Henning and Glen, Thanks you for the feedback. All interesting questions. I sincerely hope someone with the test equipment can duplicate and fill in the blanks. The only test I can think of

I got my uBITx wired up today and powered it up this afternoon. Not much on the air but I did go out to my jeep and fired up my Yaesu FT-817ND on 10 meter and had my wife listen down in the shack.

I stay at the red roof inn across the intersection by the gas station. I had stayed at the holiday inn but they wouldn't let my bengal stay there. Maybe more of us are going and we could have a

Attached is an idea that might work nicely for a drive control that can be varied in software by the NANO on a band by band basis. The original drive control, RV1, is removed and a few parts added,

This could be an OK idea if the input drive level is right. I’ll try it in the RF lab tonight… Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ Owner -

“I was not able to get more than 10 W output power at P1dB” You are working with TWO devices in push-pull that are capable of almost 20+ watts per part with properly designed support

Hello fellow hams: I seem to have damaged my tuning encoder so that it can't work right(button push doesn't work). Please can anyone recommend a suitable replacement from either Mouser, Digikey or

HI John and the group. I did the mod with the 100uH and 1nF cap on the MIC input fo the preamp board, It did cut the interferance/feedback out completely. However, it has also cut the MIC gain

MIght try this as a 3 element:

Skip, Thanks for the reply. I did as you said. I had to reload about four times! Seems like a register value was not getting reset when I did the reload or something. It finally took tho! tim

I made the error of clicking the encoder instead of pushing PTT when trying to zerobeat WWV while having that high pitched tone come in, I found that the BFO got a saved shift point up +2kHz. I ended

I get my replacements from Digi-Key -- their part# PEC11R-4020F-S0012-ND is a direct replacement for the original encoder and works really well. It's a genuine Bourns encoder too and not that

Henning, I put the case together on the ubitx for now. I'll have to wait till I open it up again to check on the filter bandwidth and the bfo frequency. I tried pulling the windings on T7 away from

Jacob, This sounds like what I probably did! I'm not sure what you mean by "zero the sideband off WWV". Do you mean set it so it sounds the best? tim ab0wr "Jacob Farnes via Groups.Io"

Nice! I like your boat anchor gear. Is that an old S-38 I see? tim ab0wr "Nelson" <ngtdlt@...> wrote:

Dana, Does the encoder actually work? Can you change frequency? You might be better off add a small normally open pushbutton switch near the encoder and paralleling it onto the two encoder switch

Yes, tune the carrier to 0Hz (tone goes quiet/away). In mine a high-pitched tone appeared and confused me, so take your time and try to ignore the birdy signal. The problem with doing it to an AM

Hello Nik, I am confused. A 100uH and 1nF filter has a cutoff frequency of 503KHz, so am not sure how it can affect your audio. You also mentioned CW, and CW works directly on the unbalance of the

HI John. Sorry, I was a bit unclear. CW power is normal, no effect there, I get the full 20+w output. But the SSB is low now... I will check it over tonight, try it with and without again, and post up

we can get mpsh10 in smd MMBTH10 AND the pin out is same as present device. They are cheap enough on ebay. Hope the info helps. regards sarma vu3zmv Regards MVS Sarma
