[amsat-bb] AO-92 L/V with an Alinco DJ-G7T full-duplex (long)

[Patrick STODDARD (WD9EWK/VA7EWK)]

Hi Rick!

I didn't look for the Comet equivalent diplexer when I had
HRO ship me the MX-37. Looking at the two, it seems like
it's a matter of tradeoffs in picking one over the other
(except for price - the Comet diplexer is $10 more at HRO -
and not clearly in stock at any of those stores). You get
lower insertion loss with the Comet, but better isolation
between the band ports with the Diamond.

Alinco's EDS-14 had been more widely available for a while,
but now it looks like it has been replaced by the EDS-10.
The manager at the Phoenix HRO store was the one that told
me about the Yaesu CT-91 speaker/mic adapter working with
the DJ-G7T, which I confirmed for myself. Alinco's web site
still shows both the EDS-10 and EDS-14 as "plug conversion
cables" to take the speaker/mic jack and split out separate
jacks for the speaker and microphone, where the latest PDF
version of the owner's manual allocates an entire page to
the EDS-14 and doesn't mention the EDS-10.

Do you have a 1.2 GHz antenna of some sort? There are
WA5VJB designs for that band, a Comet antenna sold at HRO
and other stores, and a couple of Yagis available on eBay
(among other options). There's at least 3 of us who work
AO-92 L/V from the DM43 side of metro Phoenix (you can
also hear K7TAB and N7NEV on AO-92 L/V). Other than two
weeks ago when K7YDL was on from DM33, there hasn't been
regular L/V activity from your side of the city. Join us!

Hope to hear you soon on AO-92 L/V. 73!
