Hello @richonguzman

I have a request and wonder if it is possible for you to implement this in future updates!?

Recently I have set up a digipeater on a remote summit (OE5REO-13) to improve LoRa APRS coverage in my area. I have set the digipeater to work in cross-frequency mode ... at home I have a two iGates, one is listening on 433.775 and the other on 433.900 exclusively for this digipeater.

The settings of the digipeater are:

RX
433.775
SF 12
CR 4/5
125 kHz

TX
433.900
SF 11
CR 4/7
125kHz

This works fine with one exception ... for messages the cross-frequency mode does not work as it should. If somebody sends a message via the digipeater (no other iGate, ... is in range) the answer/ACK will not be received.

Image

So I suggest to add another field where one can choose whether to digipeat messages on RX or TX frequency. Not sure if this is easy or hard for you to implement ... so please let me know! It could probably look like this on the WEB UI:

Hi,

you want to control wether GPS packets are being crossfreq repeated and message are only repeated, right?

this "could" be added .... but also you could have just a single dedicated digi that does not change frees for this (although you have 2 already there)

i get the special use case for this... will check how complicated the idea is to be implemented.

Perhaps ... if it is possible change the whole BEACONING setup in the WebUI from

to

Probably setting different time periods for beacons on APRS-IS and RF is also a good idea (like on the screenshot)? This are only some ideas I have, no need for you to implement these changes if it is too complicated or you think it is not necessary!
