Hi Marinos,
Methinks that the Ostrich at 28.266 ( 28.276 in my K2/100 - and a BIG one)
could be one of the mixing products of the LO (PLL) and the BFO. Am thinking
about major surgery in an attempt to get rid of some or all of the many
internal spurii in K2, which can be a problem in single conversion low
frequency IF receivers (and transmitters), but no time at the moment.
You are not alone.
73,
Geoff GM4ESD
