My EDS-10 arrives this week, probably tomorrow. Saturday I did hook the radio up to my ancient Arrow antenna and took a listen to AO-27. Receiving on the subband as I would if working the satellite, one thing odd I noticed was the off frequency response of the radio. If I was 5 kHz off, it seemed that very little could be heard. Most of my other radios give more of a partially readable signal when off frequency. Sensitivity was excellent. I also listened on the triband Diamond rubber duck I purchased to replace the stock duck, and reception was still decent.
I'll agree the manual is horrid, but there is a note included that says it is a preliminary version and an updated one will be posted to the website soon. More to follow after the headphone adapter arrives. 73, Drew KO4MA ----- Original Message ----- From: "Patrick STODDARD (WD9EWK/VA7EWK)" <[email protected]> To: <[email protected]> Sent: Tuesday, May 26, 2009 1:21 AM Subject: [amsat-bb] DJ-G7T and full-duplex satellite operating > > Hi! > > I spent this afternoon using my new DJ-G7T HT on a few passes, with > mixed results.
