BAD Signal reception on RAK-Wireless devices?

Support
1

i just found out, that my Rak wireless sx1262 devices receive most signals (on shorter distance) only with

example: rssi -69 snr 7,3
and rssi -47 snr 7,5

whilst in direct comparison my old tbeam, same position, same antenna, sx1276
show rssi -55 snr 11,0 (up to 14 sometimes !)
and rssi -96 snr 11,0

BIG DIFFERENCE IN SNR !

i reproduced these results with 3 different rak devices !

all on firmware 2.2.21 or above.

i am using a rak wirelss as a main router, on top of mast, maybe it would be better to use an older sx 1276 device !
or maybe this is an artifact in measurement? or a firmware problem ?

can someone do the same testing and check if there is another problem with RAK devcies here?

Not the same radio, are you having range issues?

yes, not receiving stations, that can see me …
reception only up to 8km, sending up to 25km and more
there is a lot of noise on 869,5mhz here , as seen with sdr

probably it is an artifakt in measurement of very strong (short distance) signals in high noise…

maybe someone else can test reception a t-beam against a rak sx1262?
