RRC1258 MkII with IC-E2820 - Microphone Question

[dj1aus]

Hi,

I am moving finally into a house but in the meantime I will have no antennas on my old flat so I want to make a step between the final moving and place the Antenna to my remote QTH and use FM Transceiver from there.

I have already my IC-7200 working there via the RRC1258 and I am thinking to use these boxes for a short time for my IC-E2820. This should be used just for few weeks - so not a big investment.
Now my question:
In the manual is written:

Be aware of that the original microphone can not be used without the HM-133 adapter boards. If you do not have them use a simple ICOM microphone like HM-103 or HM-95.

What function is involved in this "does not work"? All functions like basic PTT and Audio or just the additional keys on the HM-133?
I do not want to buy the adapter just for a few weeks operation - can't I use the HM-133 just as a classical mic?

Please help!

Thanks

Hi

the HM-133 has no real PTT-switch. All buttons including the PTT is sent as data messages to the panel. So Adapter pcbs are always needed for the HM-133

Hi,

ok I understand - if I install the adapter pcbs is the RRC1258 only useable for the IC-E2820 until I remove the adapter pcbs again?

What shop can ship the pcbs quickly? Can you suggest one?

Greetings

Yes

You just remove the pcbs when you do not need them

I think it's fastest from our webshop, I doub't that Difona has them in stock
