The more I play with the Nextion ?Suite and get use to it the more I like it. As with the button you just click on button and it is done for you, it has a field for you to put in what you want it to do and you are through. This is the easiest for me to do I don't have the coding ?ability that alot of you guys have so I have to go simple. I don't ?need a large LCD because I want to keep my total rig size down for my uses. I have a 7 inch display on a pi that I got from buydisplay, it works but it was no plug and play and by time I was through I was wishing I had of spent $10 more and got the one that was plug and play. I do feel that their are a lot of these displays out their that can do the job and from what I see their are people here on this site that can do it. The more interest we have in doing this the more envolvement we will have in making this work. I am only using a 3.2 screen for what I need if I need bigger then for me I will consider ?buying a IC7300 ?that has the internals to back up the large view. This is just me and I am by no means trying ?to offend ?anyone.

That is good news, I would look at one of the trifilar interstage transformer being shorted.
I mentioned the numbers earlier.
If the transformers are fine then a dry solder in the RX chain or filter would be the culprit.
A DC voltage check on RX BiDi amps would confirm they are OK or not.
A general check to know if a 3904 is blown (very unlikely) is voltage across Base and emitter.
It should be around 0.6-0.7v.
If you get no voltage then check if that stage is getting Rx 12v. Also unlikely in this case.
I will bet on the trifilars as for now!

I think OTOH that this problem is not due to your accidental interchange.
CW is generated by the first mixer stage so it is something in the 2nd stage or
later. Check BFO frequency and IF stage (2nd) for any bad solder and specially
check the T3-T7. Shake them gently and see if any change.

Hakan,
Got it! the only severe damage could have been cause by PIN 3 +5v and 4 Gnd.. now this would have
connected to volume ground and center variable pin. If the volume as at minimum as it would be
when you switch on then the volume control would be damaged.
5V would have gone through the volume ctrl to PTT line which would have sustained the voltage.
This would have happened if the center pin of volume control went op.

When I inserted the Raduino one pin to the left the raduino was toast!
The damage depends how many pins did you shift left or right.. one of
the pins has 12v and that would fry the Si chip or the nano.

Re: BITX QSO Afternoon/Evening, Sunday, June 3, 3PM & 7PM Local Time, 7277 kHz in North America, 7177 kHz elsewhere.
Why not keeping just one frequency like, 7177 which is common to both sides of the Atlantic and the other oceans?

John,
I use an Arduino Nano AD9850 external vfo? with my Corsair II, that uses a free turning optical encoder and the Corsair digital display.
Currently working on another version with a 20 x 4 lcd display, 2 memories, changeable step sizes and RIT.
Also has up/down band buttons?so the lcd shows the same frequency as the Corsair, when on normal sideband.
My objective was have a free spinning tuning knob and to avoid mechanical pto wear problems in the rig and external vfo.
Using the Raduino with cat is certainly in the realms of possibility but you would?probably need to add a buffer amp and?certainly a low pass filter.

Re: micro bitx: strong signals from broadcasting stations
What does local mean? A nearby station on medium wave, a station just above the 40 meters band or an FM broadcast?

Would you switch off power and plug in the 8 pin like you did by mistake and take a photo
for us? That would help troubleshoot.
I am quite sure the connector can be plugged in only one way!

That's probably (;-) why I got a brain collapse and shifted the 8-pin contacts for the raduino resp. uBITX. I realised it after a short while. Everything looks ok, but I hear no signals, just birdies. Not a sound of even strong broadcast stations. Any hints?

Congratulations.
And I can do all that without learning to write and compile GUI programs under Windows or Linux? Or this RPI OS you mention?
Also, I prefer wxWidgets so you should use that instead.

Re: digital modes - how to connect computer line out
I used a USB soundcard, more because my laptop has a combined audio port for speaker/microphone. But just two 3.5-3.5mm cables from the soundcard to the speaker and the microphone connector of the uBitX. Simple as that
