not power on IC706 so it can not be used in this combination.
 Can it power on IC7100?
 
 IC7100 can now be used with RRC1258.
 I suppose RRCmicro will work with it as well?
 
 Any idea or first experiences in this combinations?
