Correct , John. Just the item about parameters is slightly off: they are all saved in non-volatile storage, so they do survive power down and sleep. Willi Von meinem Mobiltelefon gesendet

You cannot power off completely when on USB power - that's by Heltec's design. You can go into sleep mode to minimize power consumption, or you interrupt the USB power. Willi Von meinem Mobiltelefon g

Thanks, Dan, for the pictures. Really weird, haven’t seen thus before, I guess it is an OLED display dying. I still have a few Heltec modules left ( It might be hard to get them on Aliexpress, Ebay or

Can you provide us with a picture of this weird effect? Thanks Willi Von meinem Mobiltelefon gesendet

Obviously you have NOT read the manual, otherwise you would know that you rotate the encoder to change speed, and that a double click of the same knob brings up the parameter menu, which e.g. allows y

Did you remove the yellow foil from the socket?? Willi

Could also be a bad solder joint at the sockets for the Heltec module… You can test this by touching pins 2 and 12 of the Heltec module with your finger (or using a screwdriver…) - see picture. 73 Wil

I am certain the encoder is not faulty - I did not see a faulty encoder so far (they are high quality Bourns encoders, PEC12R-4215F-S0024 or PEC11R-4215F-S00249 . In all cases where people had problem

Yes, it is possible to buy spare parts as long as the supply lasts. But it highly unlikely that the processor has been destroyed… It is much more likely that either something has not been soldered cor

Now after the long press rotate encoder.... Von meinem Mobiltelefon gesendet

Did. you try a LONG press on the black knob? Willi Von meinem Mobiltelefon gesendet

Wayne, You are on the current firmware version, but you obviously are using an old manual. The WiFi function is now part of the main menu structure (since version 2.0, quite a long time ago). LONG pre

Hi Bob, The modified Pinout of the newer halter modules requires a re-design of the PCB (plus some software adaption, plus code to find out on which version it is running, to maintain compatibility wi

I think it is completely passive, just a potentiometer... how would it get power supplied? Willi Von meinem Mobiltelefon gesendet

The inline volume control is an excellent idea for headphones or external speakers! Willi

As far as I can see, you still can start the echo trainer mode by touching a capacitive paddle (but not with your straight key), and of course alternatively with the black knob. I don#t think I am goi

Ian, 1.) yes the transceiver jack is a mono jack, and must be wired to the transceiver as a straight key. 2.) the way TRRS jacks are wired (with ground on the second ring), you probably have to use a

Hard to say what is going wrong here. Maybe others have similar observations? Can you make a short vireo to show what is going on? 73 Willi

The suggested OLED will be a problem, as it is only 128x32 - the Heltec module has 128x64. Willi

Maybe it is just going to sleep - you can change the time-out /and also turn it off) with the parameter „Time Out“ - see p. 38 in the user manual. Willi
