Re: K5BCQ uBITX Relay Switched LPF/BPF board
Tayda Electronics has these standoffs. Adhesive stickem on base. No drilling, no machine screws needed. Several different lengths available.

Re: stone soup ingredient list, what bands and modes are usable
This is great, it means the two bands I'm interested in, 30m and 20m, are good to go.? If I followed the various threads correctly, on 80 through 40 meters, CW was the big offender for harmonics, but

I sometimes get tired of all the Know-it-alls, many of whom may know less than i have managed to forget.. I used to hold a 2nd phone, which was later changed to a general phone. I try to offer some

Re: Stone Soup
It's crude, but you could treat the upper bands like a series of rock bound transmitters with a narrow tuning range(around the qrp calling frenquency, for example) and build the traps accordingly.

Re: K5BCQ uBITX Relay Switched LPF/BPF board
Glenn, Both the 6x filter board and the 4x filter board have 4 holes in them (need to be a bit smaller). I would just drill holes in the uBITX board and use nylon spacers and machine screws.? 73 Kees

Re: VK4PP uBitx LPF BANK add-on Board
J1 AB are selected on zero power on relay control . Would it not make more sense for silk screening to have 15/17/20 as the no power relay ie? for daylight Sota where you want zero extra power draw

Re: Stone Soup
Bob B., that is a very sad story. I suffered kind of the same, when I was a novice in 1970 I was chastised for accidentally using the word "break" on the air. I must have really offended some very

Re: Does anyone have an AGC/Click kit to sell?
I don't have a kit to sell. I have a kit, but no board. I was thinking making it on some perf board. I found a circuit, same idea, but it is two part and controls both the first IF stage and the RF

Re: K5BCQ uBITX Relay Switched LPF/BPF board
Great work on the LPF, Kees. I was wondering how you are mounting it to the uBITX pcb? A screw in one corner i think. In opposite corner referring to the uBITX under, there's a section of ground plane

Re: Stone Soup
Allison Agreed on that wide a trap. I was playing more with the 40 meter VFO bleed through of 4.7 to 5.0 MHz. This for an older QST special built several years ago. Arv _._

Re: Does anyone have an AGC/Click kit to sell?
So, I received Sunil's AGC kit (back in production now) today.? Anyone know how to hook the thing up to a V3 ubitx while I heat the dummy load until we resolve the issues.? Actually it's one good

Re: VK4PP uBitx LPF BANK add-on Board
Ok. Ive ordered 10 boards for testing. I will also try to get it working in combintation with a QRP-Labs relay board and BPF in the 30Mhz LPF spot for spur reduction. Effectively turning it into a 5

Re: Stone Soup
Arv, Anyone that thinks they can make a trap that works over a 2mhz range is also selling bridges.? The trap fpr 10M alone would ahve to snuff 15-17mhz. When you get to that point a band pass filter

I'll make the Gerbers available after they have been tested. These board suppliers who offer the "10 of the 100mm x 100mm boards for $2? plus scoring and shipping" may also receive a "bubble" of

Allison Thanks. That could help others who can work on things but may not have the really expensive test equipment to do final verification tests on their work. It also could to better inform those

Re: Stone Soup
Bill Probably depends on how much software is required versus how much room is available in the Arduino RAM space. Thoughts here run toward using frequency versus a look-up table to set PWM output
