Fred. Rather than seek a room or roommate, I suggest you hover around the
occupied rooms. Soon as one guest steps out for a break, grab his room and
take over. First ask quietly if it is in use. If he does not answer in 2
milliseconds, claim it for yourself. If he is smaller than you are, he
cannot get it back. Be sure he is not bigger than you, does not stand
taller than you, does not have longer arms, or nor has amplified strength.
Otherwise you may have a room fight to claim the empty space. If he is
stronger, do not waste your time. Rather QSY down the hall and find a
weaker opponent or clear room. 73, Bill, K3ANS>>

The limiting factor with the HP-141T would be the IF selectivity (the
IF uses LC filtering) rather than the phase noise. But I certainly
wouldn't trust the IF of the HP-141T to do an adequate job of
separating the clicks from the carrier in a critical measurement.
It's IF skirt bandwidths are about an order of magnitude worse than
the transient supression of a clean CW signal, so any clicks would
have to be pretty extreme to be detectable.
Al and I used to work together at a company with dozens of HP-141T's
scattered about.
