I need a few "beta testers" for an article I have written which explains 
all the details of a full-featured Quadra interface system for use with any 
transceiver whose operating frequency can be read by the logging computer. 
The article is complete and details how this is all accomplished. It will 
be published on the web as soon as it is "beta tested" for clarity.

If you would like to automate your Quadra, are presently using a logging 
computer in your station, and would be willing to give me your feedback 
after getting it all going, please contact me at [email protected] or 
[email protected] for access to the article rough draft.



Excerpts from the article:

Your Quadra can automatically change bands, change antenna ports, preset 
the antenna tuner, and power up/down following your ICOM/Kenwood/Whatever 
transceiver. .

The conventional interface recommended by Yaesu to use the Quadra with 
non-Yaesu transceivers is detailed in the Quadra manual and an ICOM 
implementation of it is described on Adam VA7OJ/AB4OJ's web page. This 
method does not include any provision for automatically changing 
bands/antennas/antenna tuning on the Quadra to follow the transceiver, or 
of automatically turning the Quadra On/Off with the transceiver.

My Quadra now comes on whenever I turn on my ICOM 756PRO, Follows it from 
band to band from 160 meters to 6 meters (all WARC bands included), and 
selects the appropriate antenna port just as if it was connected to a Yaesu 
transceiver....
