Interesting discussion. Gives me an idea.
We'll soon be announcing
to the analysis. Hopefully others can add some
comments and analysis. A lot can be learned from kits when you go beyond
just assembly. Is it the same as designing a rig from scratch? No, not quite
the same thing. But being able to really analyze design gets one close to
being able to do design work.

Indeed, it was. Still seems the best answer to the question posed!

Wasn't that the answer Slarty
If you are operating split frequencies for transmit and receive, the a
second RX lets you listen to both frequencies at the same time.

to the utility. If that is done, then each frame will also have to have a
sequence number so the radio can recognize a duplicate frame it has already
ACKed that got lost. Alternately, a load address for the data would do it by
just overwriting the same place with the resent data.

often be
found at radio shack, perhaps at a bit higher voltage than the originals.
Here is some more general info on tha cause (at the end particularly):

Or search for bad capacitors.

A magnetic mount antenna would be used for mobile operation, and the car 12
V electrical system could supply power. I would start there and get to know
some local hams, join a club if there is one.

I sure would like to more understand what was going on!

circuits can hum on signals but I think the effect is for a reason different
from picking up 60 Hz on the antenna.

for rig or antenna and get on the
air and see what you can work. Not just one CQ and giving up but gining it a
good try as time permits.

Hi John,
You might want to look into closed captioning software. Also look at what is
built into windows to do speech to text conversion --- its in the ease of
access folder in accessories folder.
