There was no change or adjustment to the firmware between the radio working at 100% of expectations, to the present output deficiency. I swapped out Q90 to a steel can 2N2222 a while back and all was

What year is this build, please? looks nice.

What is your experience with drivers for this external card on Windows XP and/or 10? Immediate integration of USB connectivity to the board seems like a good way to neaten up a final product and minim

Yes, direct langage toward setting parameters for WSPR mode in TX would be fantasmic. I'm home on surgical recovery and will be restricted to brain exercise only ( as opposed to tower reconstruction)

I bought these, and reasonably-shipped: https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F352066947527 Ted k3rta

Clark, Please forgive my lack of clarity. I'll try to fashion up something better and make a go of individual relay measurements within a week or so; I'm about to have vertebrae C3-C7 fused and bracke

OK, here we are: On 80m and 60m, only the filter between the T/R relay and KT3 shows strong RF. Power out on 80m is 2 watts CW, 1/2w SSB. 60m shows 1 watt/1/2 watt. On 40m and 30m, only the filter at

Not a bad deal (as of date of this message) considering those "kits" on eBay that self-destruct upon contact with electricity: https://www.newegg.com/p/0TF-0002-00002

Please don't think of me as obtuse, though, in what way is your rectangular opening "upside down" for the display? I would second the recommendation of using a surrounding bezel to take care of this,

Excellent line of investigation to follow. Having replaced the finals (from Mouser) with predictably no change, I swapped out the Nano. New, known supplier, etc. No change. The relay power at K1 - K3

Raj, I'll take a look at D1 & D2. Mark, I don't recall the source though I've picked up two different batches off the Bay over time. I know eBay sources are to be distrusted, though the ones I've used

Outstanding value! Thanks.

It seems that I'm experiencing an issue with a V3 board where I get less than a watt of CW carrier, and nothing on SSB output except upon initially pressing the microphone. I did something that appare

Will this include all parts - the relays, inductors, etc, or mainly the board and relays? Tnx, Ted k3rta

QRP Labs has some nice and very innovative stuff though I'm not shopping for new hardware, necessarily. This was arguably a question better suited for an APRS or WSPR forum, maybe even an EMCOMM group

Has anyone set up WSPR for position report and message use? I find Bob Bruninga's web pages read more like hypothetical possibilities than actual application but that's probably me. If I'm going to be
