I recently purchased one of these radios and installed it in my 701.
This is an inexpensive unit that I purchased new from Aircraft Spruce.
Based on my many hours of operation with this radio (2 flights) I can
say that it works fine. On my first test (in the hanger) everything
seemed to work fine. However once I started the engine, the unit would
not quiet down even though the squelch was turned all of the way up.
After flying with it for a few minutes, I had to turn it off because it
was blasting my ears with noise. Once on the ground I looked at the
manual and found there was a programming change (easy to make once you
are aware of it) that would cure the problem. The second flight proved
everything works fine.

The biggest issue with it was creating all of the connections so I could
plug it into the back of the unit. The female connector required
soldering to the small pins of the connector #22 wire to each pin (no
they were not the crimp type). Of course the small soldering iron I had
at home was a little too large so it made the job of soldering more
difficult because you have to make sure not to bridge over to another
pin. I placed shrink tubing over each connection to make sure there
were no shorts.

Once the female plug connections were made, I had to make all of the
connections to power, ground and the headsets. Hindsight being 20-20, I
should have drawn locations to scale on a large piece of cardboard and
sized the lengths of wires needed for each of the terminals. That would
have made a much neater job and reduced the mass of wires I have running
underneath my dash.

The hardest part was soldering the connectors on the plug. I searched
the internet for information to help with this and came up with
nothing. Also, on this forum I have only noted references to people
buying cables already made, no one has actually written about
constructing the cable and connectors. Now that I have everything
working, I am sure there will be someone who will come up with ideas
that I could have used.

Anyway there was a question in the past about these radio's so I thought
I would offer my experience. Based on what I have found to date, if you
are looking for an inexpensive radio you might want to consider one of
these. If I have any problems with the radio in the future, I will send
a follow up post. Well any problems that are not self inflicted!

Hi Dan,

Thanks for that update. I too was concerned about the squelch
problem. Do you think what you did was a one-time fix or will you
have to reset the squelch often?
Thanks again,



Tommy Walker in Alabama





The term //mayday// used for signaling for help (after SOS), comes
from the French word //m'aidez//, which is pronounced "may day" and
means "Help Me."



Tommy: It was a simple fix. In their operations manual the change is

listed under _6.6 User setting_ "Automatic voice operation control gain
for intercom". There are four settings, HI, MID1, MID2 or LO. My radio
came with a HI setting and I changed it to LO which seems to work fine.

However, I have just started using this transceiver so I am far from
being an expert. I carry my hand held radio as a backup.
