Same experience here as others have reported. Distracting clicks, severity varies by band, less intense with AGC off. Fiddling with AGC settings can mitigate somewhat. Present with dummy load or

Started my build, but I got to L502 & T401 and I'm stuck. The manual calls for both to be FT37-43. However, one of mine is a dull black, while the other is shiny black. Are they the same? Now I'm not

Hans, One bug, and one idea. Bug:? When doing RF image sweep immediately after startup via console (doing nothing else), the graph shows no rejection on 80m.? When I switch bands and come back to

Alrighty, I got the replacement PCM1804's in, and the replacement went off without a hitch.? I cleaned up the pads, put down a touch of paste, hit each pin with the knife edge soldering iron, gave it

Sounds good, I just cleaned the backside, I didn't really need to immerse the whole thing, but a good scrubbing with an ultra-soft toothbrush leftover from the dentist and 99% IPA did the trick.? The

Hi Martin, I used 91% isopropyl alcohol and a very soft toothbrush. ?I was gentle but did the whole bottom, which I have rarely done in the past. So much cleaner. ?The shack has good magnification

Hi, What is the washability of the main PCB?? Naturally, I wouldn't wash the display/encoder boards, but I might like to remove some of the flux I've added in the QMX of Theseus (as I'm now going to

That's what I get for posting way too late at night! My overall point, though, remains: namely, that due to the different impedances, the performance of the output audio amplifiers will not be exactly

Hi Larry I did reply to your helpdesk ticket almost immediately the same day you wrote it. But it would appear that some email providers such as comcast.net are further ratching up their spam filter

He must have had the junior lab assistants helping because I think mine jumped 50 places last week.? If it helps, Larry, I am in the 120s and I ordered around the first of October last year.

For an output power of 40 Watt, the input power was: 80 m - 0.4 Watt; 40 m - 1.2 Watt; 30 m - 1.5 Watt; 20 m - 2.2 Watt. The amplifier supply voltage is 24 V, the current consumption is about 3 A. The

Hi Larry, Please check this site regularly to estimate when your order will be fulfilled: https://www.qrp-labs.com/qcxmini/assembled.html You're in #465 73, Wei, AG6AQ

Hi Larry, Here is a list of the factory built kits. https://www.qrp-labs.com/qcxmini/assembled.html You are 463rd in line as of March 14th. I don’t know how many he is making a week right now but

Hans:? I'm unable to get any info from your site re: my Dec 2023 order for HI-Bands QMX (factory built). Order No. 81173. When I go on site and request support, I'm told I need to give my 'ticket #);

what manual.? none was received and i have not been able to find one online dave

I've mentioned this before: before shipping, all boards have their bootloader programmed and verified, and that there are no shorts on the 3.3V rail, and that there is successful USB connectivity. The

Does the manual not describe what it use is??

Thx Adrian, Hans and Allison. Appreciate the feedback. Will proceed carefully. Greg Yahoo Mail: Search, Organize, Conquer On Thu, Mar 14, 2024 at 9:49 AM, Adrian YO3GFH via

15M? results say the amp has issues. Either low bias or LPF filter?? 20M 10W for 2 in seems? a bit low as well (I'D expect 13-15W) At the same time the 40M results suggests maybe other things going

Yes, 100% agreed with Allison. MOSFETs don't have an intrinsic frequency limit like a bipolar. Which is also why good board layout and attention to parasitics is important because you can easily get
