No no no, the highest frequency filter does not go on the main board. The
main board slot is numbered 0. The highest frequency filter should be put on
the relay board, in position 1. Have a look at the relay board, the filter
positions are numbered 1 to 5. Slot 0 is the one on the main board.
How on Earth did I misunderstand that? Duh! Thanks for straightening me out.
Aside from that blunder the build is going well. I still have to build two
of the filters (next rainy or windy day when I can't do antenna work), and
at some later time the OCXO.

Re: How can i see the raw data from the GPS receiver.
Well I never.
Alan, I actually have a few of these in the bits and pieces draw that i bought some time ago for another project..
That saves on ordering and waiting for those now.
Cheers, James.

Re: How can i see the raw data from the GPS receiver.
Ah yes the old MAX232 chip, i once used that in a circuit to read the data from a fire alarm panel using a very basic organiser type gadget that i used to keep notes on etc. I'll look up the MAX232 circuits now.
That's jogged the old grey cells a bit.
Thanks Simon.

Hi James,
if I remember correctly most GPS output RS232 or similar. I converted the serial data from a GPS 'puck' to TTL using a MAX232 chip or similar then read it as a serial port with an Arduino for my home brew WSPR tx.

Simon.

Subject: Re: [QRPLabs] QCX on WSPR ? I found out why the power was slowly rising on the 20m QCX!?
As suspected, it turned out to be capacitors in the low pass filter.? ?One by one the capacitors were replaced and the RF output behaviour checked.?
There was no change when the outer 2 x 180pF (C27+C28) caps were changed, but a noticeable change when one of the inner 390pF (C25) was changed and then perfect when the other 390pF (C26) was changed.??
I changed each cap with a 250V ATC ceramic chip cap.
The output power is now very stable and the supply current has dropped.? Output is 3.5W with 13.8V supply.? Some squeezing of the turns may improve this.
I also experimented with the 30pF capacitor from the drains of the finals to ground.? The efficiency went up slightly without it.? I put a 30pF trimmer in its place and found best efficiency at almost no mesh of the trimmer.

Re: QCX $49 5W CW transceiver introductory video
Oh Hans,
I¡¯ve just watched the video.
If I¡¯d known about the built in test equipment, I¡¯d have had one of these from you at Newark.
I suppose it¡¯s my own fault for not paying attention to all the marketing material but even though I¡¯ll probably never use it as a transceiver, I just love the idea of that test gear being built in.
Unrelated, it was really nice to meet you there for the first time and catch up. ?

Hi all
I was asked to produce a little video for a potential radio club group build of the QRP Labs CW transceiver . So, today I made a quick 20 minute introductory video. This is just a one-take, un-edited, no-frills chat video. See?
This is nothing like Roberto IZ7VHF's amazing video at which shows all aspects of the QCX assembly, operation and on-air performance, and is beautifully produced. So watch Roberto's for the complete deluxe experience!

Re: Power on issue solved on my QCX :-)
Had same issue, low power to ATMega\LCD (poor contrast adjustment, random microprocessor resets).
Cause turned out to be residue on the leads of L6, despite the solder joint looking good it exhibited resistance.
This case fits with Hans findings of no issues with 100uH, at a guess
the residue is a by-product of the manufacturing process and therefore variable.
