[hpsdr] New Hermes code available

[Bernd Gasser]

Hi Phil et al,
I'm running a Hermes board from Apache lab and noticed some strange behavior
on 6m TX with FW 2.7 & PowerSDR_mRX_PS_v3.2.10.0 (both from openhpsdr
downloads). - Wonder if somebody else is seeing the same or whether my board
may have some HW-issue?

While other bands are fine, my Hermes somehow locks up and hangs (D14 goes
off) after a few seconds when tuning even with very low drive (10-20mW)  on
TX on 6m (JP3 connected directly to 50 Ohm dummyL).  - To recover, the board
has to be powercycled and restarted.  
I'm not seeing this behavior with FW 2.7b (downloaded from Apache-Lab site).
It just runs fine giving abt constant 120mW output on 6m without any hangs.


Since the different FW seems to resolve my problem I wonder whether  there
any significant differences between Hermes boards from TAPR and Apache Labs
which requires me to run FW 2.7B for my Apache Lab-Hermes?

>From previous postings I learned that Apache-lab FW (2.7'b') may have
different Filter characteristics (LPF) especially implemented for ANAN  -
which more or less means  I cannot use my Apache-Lab Hermes  along with Alex
and Munin by running FW 2.7b (which seemed to resolve my TX problems on 6m)?

Thanks,
Bernd/OE1ACM

Hi Erik,

You are correct in that you can customise the LPF settings in PowerSDR but
in automatic mode the selection frequencies for Alex and ANAN are different.

Ok Phil thanks for the clarification.
I discovered a 2.6b on the apache website so I will use that one for now, I
assume thats the right one.
I  always thought that the logic was switched from the application program
such as powersdr because you can select the different configurations (alex /
anan) there.
