Hi Arv, It is more likely the work that is being discussed and done here will be incorporated into a new version and not squelched the new version. 73, Bill KU8H

Found the issue with the 'D' files...converted them...ran the X files thru FreeDFM with good results. I think we can color this one done. 73, Lyn WA4GEH -- *"You see, wire telegraph is a kind of a

Hi Warren, There are all kinds of abuses that are possible. But the question was about the digital modes actually being SSB signals. I only addressed that. It turns out that music does not go well

We should have some way to indicate when too much mike gain is applied. A diode, cap and resistor watching either audio or IF or RF peak signal levels, sending that to a Nano analog pin should be

Joe, KN4OND I have been thinking along the same lines for a couple of months. We have lots of information that could be organized to support focused work on each of the problem(s), but no document

Yeah, that’s my LPF.... Actually its the wire for my 40m dipole. [email protected]> wrote: -- Adam Goler, PhD Cell: (425) 985-8700 "Fear is the mind killer."

The 4x LPF/BPF boards have arrived and I need to get one in Warren's hands for testing (in addition to the other 6x LPF/BPF boards). A little more layout tweaking will make the interface leads even

Hi Raj I'm pretty sure its not the power connector...I saw swinging power (past tense) and am now registering no more than about .5W max output, so something has cooked.? In the past, that typically

I have just about permanently taken the top off the case the radio is mounted in, and have a cooling fan connected ... hoping that will be enough going forward.?? how hot are the transistors

I am sorry to be so ignorant but what exactly are you talking about with the IRF510 Tabs? Can you show a picture of how to properly ground (or not ground) the device and the PC Board in general? All

Bill Your analysis is true so long as the tones, or the voice if that is your mode, do not overmodulate either the audio or the RF chain. In the case of the uBitx running 10 watts of SSB, whether it

Hi Fabian, have you been able to perform the above mentioned test QSO? I‘m still not sure which sound you meant with ?....?all others that i heared was only "piep pieeep" like a space computer

Fabian, no problem at all, your English is very good and you described your doubts very well. With 'book' I was a bit kidding on the length of the post. In any case you rised a good point. Grounding

Hi Joe, The digital modes use SSB and put the tones in through the mic amp. The bandwidth of the SSB filter determines the maximum width that will pass through - not the minimum. When you connect your

About those loading coils in the background....

Hi Allison, Unless I win the lotto (and probably not even then) there won't be a day when I spend a kilobuck on a radio. There might be a day when I buy a Spectrum analyzer (or make one). But there
