QMX firmware 1_00_017 AGC and S-meter demo

QMX multi-band multi-mode portable transceiver: qrp-labs.com/qmx
In this video I demonstrate the action of the new AGC and S-meter features in firmware 1_00_017. For testing I generated an S9+30 (huge) signal using another nearby transceiver (PA disconnected, internal Synth active only). Without AGC the audio output of QMX is heavily overloaded and clips, generating distortion and some pain if you had earphones on. With AGC, the huge signal is reduced to about S9 level, comfortable and undistorted.
AGC action is applied to a short delay line with as little as 1.5ms latency, so the action is instant, there is no short period where high audio levels make it through to the output.

Hopeful for ssb in the future, thanks for continued product support!!!

Very nice that you show the AGC action in dB. (AA4HA)

Is getting better all the time. Once the mid band version is available I will order one.

Great Hans. I'm having a lot of fun with the QMX. And ACG and S-meter is a big plus. All working as it should. Kudos!

[@SuperSuperGenius]

Excellent! Mine just arrived with Rev 14 firmware. I am looking forward to the update!

Awesome updates! Can't wait to get my assembled QMX. Just ordered it yesterday, so I will have a while to wait, but looking forward to getting it.

Wishlist: an integrated or add-on mini-ATU for the QMX.

Hey, I can't find it anymore but in a video I've seen you mentioned there would be a QMX 60 -> 15 and I was wondering if that'll be a thing or not? or if it's worth holding out for it? I'll be buying the 80-20 otherwise but I never plan on using 80m, 15m on the other hand is very appealing ;) Thanks for everything you're doing, and looking forward to get my hands on one of these ;) Cheers VK4ALE

Hans, I knew you would get the AGC update done. I placed a assembled QMX order about two weeks ago, so I figure I may recieve it around November or December time frame, which I do not mind waiting. You produce a fantastic product. Thank you for your email instructing on how to open up the qcx mini and soldering in a jumper for the battery indicator to work. Got that done on all three of my Mini's. N7KO Ken

When will we be seeing SSB? I know you are hard at work, and it's coming, but an update on it would be awesome!

interesting stuff.... but please put your camera on a tripod or some sort of other stand when filming
