Ok Let me clarify. I was asking if the Nextion display has polarity protection?? Or have people been making this modification and catching this error??? I was talking about the power meter not s meter

It is the original power connection point. The v3 to v5 boards had separate power connections for the PA Finals (the IRF510) than the rest of the board. The original thought was to allow for a separat

What is the purpose of the P1 Connection on the v6 board?

RV1 is power output control, see PCB - not the blue twins, those are bias. Raj

GM... For me, (most QRP-CW operating), where following enhancements important: - Nextion 2.8 - CEC Firmware - SOTABEAMS VARI Audio Filter - Kits&Parts AGC - own enhancements for audio - Sidetone other

Agree Bob, Similarly I stick a male N into a female BNC ! Raj

Raj, I know the BNC connector. For me, the problem is that the adapter rotates when trying to connect the PL-259. The glue is to lock the SO-239 in place so the PL-259 can be screwed on and avoid hold

Thanks Mark, looking into your suggestion.

Bob, BNC is Bayonet N Connector, it locks in place. Never had to glue one !!. Best way to go IF your antenna cable is RG8/213 is to make a RG58 jumper about 2 meters long with one end BNC male and the

Hi Mark, I think you are right. What is the RV1? (sorry the newbie question) Rafael

We built a 4.7 db attenuation circuit to connect to a MRF amp. Not what we want, definitely. ; )

Hi Larry, It's not necessarily the closeness of the antenna lead that's the problem. Your symptoms point to common mode current coming back on the coax shield to actually be on the chassis of the radi

What method are you using to reduce the signal output? _._

Hi, I would guess that at too low of audio input, you don't have enough drive for the modulator. Instead, once you have a good level for a clean signal, you might want to try adjusting RV1 so the amp

HI everybody, When transmitting an OFDM signal with 8W until 10W with the ubitx v6, the output signal is crystal clear, but when I start to reduce the signal level (from a line-out of a computer), at

Changes would be things like calibration or mike replacement.

Thanks all, your are right on target, I had been leaking RF into the room! I run the ubitx into an old MFJ-16010 antenna tuner I've had since my SWL days into a random long wire around my back yard. B

Bad antenna match! RF floating in the shack! Use a proper dummy load and test and see these things repeat!

Bitx community, I very successfully installed the 3.2 inch Nextron Display along with the KD8CEC firmware. Ian is a genius. I discovered a discrepancy when I went to build the Smeter and swr bridge. I
