I just subscribed to the group this evening; my name is Terry Young, call sign n0ve
I'm looking for help with a problem. I've had my IC-7000 since 2011 and an AH-4 since 2012. For about the past three and half years the 7000 has been used once or twice a year for UHF/VHF only and the AH-4 hasn't been used. About a week ago I reinstalled the 7000 & over the past couple of days I reinstalled the AH-4 along with a new Chameleon EMCOMM II. The EMCOMM II is a 60 foot wire antenna that covers 6M to 160 M, the manufacturer recommends a 50 to 55 foot counterpoise, and an external tuner is required. I installed a 58 foot counterpoise figuring I would put an analyzer on it and trim it back until I got an acceptable SWR reading.
Since reinstalling the 7000 I have participated in a couple of UHF/VHF nets with no problems; the most recent net being last Sunday evening.
When I finished installing the antenna this morning I connected an antenna analyzer though the AH-4 with unsuccessful results. On 7.240 MHz I got back a reading of infinate SWR. So, dialed in the High Noon Net (7.240 MHz) and just listening worked fine. I turned on the tuner - no problems. When I pressed the push-to-talk button/lever the radio shut off and immediately restarted. I turned the power down to 75% and again, when I pressed push-to-talk same results. I disconnected the HF antenna and the tuner cable and tried a UHF frequency (70cm) with the same results. Before anyone asks, befoe I proceeded with the antenna installation I verifyed the AH-4 us compatible with a long-wire antenna and after the problem I did verify I have the UHF/VHF plugged into Ant-2 and the HF antenna plugged into Ant-1.
Will an antenna analyzer not work going though the AH-4? Has anyone experienced this problem? What did you find the solution to be? Or, any thoughts on what the problem might be?
