Q70, the audio pre-amp, has a really big job in the uBITX and sometimes gets overdriven by very strong signals. Plus, since i replaced the 2822 audio amp with an LM380 I've lost 8db in audio gain. ?I

worked N2CQR Bill and WS0JM Jay around 7:30pm 2330Z tonight. very noisy conditions up here tonight too. 73 Tom VE3THR back on the BITX40 and 40M dipole.

I'm trying to thin down the project list so I'm passing along my uBitX kit.? Ordered it in February, haven't unpacked the kit yet, never built.?? $130 delivered to your door.?? Benteman@...

Hey Eardan and others: in short, it worked! I applied the appropriate math as follows. For 100ppm: 875000000 / 10 000 000 * (10,000,100 - 10,000,000)? = 8750 Using the uBitx manager, My Master

I built my second AGC kit board to see if that helped.? Unfortunately, after installing it, now I have zero RF power out on TX.? No RFI either :) .? I've tried CW, SSB with the mic that worked

Wasn't me! U gave up around 7:30 EDT. -- John - WA2FZW

Got a faint answer (made out a possible WA2) at my CQ at around 8:00 p.m. DST. Was it you, John? Everything else is QRN and a lot of static crashes. -- Ion VA3NOI

When I try to use uBITX Manager Ver 0.11 with COM port set to 38400-N-8-1, the Raduino crashes and shows "db>4000000" which I assume mean that it has dropped into its micro debugger.? :-(? This is

Ludwig I have measured the output of mine and the 3.3 V figure is correct when lightly loaded. With a 50ohm load it will be considerably less, Because the output impedance is about 1 k ohm Now it

Calling CQ on 7277. Nothing heard so far! -- John - WA2FZW

Dreams coming to reality. Now a hinge system?

Hello, so does nobody have an idea, what might be wrong with my raduino? Which output levels should be generated by the SI5351 chip? The datasheet tells me, the output levels at the clock pins should

Yes. 12.45, same as power source. Also, when i hit the PTT w/o audio, both finals have 3.8v/12.45/0 for g/d/s.? The gate goes from 0 to 3.8 when I hit the PPT.

I suggest writing to Ian KD8CEC. He will proved the source code for beta releases on request. M

A quick answer: The AGC board is fed by a potentiometer (placed across the receive RF input). The release time may be set by a *V* ariable *R* esistor placed from J1 to the ground return. Details may

Have you checked the finals for 12 VDC on the tabs?

Yep, old joke always pertinent: "Windows has detected that the mouse has moved. Please reboot to verify new position."

I agree with Jack, I have some Arduino's and clones,? the main difference I have seen was price. I have windows 10 now and loaded the CH340 driver and it all works just fine.? kn4ud -- Allen

I have probably purchased a 100 clones over the years and, yes, I did have some troubles initially with a few of them, but these were fixed by installing the CH340 drivers in almost every case. Also,

Windows 10 might have some driver problems, but the best bet is to buy genuine Arduino products.? People have reported many problems with knock-off "Arduino" boards.? I use genuine Arduino boards
