For a receive only situation many would say the mag loop would be your best bet. With your application being receive-only much of the concerns raised really effect transmitting and matching.

Vince, You are not receiving WSPR signals. What do you see if you remove the audio lead from the RX? Do not take it out at the computer end, that can confuse if Windows thinks there is nothing there.

Hi Hans :), Well said Hans. I used to say that my customers dragged me kicking and screaming towards success!! Keep up the good work!! I am trying to get FT8 up and running. Whoops!! Now there is a

Thanks Alan for the reply. This is what I have: U3S Settings: 0]? 0? 014,083,600 RX??????????????????? 12? 0 ------------------------- 1]? 0? 014,083,600

Hello Eric, Take a look at this solution from Palomar. No other parts needed except coax and the wire. We used about 50' of RG-58 and it worked well with 100 watts. Palomar has a number of solutions

Good day Erik; ? Years ago I put up a Mini G5RV when I was living in an apartment. The 300 ohm twin lead came off the flat top at about a 45 degree angle. My first G5RV which had a 102’ flat top

Till now I have used the received module with an amplified wide band magnetic loop. Now I'm looking into a dipole. Due to space constraints and stealth requirements the 1/2 size g5rv multi band dipole

Hi Ken, I like the case nifty idea certainly makes me want to look at other ideas for the enclosure. I see you have set your U3S for 6/4/2m bands just wondering which transistor the IRF510 or the

Vince, You are seeing the signals, lines 1 minute 52 seconds long starting exactly on the even minute? 20m is open? You do have the U3 calibrated correctly? Or, do you mean you are decoding spots but

Hi Justin I wish I could have something useful to share but unfortunately I do not... I do not consider myself well organized or managing time well. Too much going on, too many balls juggling at the

Hi Hans,? would you be willing to share how you managed to learn the time management skills necessary to accomplish all that you do?? from where I'm sitting it seems to be a great deal of stuff!?

Hi Justin You cannot. Only SiLabs can prepare a chip with this "non-volatile" start-up configuration programmed. And you probably have to order 100,000 of the chips or something crazy, to get them to

Hi Randy I have no update or change at the moment. 73 Hans G0UPL http://qrp-labs.com

Hans, Any chance of an update on the estimated November availability of the QSX? 73, Randy, KS4L

Directions are on this page: https://www.qrp-labs.com/ultimatelpf.html Step 5 of this doc: https://www.qrp-labs.com/images/ultimatelpf/assembly_ulpf.pdf (has directions & picture) 5) Relay/diode on

I suggest you have a look at Application Note 6, which describes the VFO/SigGen Set ... it's based on the QRPLabs VFO kit and LPF relay kit. Best - Bruce K1FFX

Well, I think I am really close.? WSPR is showing receive signals in the waterfall but I am not getting any spots.? I have synced my PC clock with NIST.GOV but wonder if the problem could still be

Hi how does one go about writing to the one time programmable memory for the start up configuration?? -Justin N2TOH

Hi, Can someone point me in the right direction in adding the relay kit with BPF to an already existing QRP receiver driven by QRP VFO kit?

Kurt, Referring to the manual and the link to the actual design I see these components are part of the 700Hz filter, I would expect some reduction after a 2.2n capacitor but I am not familiar with the
