Mine is for mostly WSPR and other digital modes so I use the presets to accommodate. Can't speak to the multiband sensitivity yet, but I empirically compared my earlier QRP Labs receiver on 30m to my

Hi Mike, congrats in figuring out all the mutilband connections. I also built a similar rx but I found the vfo option gave me a lot of birdies and clicks as I tuned across the bands. I eventually rebu

The heart of this project is the VFO kit which controls an included Si5351A DDS. It uses the same pcb as the U3S kit with several parts omitted making for easy construction. VFO output is CLK0 on the

I ordered mine last week, and am going to try it out with both the phasing module and with a Teensy per ZL2CTM: http://zl2ctm.blogspot.com/2019/06/homebrew-804020m-ssb-sdr-phasing-rig.html Ryan Flower

I have just finished soldering a QRP Labs receiver. I haven't powered it yet because my Teensy software is not ready. I look forward to try both standard phasing method and 3rd method ssb. Then a comp

I decided to try the QRP Labs receiver on my "good" antenna (inverted L @ 40') and use it with my Raspberry Pi3 WSJT-X station. Because the Pi3 uses a USB Signalink soundcard with mono input, I had to

I recently built and installed a QRP Labs polyphase adaptor to use the QRP Labs Tayloe receiver with software lacking support for I/Q decoding. I had socketed C1 and C2 when I built the receiver to su

I wanted to free up my IC7000 for "real" work so I purchased a few kits / modules from QRP Labs hoping to build a dedicated NDB / Navtex (and/or DGPS) receiver. The result is a GPS disciplined VFO dri

Hi Martin, I have done a similar mod to two U3 receivers I have. I connected the relay drive to the spare switch on the front panel so now I have a USB/LSB select, which I use for listening to voice S

I just successfully built the receiver and polyphase and this is definitely something I will consider adding to that build. I'm trying to make a complete multiband shortwave receiver with everything c

Hello! Yes I have build a receiver with the polyphase module, and seems to receive well. Really good sensitivity - and frequency accuracy after changing the xtall on the Si5351A to a TCXO 0.1ppm cryst

Hi Martin, thanks for sharing a great Idea. I have built 2 receivers with the polyphase networks. I use one 24/7 for spotting wspr on 40M. It works great. I yet have not needed to listen on LSB but wi

Hi all, I was wundering how many build the #Receiver (https://www.qrp-labs.com/receiver.html) with #Polyphase network module. Before I used little 2-way header socket jumpers. Here is a photo of the P
