TenTec used hot melt glue in the VCO modules of the Paragon transceiver,
so this glue probably has good RF characteristics (hopefully). The
expansion and contraction of this glue over varying temperatures did cause
the solder joints to fracture over the years............this was the
downfall of the Paragon.

In 1991 I bought a second hand TenTec Paragon trx ....still going strong as
my main HF transceiver. But tnx for the above .........if VCO ever
fails I know what the reason could be.
