things are working a little better, I gave a few "adjustment taps" and hit everything with iron as suggested by some here. I do find the /uBITX_6_N8ME_2_VU3GAO_Mods.zip (

No clue, Ray. I haven't done much work on this. Others have some experience in the group. Perhaps they can answer?

Bad maths, please excuse moi. 96000 samples are processed 2048 samples at a time. That makes it 96000/2048 = 42.875 hz per bin. [email protected]> wrote:

Mark, Unfortunately, no. The current implementation (see rx_process in sbitx.c) has 2048 bins spread over 25 khz. So, each bin is about 42 Hz. There are no signals that are narrower than this so make

Pardon my ignorance on SDR processing. It seems that when you select the narrower bandwidths the FFT bin frequency size stays the same. ?IOW, say there are 200 bins at 25 kHz bandwidth, each bin

Art, ok, good to know that root-cause was found and you are waiting for replacement. Hope that you will have V2 back in full order soon and you will enjoy it. - P

Petr Yes did that also. The switch is faulty. Ashhar is going to have sales send a new pcb. Thanks for your suggestion. 73 Art N2AJO

Hmm… that might be cool. ?Can you try both?

Art, one more thing > did you tried to swap the flat ribbon cable (grey one) connecting the encoders pcb and RSPi? You could isolate where the issue is... -P

Art, I know that maybe you all tried already but in case > it all looks like disconnected or not detected Vol encoder in V2. As you confirmed on last vid that swapped encoders PCB from DE unit work it

Ashhar I removed the pcb with the two switches from my dev unit and plugged it into my V2. The vol level can now be adjusted.

I don't expect it does.? I think the manufacturer is rather generous(?) with his power output claims.

Good idea, I was thinking of a pseudo oscilloscope showint modulatio in place of the spectrum display?

Hi Ashhar, It’s really minor but it would be nice if there was an easy to see indication of transmit while in digital mode. ?The only indication is audio and FR sliders switch to SWR and Watts but

Ashhar Grist video trying to adjust vol leveli using the function button. Second video shows me using my keyboard to manually adjust the vol level. So believe the software is functioning correctly Art

at 12-16V and 6-10A the PA cannot give 100W !!

I have this schematic which is for a 70W amp.? I think it MAY be the same as for the 100W amp.? The only difference may be some component changes.

Unfortunately, I can't.? The amp is an XTD-PA100 (made in China), which I purchased from ebay.? I've included the blub on it although I don't know that It will be of any help.? Perhaps there are

Can you send a schematic of the amp?
