The #253 automatic antenna coupler was discontinued in 1995 due to lack of
sales (which is why it is not an easy item to come by as used equipment, and
we rarely see them come back to us as trade-ins). We had them in production
for about 6 years and at slightly over $1000 retail it was not an item in the
budget of the average ham. We will continue to service the 253 in the future,
as we do with all equipment we have manufactured.
Raining in Sevierville again today - that's 16 out of the last 18 days
according to the local newscast.
