Subject: | Re: Dual Comm Transmitter Problem |
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.

Cool! Mine won't even twitch on VHF air! I guess the bandwidth is
too narrow on mine! Good luck!

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.

All,
Please excuse my intrusion but I was referred to your community for advice.
I own Yak-52 and am considering adding a Blue Mountain EFIS/LITE gen 4 to my
panel in favor of the current RMI. I need EHSI capability, which limits my
options but have had mixed advice on the blue mountain unit. Can anyone
impart some general knowledge, experiences, stories, etc?
Best Regards,
Scott Glaser
