Update: I had a 3.2 display here so I just loaded that one and it worked right off. I'll just get a 3.2 front piece and forget the 2.8. It's already on the way back to Amazon. Looks like I got

I'm afraid I'm at a loss joel, I want to ask you to short the RFIN and Out with a jumper, Remove the Volume wire and put the switch in the off position just to make sure that its the agc

Correct voltages are present, 5V is 5.23V Joel

Morris, I had the same problem with my 2.8 Nextion. Try "UBITX_Nextion_GUI_V3\ubitx_28.TFT". Make sure it is a TFT file and not an HMI file. There are others that will work but try this one first.

So at this point we have a replacement unit pulled to the side for you out of the latest production batch if that is what it comes to again thank you for taking the time to poke at it to try to find

Trying to load nextion firmware on a 2.8 lcd. The load is saying that the model in the firmware and the model of the lcd don't match. Is that a known problem? I have double checked that I have the

Tim, On a strong signal with the antenna connected the S meter pad just tickles my auto ranging meter, basically nothing there. Without a antenna there is nothing, 0. Joel N6ALT

Everything seems to be in order, How interesting. Can you get the voltage off the S-Meter pad for me? with a signal present and with the antenna disconnected? Last thing to check before i'm going to

Hi Tim, I shorted the common pad to the off pad and then I tried all the pads individually shorted to the common pad, very slight difference between them. Joel

Did you short the Common to Ground on the switch pads? Just leaving it open is actually setting it to a SUPER SLOW agc motion and will give you even weirder results. Can you show me where the yellow V

Tim, It doesn't make any difference where the switch selection is, the audio sounds the same. Attached is the best picture I can take. Joel

Just jumping RF In/Out wont remove the agc from the circuit, It has a shunt element that would still be active :) IN order to remove the shunt element as well you would need to put the switch pads

Yes I did, with a exacto knife. i made sure there was no continuity between the the two traces after the cut. Strange thing is, I can short between the RF in and the RF out and there is absolutely no

From the quality of the picture all looks right, Lets check a few things! Did you cut the RX trace that is now underneath the AGC board? wrote:

Tim, Thanks for the reply, here is a picture of the install. Joel N6ALT

HI Joel, Can you send us some pictures of your installation? Low volume can be caused by a few things, Most notably a bad RX path or A bad RX gain pot setting. Tim Keller wrote:

Great idea paddy! <PEPINDIA@...> wrote:

Hi Tim, I'm sure Joel, the OP won't mind me hijacking his thread, he is my brother in law:-)? I installed the AGC board today and noticed that the volume is very low now, in fact I have to crank it

A simple mod would be to bypass the input and output the? ?crystal filter with two miniature relays. It may not sound great but should be decent enough for SWLing Paddyvu2pep/ac2dt
