    I currently have two: WELZ swr and power meter type SP-220 1.8 TO 200Mhz covering power ranges up to 2, 20 and 200 watts, made in Tokyo Japan and bought as suitable for the 2 metre band. HANSEN SWR 50B which I have used regularly down to 118 Mhz and have no doubt will go further. It does not specify on the meter its frequency range and I have mislaid its instruction booklet but it was bought for the 2 metre band. Also made in Japan. These are the sort of meters that can be bought in ham shops and Radio Spares. If you look inside them they are broadly similar in design and there is nothing normally which would restrict them to a narrow bandwidth. Maybe yours works on a different principle. John From: KD4ZHA@aol.com Cool! Mine won't even twitch on VHF air! I guess the bandwidth is too narrow on mine! Good luck!

    --> Avionics-List message posted by: "John" <joplin1@charter.net> I want to thank all of you for your help. I think a VSWR check might be a good place to start. I am not sure how to locate a 'ham' radio operator in my area. I will give Radio Shack a call tomorrow. Maybe they can provide me with a good source. All of you have stressed the importance of good coax connectors and clean tight grounds where the antennas attach to the aircraft. That will be my next step. I will save the harness re-wire as a last resort. I have tried three different headsets ... the two SoftComm headsets that came with the aircraft and a LightSPEED QFRXCCc which I purchased in November. I made a few cell phone calls using the Aux Audio Input feature of the LightSPEED. I can receive the dial-up ASOS weather reports anywhere in the country loud and clear. Somehow, the cell phone antenna is strong enough to ring the number, but too weak to carry on a conversation. The answering party reports heavy static and broken transmissions. I hope my cell phone experiment didn't damage anything. I started having the radio problems about the same time I used the Aux Audio Input feature of the LightSPEED. It is going to take me awhile to do the trouble shooting, but I will report everything I learn it to the list. John

    Check the yellow pages for your local chapter of the ARRL, they are listed in mine, may be in yours as well. They can put you in touch with registered ham's.
