Any reason not to replace the QLG1 battery with a supercap? -- Brent DeWitt, AB1LF Milford, MA

My rule of thumb is that 10dB power gain is the minimum amplifier gain worth bothering with. 73, Don N2VGU

Hans. I just placed an order and it has wrong billing address.? ?The shipping address is correct.? ?Here is the correct billing address Doug Hendricks 3247 N. Dee Ann Ave Fresno, CA 93727 Please

You have any idea how long it SHOULD take Idaho to Tennessee via usps? -- 73 Karl KI4ZUQ

I just measured all four BS170 drain to ground points. Each one is 7.6 meg ohms. Too high? -- Jim / K7TXA Eagle, ID SKCC 10447T BUG 301

Q2 and Q3 have no reading on the drain, Q6 and Q1 read 12 volts

Dave, thank you for your post.? I did not realize when I read the description that the QMX+ had ALL bands, 160-6 in one box.? Now I am interested!!? Hans has made a much bigger step forward than I

The "not seeing it" issue on the website may have been your web-browser's cache. Probably it has resolved by now. OTOH, the direct link Hans offered above should not have that issue:

Hans, congratulations on the announcement of the QMX plus! I just received my midband version of the QMX. Both have their pros and cons. The main advantages of the QMX are that it is physically

Like the QMX, the QMX+ already has an output of about 5 watts. The 10 watt linear amplifier would not be a huge increase in power, barely worth the trouble. And you would have to drastically decrease

BTW, at the first look it seems like there's enough space for a built-in ATU or VHF transverter :-P 73! Jindra OK4RM

When I think about it, it should be much easier to "preprocess" input audio into I and Q paths by CPU/DSP and then use a relatively simple hardware mixer + envelope modulator of the PA. Or, even

It's there. You have to search for QMX+.

Hello, Mark, as soon as the audio input to QMX is interrupted (= no longer detected by the CPU), it falls back into RX mode (fw version 1.0.0.18). Probably a bug. In your case I would guess that the

The talks will eventually show up on the YouTube page for QRPARCI. Last year it took them a couple of months to post them.Perhaps it will be quicker this year. <muhsin.dogrular@...>

Hi Doug H and all. I’m not all that surprised that Hans released an all band version. It is yet another reasonable and logical step along the path to an all band all mode transceiver that many lust

I was able to order one today without a problem. John B. Hayes

Last year when Hans released the QMX, he brought about 500 of them to Hamvention. I believe they all included the enclosure. About 400 of them were sold at FDIM and Hamvention; he handed off the rest
