Ed -
Because the crystal socket is in 'series' with the Emitter of the BAND oscillator transistor. The
'bus' that ties all the sockets together is the Emitter, the Base is bypassed to ground, and the
Collector is the output.
Unless he's short on drive voltage, he may not need any amplification, or a
balun, at all.

I'm curious Garey about why not the other lead? It just shouldn't be
grounded? Maybe a 0.01 in series with the shield side? Or, couldn't he do a
6:1 balun and a 2 cond. shielded cable? (Admittedly, it's more work than
simply one side of the socket and chassis ground.) His impedances would
match better with the balun. I think I'd do that-and I also think I'd do a
little cabinet with a switched set of ranges using your 500kHz suggestion
AND switched BPFs. That'd be 'clean' and pretty nice.
