Hi Allard, 0.1 is intended as 0.1uF.? In Italy we usually write 0.1 without u or uF. 73 Gian, I7SWX

Hi John, Did you measure the input power consumption for your different input voltages? I am considering to deploy a node in a context where input power is scarce and am looking for a power-lean

Never mind. I get it now. 73, K7TFC

OK, lets try for some closure. When my raduino crapped out on me while trying the wrong wire to calibrate it. I picked it up to see if I had the right wire and a blip occurred with the display, and a

I think the convention is that all capacitor values are in ?F (that's microfarad in case the "mu" character doesn't show up on your screen) unless otherwise indicated. I'm going to try this AGC in my

0.1 uf, they are. - f

If thinking about getting a scope, you could do far worse than investing a little time to read up on this blog

The 5.5nF and 3.3nF are standard values, .006 uF or 6nF and .003 or 3 nF are not standard valuesand would therefore be very hard to find, assuming some manufacurer actual makes them in those values.

Thanks for the info! Slowly getting my Bitx40 together. Hopefully in a couple weekends I will have it operational! RichKC8MWG

Thanks, Randy, for finally getting me pointed toward a centralized source of info on the BITX40. I'm new to this group, and enjoying all the various posts about problems and solutions, but didn't know

I built the AGC board a while ago and it worked quite well, except the audio level was a little low. I had previously removed the cap from pins 1 to 8 on the LM386. I ended up putting a 10uF between 1

John, Ultimately, what was the issue with the low output? Bad IRF510? It would be nice to have the solution at the end of this thread. Thanks, Marco - KG5PRT [email protected]> wrote:

I just checked again and still no UPLOAD button. Guess wait and see what support has to say. 73 Ken VA3ABN

I want to use my VFO BITX40 for CW only with a straight key or keyer. ?It covers 7.0000 to 7.1900mHz. I will use the DDS BITX40 for LSB. ?It covers 6.9850 to 7.3550 mHz approx. Where can I find mods

Hi Gian, thanks for the schematic. There are two capacitors labeled "0.1". Just to be sure, does this mean 0.1 uF or 0.1 nF? 73, Allard

Thanks, that helped! I never use Chrome due to privacy issues (I use Firefox), but for that use I suppose it's okay... RichKC8MWG
