HA-10 Warrior & HX-10

[Larry Knapp]

Dave - I don't know about the HA-10 "hash" noise...perhaps others can comment.
One reason for using the 3B28's is they are not as susceptible to flashover as
the 866's are.

As to the HX-10, Marauder.  These units were only manufactured for perhaps two
years or so..1961-1963 (don't have the exact years off hand).  Heath definitely
sold more TX-1's than HX-10's.  The Marauders began to complete with the more
compact size transmitters then available and of course the newer transceivers.
It was the last of the "big-O" transmitters for Heath.  They are not uncommon;
not rare either.  I have one and I have seen them listed on eBay and I've seen
several at midwestern hamfests.  They are perhaps the most stable and best
sounding SSB/CW transmitters that Heath made (to that time); AM is not that
great...usable but not like actual plate modulation.  I consistently get very
excellent audio and keying reports.  I can literally pound on the table and the
transmitter will not move.  It's definitely decent.
