Nigel, Got it thanks Even though I don't completely understand the readout from the Arduino serial monitor I was successfully able to program and load both frequencies? I needed, Is their any way of

Pr Rr. HW-7 oldie and good.? Problem is the mechanical encoding of the dial to the? microprocessor.? Not easy and mechanically, maybe harder.? ?Reason is the 5351 needs a complex set of commands

Sounds like you've got it under control! My outer box was a little too snug, so I did wind up filing down the actual printed circuit board a bit. There was that tendency for the sides of the boxes to

I have a QCX20 in the mail and I'm wondering if it might be worth replacing the LPF with one of the 'new' (1999) CWAZ filters presented by Ed W3NQN in QEX,

Hi Al, I haven't soldered the boxes on yet, following the check, check and check advice.? All parts soldered are the correct parts and in the correct place. I checked each resistor and cap for the

You may need to tune around a bit. When I built the kit I found the oscillator runs low 26.998 MHz is mentioned in the instructions; it's going to vary from crystal to crystal.? I remember in the

I have been asked about where I got my parts, and of course I thought I would share this information and what I actually ordered. I ordered the parts from Bama Tech located in Germany.? They are the

Hi all, Building the OCXO for my U3s, all boxes built and good. Got to the part where the oscillator needs checking, C3 fitted, but no oscillation. On pin 2, 27mhz out, I have near enough full input

PR Your request for a Si5351a add-on for the HW-7 is interesting. It would be possible to use the Si5351a VFO <https://www.qrp-labs.com/vfo.html> unit from QRP-Labs. That includes an LCD for

In 1963 I went on DXpedition to Sark as GC3PAI/A. A member of the party was Andrew McDonald who later became G8BAR. He brought along his transistorised version of the G2DAF receiver, which worked very

I'm not having any problem after a week or so as of this writing..I did try other types of glue but they took to long to dry so I could let go of the wire.? The super glue hardened in a few seconds

Hi. I too made up sleeve and button to operate the SW1 / CW button: I wasn't prepared to lose that functionality when I put the little rig into its smart new case! I think it should be included in the

My QCX80 seems to work just fine..just finished the build a few days ago.? But I find that the audio gain is way too loud and I need to adjust the AF control almost to minimum.? Just a touch above

I have just dreamt about ?revisiting the good old G2DAF reciever, using the ?ProgRock as three bands front xtal converter, and the ?SI5351 vfo, for the tunable IF!

Hi all. I have a Heathkit HW-7, and would like to upgrade the RX, with a barebones SI5351 module, without display, without modifying the front panel and case, using the existing analogue slow motion

Hi Kurt Yes. Already covered on http://qrp-labs.com/qsx 73 Hans G0UPL http://qrp-labs.com

Hans; Will this rig have the ability to utilize some of the more modern digital modes by connecting to a computer like FT8? 73; Kurt - W2MW

Ok, you heard it folks. Leave the man alone so we can have new toys sooner rather than later! :)

Hi all I have put together an information page about QSX, which you can find here http://qrp-labs.com/qsx . Please feel free to share this page. To allow me as much time as possible to finish the
