This is very curious.? The same USB cable connections / signals are used for the diagnostics as are used for the CAT commands.? And these lines just go directly to the microprocessor, which then

How do I test: "Is the Q set to DIGI mode " Thanks, Sam Hanie samhanie@... 623-219-8130 [email protected]> wrote:

Probably a dumb rookie question but .... If CW is working AND the terminal based TX diagnostic tests into a dummy load are OK then ... Is the Q set to DIGI mode when you are trying to connect into

Yes Device Manager has: 2 Sound Cards 1 Serial port (com17) Diagnostic runs. buttons test good, voltages look OK. What else? Thanks Thanks, Sam

Good, had me puzzled. So where the bottom axis now reads: -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10 11 it should read: -9 -8 -7 -6 -5 -4 -3 -2 1 2 3 4 5 6 7 8 9 10 11 An informative graph,

Chris, It’s clear that the BS170 maximum Vds rating is greatly exceeded on 80 and 160 meters and this is indeed due to higher gain in the FETs at lower frequencies. I saw this gain difference vs

Chris, I guess I need new glasses, as I now see the band designation in the prior posts.? Looking at the SWR of 1, the measured voltage does seem to follow projected power as frequency changes.? A

Hi Sam, can you still access the QMX+ diagnostics via Terminal? Do you still see the serial port as well as the sound card on your computer? Cheers Nick G0OQK

Hi George? Bruce is correct that you can use the 0.33 on all QMX and QMX+ kits now. And QDX kits too.? Depending on when you bought your kit you may have received enough 0.33 to complete everything,

FYI On my plot I should of suppressed "0" and "-1" on the x axis

The plot does not address power. Only peak voltage across the BS170s. However the 160m has higher power than the other bands. You can see that 160m and 80m exceed the 60V ratings of BS170 and are

Got it, thanks Bruce. George

It's all 0.33mm (#28) wire. Cheers - Bruce K1FFX

I am building my second QMX. I am now winding T501 and following the transformer1_00c.pdf document as specified in the assembly_1_04f.pdf. The assembly manual specifies using 0.60 mm wire and the

Greetings, Had a storm come through a few days ago.? Heard a "POP" and my 12v brick was dead. Fuse was blown, replaced the fuse, but the 12v adapter was still dead... Replaced it with a new

Check out CW Academy on the CWOPs website.? Lots of resources including scheduled classesfor improving CW proficiency. CharlesK5KXJ

On 1/3/25 I had a CW practice / rag chew session on 40 meters. I worked only one station: Date / Time Call Bnd Frequency Comments Mode Name Power Rec Snt SPC# 1/3/2025 14:58 KE8TBM 40

Thank you for the update Hans, my mid band kit has the black cores, I just need to finish another project and then I’ll get started with it. I noticed that you also tided up the formatting in a

Techs have CW privilege on 15m.? ? 21.0675 is supposedly a "Slow CW" calling frequency (forgot what group was designating that..). When I couldn't hear you yesterday, I answered a slow 15m CQ and
