Interface KRC2 with MK2R

Hi,

Is there a way to connect KRC2 to the MK2R outputs in order to switch BPF /
Antennas with Icom radios?

Regards,

Robert

Re: Interface KRC2 with MK2R

The KRC2 supports the band decode outputs of Elecraft, Icom, Yaesu,
and Kenwood -- so the answer should be Yes.

But you mention both MK2R and Icom - you cannot use both at one time.

Re: Interface KRC2 with MK2R

In reply to this post by s57aw

The answer is yes. Since the KRC-2 does not decode Icom CI-V data,
configure MK2R to output HEX/BCD "Band Data" on the ACC ports (one
for each transceiver) and connect that BCD data to the "Yaesu" inputs
of the KRC-2 (again, one for each rig).

You have two choices for the source of HEX/BCD data ... option 1 is
to have MK2R/Router generate the HEX/BCD code based on the frequency
returned by the transceiver (CAT decode) while option 2 is to allow
the logging program (N1MM Logger or Win-Test) to set the appropriate
output using the microHAM Control Protocol.

This capability is not limited to the KRC-2 ... any decoder capable
of HEX to 1 of 16 or BCD to 1 of 10 decoding (e.g., TopTen BD-Y or
W9XT BCD-10, etc.) will work the same way.

I must have missed the CI-V decoding. If that's the case, MK2R+ can
(re)generate CI-V data on the ACC port (again one for each radio)
which can be fed to the KRC-2. The KRC-2 and MK2R can not be connected
in parallel to the transceiver.

Re: Interface KRC2 with MK2R

> The KRC2 does analog Icom band decoding, not CI-V.

MK2R+ can not regenerate Icom analog. In that case, MK2R+ should be
used in the HEX/BCD mode or the KRC-2 connected directly to the Icom
transceivers. If the KRC-2 is connected directly to the rig, it
could be used for BPF selection based on the band and another decoder
can be driven from MK2R+ for antenna selection (multiple/alternate
antennas per band) using the microHAM Control Protocol data from N1MM
Logger.
