BTW, every single spot of N4QA shown in the screen shot below of the current 'RBN week' is from my stock QCX-17 : Also seen here: http://reversebeacon.net/dxsd1/dxsd1.php?f=0&c=n4qa&t=dx 72 /

In an attempt to prove that she's an eight-band QCX rig, the stock QCX-17 is running a CW beacon, somewhere within the lower 5 kHz of the USA 12 meter band. Power output is 200 milliwatts and the

RE T1 and pcb de solder / re solder As we all know T1 is prime RX ... If u can't hear-em can't QSO-EM Solved my problem N3AAZ

Sorry, I meant to say QSX, so it should be suitable for either of the QRPLABS offerings.

That should be within the realm of QCX power though, right? A 10W SSB rig should draw under 3A average by a pretty good margin.

Hey, John, N3AAZ, Many thanks for the hint about the "variable (tunable)" audio filter. I've been wanting to improve on my 7-band QCX rig's performance while receiving, for example, CHU on USB on its

Vernon, I have run the PA Amp on 630 M for over a year on WSPR and it is about 5 watts- except for last 30 days as I'm testing an MF Solutions transverter. I did mount the amp in the U3S case with a

Hey there, Nigel. Not having a stock QCX-30, I can't speak to its performance on other bands. But, as for my stock QCX-17, I have enjoyed more QSOs with it on 30m than on any other band...would love

Niger, Of course T1 is prime but not as critical as one thinks :>) This pcb with 30m T1 is a four band xcvr Parallel C1 and Outboard LPF and Bypass onboard audio filter and Add variable (tunable)

There are 3 parts of the QCX that are band specific: input tuned circuit, output low pas filter and class E amplifier. I also have a 30m QCX. We should have QCX activity that isn't a contest so that

Hello again from ZS land :-) Following on from my posting yesterday in reply to Bill re: "A somewhat more complete description of my (ab)use of the QCX-17 and QCX-80 transceivers, today I became aware

Thanks for the tip Richard. I'm out of town for a couple of days, but I've got an LCR meter on order so I'll check those caps out when I get home, as well as my inductors. My first time winding

Hi Al Yes. Non-critical. The most non-critical place for the low one would be C21 or C22. 73 Hans G0UPL http://qrp-labs.com

Turnigy makes a good product and I've used a lot of their packs... However read the information its 2.2AH 1.5C that means the max current is about 3.3A and standard .5C charge rate. For QCX that's

I found this on Amazon today: https://www.amazon.com/dp/B00USRD91W/ref=cm_sw_em_r_mt_awdb_4muTCbG8JHMRP It's a 3s li-po 2.2Ah pack w/ protection built in for under $25! Seems like a great option for
