A few hours ago, Hans G0UPL released beta firmware that enables SSB operation for the QMX-series of transceivers.
Furthermore, Hans is "retiring" the QSX concept since the new fw for the QMX makes that project redundant.
From Hans:
This is the beta release page for the SSB firmware for QMX/QMX+ transceivers. This is a very complex project. The beta release here is provided without warranty, for brave beta testers who wish to try out the firmware and report back on any issues found or suggested enhancements. The firmware runs on both QMX and QMX+; for convenience from now on, this page will state "QMX" but that means equivalently QMX or QMX+ unless otherwise stated.
After a period of beta testing, the firmware will be published to the regular QMX page, and the regular QMX operating manual will be updated to reflect all the changes for SSB. Eventually I will publish extensive technical documentation describing the entire system in detail.
.
Please remember - this is beta firmware, for experimentation.

Nice, may try it tonight if I have the time. Had an early work start today, but have been looking forward to this release for a while. Great work, Hans! Thanks for the heads up, John!
ReplyDeleteHi Jim, there are already significant updates to problems in the initial firmware so I'm not in a rush just yet. But like you, I've been waiting a while - not much of a phone op here but the accomplishment by Hans is much appreciated.

807 miles with 1 W on 20 meters. Fun radio after calibration, which does take a while.
DeleteCongrats! My mic element arrives Monday - can't wait to try it out.
DeleteJohn,
ReplyDeleteHave you been able to test SSB yet?

Hi Jim - no, my mic element didn't come in till Monday...I'm planning on getting to to it this Saturday though. In the meantime, there are a few reports on the Group.io from others who have tried SSB with good results.
DeleteHow about you - have you tried it yet?

John,
DeleteI have been doing a decent amount of POTA hunting on 20 and 40 meters, no contacts yet on 10 meters. All good comments on audio.

I finally got the mic wired for the QMX+ and have listened to the audio on another receiver. It needs further adjustments and there are many to make. For now, it works and I did make two quick SSB contacts in CQ-WPX-SSB, both on 20 meters. But the transmitted audio is not soundingl like it should at this point. I will continue to monitor the Group.io and perhaps follow along with the successful settings posted by others. It will take some time to get things tuned in so that SSB sounds good on all bands.
