OK, the TSW team now has our 2.8" color TFT screen operating fully with both a keyboard and a mouse for control. ?With the BITeensio card and this display you no longer have to touch the screen at

I do have a buffer board but its in the FT-840. I added a 220 ohm resistor in series and I am no longer effecting the radio receive with the SDR connected, not hearing a difference plugged/unplugged.

I think Joe uses a buffer board which should be the best way to tap it. And alternative is using another 3904 (emitter-follower) . The gain in the RTL I have can be reduced by 42db via the software.

Thank you Allison. That sounds like a good experiment, I’ll give it a go. Joe

MPJA has them and not very expensive....? see....? ?http://www.mpja.com/Handwheel-Digital-Encoder-100PPR-5VDC/productinfo/33106+MI/ That is a 100p/turn unit and works well for me in other

Kees, That Rigol with tracking generator is the a really good tool.? Build up a return loss bridge for SWR measurements out to the machines max 1.5ghz.? There are several good and easy designs on

Joe, Keep in mind a RTL-SDR is not an insensitive receiver.? Its good enough on its own. so putting the gain and mixers of the ubitx ahead of that means the noise floor is increased by the effective

Thanks Iz, I like the waterfall for a visual representation, it helps me hunt for signals and get a sense of band conditions. So what you described is taking the IQ and turning it into audio to get a

A little delay in shipping the 6x LPF board (if you have paid and want your money back, just send me a private email). The problem is that the Port to Port (S12/S21) Isolation of the LPF board is too

Thanks for the info Jack. ?I'm going to spend a few bucks and try them out. Tom

Hi Fabien, I watched your video, and it seemed to me that the only problem was that the SSB stations were not tuned in yet.? I would do this test: 1.? Set the BFO to 11.997.000 2.? Make sure your

I don't see what might be the purpose of using an RTL dongle. It's 8bits ADC limits its dynamic range to a mere 48db or so. Otherwise tapping is a good idea. All the points you have identified might

OK, Just making sure the corrected version went out.

Whaaaooo! Super much thanks again at all HAM here which helping me with new comments, so very thankfull for all!! I have made an little video yesterday late evening at 18.45utc (in germany 20.45uhr)

My bad, I was not paying enough attention when I ordered the speakers. And what I did order, and receive, are 40mm not 2"/52mm. No matter, they will still work reasonably well. Wayne WA2YNE

Fabian, The factory c code sets the USB calibration to?11997000 if out of range (as would be the case if not yet calibrated), so this would be a good first choice. For another reference point on

Speakers arrived the other day. Supposed 2" speakers are more like 1.5", 40MM. 4Cm. Have not tried one out for sound yet. Wayne WA2YNE

Cheap way to have slow and faster tuning with an encoder is to have a two-size knob.? Smaller part tunes faster and larger part does fine tuning.? Those with a metal turning lathe can make a

I think I found a good tapping point. C215 before the filter and shield to ground. C216 seemed like there was a lot of noise, I don’t think it was more signal, just more noise. C214 looked ok but
