Dear Jerry
this depends on the type of preamp. It is impossible with selective preamps
due to the built in filters. Broadband preamps with built in 2H stop can also
not be switched between fields. Newer instruments will also complain as the
frequency is recognized by the spectrometer.

Dear AMMRL,
Has anybody tried replacing a HPPR preamplifier with one for a different
frequency? For example, replace a 500MHz preamplifier with a 400MHz or
600MHz one. I appreciate your inputs.
Cheers,
Jerry
