[Elecraft] K2 Tx lock enquiry

Thu Jan 3 12:59:11 2002

Actually we do make a special version of the K2's IOC (that's where we store the
band tables) that restricts TX to the ham bands. Several hams in Singapore and
Thailand have requested them from us in the past. It is available for $29.00.
While not listed on our price list at the moment (due to low demand) you can ask
for the 'K2 TX Limited IOC' when ordering.

The frequency limitations Nicholas mentions are a little more restrictive than
those we have in the above part ( ex. stopping at 7.100 instead of 7.300). It
sounds like he may be interpreting the rules more restrictively than necessary,
but if there is a demand for a special 'M3' version of IOC chip, we can do it.
