Hi Reji

The MK1 exciter board was
somewhat experimental and had a few issues so I never
developed it any further or offered any boards or kits.

I addressed all issues with
the MK1 with my MK2 project so you could take a look at the
documentation for that and see if you can modify and upgrade
your MK1.

One of the
problems I experienced with the MK1 is poor bandwidth in the
transmit strip especially on the higher bands so that is
prob why you have problems with 21Mhz and 28Mhz but it could
be an issue with the bandpass filter.

Good luck with your project.

Regards

Andy de G6LBQ.
