Hermes Lite-2 problem with receive

[Theo Van Der Schaft]

Last week assembled HL2 with NAdr2 filter  board ,and try to setup for receive 

However from initial start cannot receive anything ,only noise?

If i configured also for transmit. I can test transmit and seems to work. I can see a waterfall signal and signal on the mic dignal meter . I tried  with different antenna's megactiv 205 sft and a sigma hf360. on both i cannot receive anything? For test i also hooked it up an other sdr  RX888MK2 to the same antenna's and the work  normal? What could be the problem.?

Ik follow the setup  settings  from  ON7OFF (zerotohero) but nothing helps.

Is it possible to do a check if receive connector is working?

 Now have feeling my HL2 is totaly  deaf. 

since i received the kit on 03-06-2026, and it has never received , it maybe a doa?

Any suggestions, what to do?

Thanks Theo

Hi Theo,

Some possible explanations for this problem are:

1. LNA gain is not set to an adequate level. Check the videos regarding setting the LNA. Try some other software.

2. Connector between N2ADR board and HL2 is not installed or installed incorrectly. Please send a photograph of how you have these connected.

3. A relay on the N2ADR or HL2 may be stuck. Please try a direct RX antenna connection as described on this page.
