KE0GYC, That battery would not be good for QSX (10W transmitter), the battery protection would likely kick in at RF peaks and shut it down.? Also full charge its 12.8V but average voltage during

Yes, those R/C battery packs are very useful and readily available at your local Hobby Store along with the chargers. 73 Kees K5BCQ

I've done a fair amount of international ordering, and I do see it vary widely from country to country. This is my first time with a shipment from Turkey, and I'd put them on the slower end of the

I have explained this on http://qrp-labs.com/shipping and http://qrp-labs.com/faq#stuck The shipments leave Turkey and the last event in the tracking indicates that it left Istanbul. Thereafter, in

John, That dummy load - where did the design come from? I presume the leds give a rough indication of power? I'd be interested in the schematic &/or source. Regards Nick M0HGU -- 'People need

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
