I don't know, Don. If he installs the KPA100 the lack of temperature
stability will be a serious issue, at least for digital modes. My experience
was that before installing the temperature compensation mod, the drift was
unacceptable even on CW. This was not a problem before the additional heat
generated by the KPA100.
If Randy would like to keep the K2 the Temperature Compensated PLL Reference
Upgrade Kit (item #E850138 for $24.95) is still listed on the order form for
K2 Revision A to B Upgrade page.
The information for that mod also suggests installation of the BFO mod kit
(item BFOMDKT for $10.95) and a firmware update if the K2 has a firmware
version less than v2.0.
Those are relatively inexpensive upgrades and worth doing to improve the K2
if Randy doesn't want to go the full A/B upgrade path right away. I don't
know which would be a better investment between the K2 and the 7300 as I
know nothing about the 7300. One other thought to consider is the difference
between having a radio you can fix yourself vs. one where you have to send
it away to get fixed should something break.
