Hi David,

Re: MH-31 Microphone low output

Hi David,
It's something I'll bother him about later as we recently were chasing a problem on a PiHPSDR v2 connected to HermesLite2 which turned out to be a tick box for local microphone selection not showing up on that screen.
When I took a screen snapshot it was there - so it was just a problem with contrast.
Two Raspberry Pi official LCD's, one OK and the other with the problem.
73 ... Sid.

Hi, Sid
I can't believe it, even Quisk has this option. Did you try to reach g0orx ? This is the serious issue.

Hi Steve,
That's a more fitting description of what I am seeing.
I have no idea what Bootloader version was loaded when it returned from David a very long time ago.

Hi David,
Not in pihpsdr.
Just the Local Microphone  and Compression.
I have not tried adjusting Compression to see if that would give a usefull boost.

David,

The radio is currently bricked.  I made the mistake of trying to program it with the radio plugged in and turned on.  

I'm also pretty sure that the Pickit 3 isn't any good in the first place.  Tell me - should it show up as a COM port when I plug it in?? It isn't showing up in the Device Manager at all, nor working under Linux either.

Steve

Re-flashing bricked ODY-2

Neoklis Kyriazis
 

Hi all

After several months of waiting (since January 2020!) I at last received the
PICkit and USB blaster that are needed to re-flash my ODY-2, which I bricked
last year. I ordered from Ali Express but was interrupted by the virus!

Anyhow, to avoid making more mistakes and possibly ruining the ODY-2,
I wonder if there are any detailed instructions I can use to repair the SDR.
And also suggestions of what firmware to use for the repair.

My thanks in advance!

Thanks Reto,
As I am using the pihpsdr, I'll do the mod with the electret mic.

No any problems.
Dynamic microphones like MH-31 required 20db preamp option on, unlike electret microphones.

MH-31 Microphone low output

Sid Boyce
 

Has anyone experienced low microphone level from the MH-31?

With the ODY-2's 1W I get no movement with the SWR meter set to 5W PEP full scale.

My setup ODYSSEY-2 --> 100W PA ex-IC737. At first I thought the problem was with the PA.

If I scream into the MH-31, I can talk it up beyond full output, speaking normally or blowing equivalently I get only a few watts output.

Using local audio electret mic to a USB audio dongle  with the PiHPSDR v2 I can drive the amp close to 200W PEP into a dummy load speaking at a normal voice .

73 ... Sid.
