The Radio Information Board

I put the HHCC on my EVA. It works well. The speaker on the HHCC is like a walkie. Adding the external speaker adds more audio.

I recently bought a HHCH to use on one of my Orions. For grins I tried it on my MRK EVC. Works great! Keep it in mind when you you have a limited space install.

Seeing you've mastered the OOB for the MRK and the Orion uses the same software. It sounds like your plan would on Orions too!

Fowler

The sleeves interchange, but you need the right PN for your model
You also have to change the internal dip switch configuration for the LPE

Looking for IMBE flash for LPE portable

Thanks

Hex editing DOS software
I havent tried hexing Programmer

If you would parrallel the 3.3K resistor (R480) with another 3.3K resistor you get a 136-160Mhz orion You will need to tune the VCOs (I had to pad the tx VCO) You will then need to hex edit the software to get the freqs above 153Mhz If you read it with Programmer software it will show the bandsplit ...

On VHF Orions the resistor is R480
For 136-153Mhz (switchable radios) the value is 1.6K
For 150-174Mhz (switchable radios) the value is 3.3K
No resistor makes it think its a 900Mhz radio
You will need to adjust the VCOs
I had to pad the TX VCO
Works great!
