Some rigs will take it fine, as is. Is it the one with amplifier in base? that type will surely work with all modern rigs and proper adjustment of the amplifier.
On some rigs, with low Z mike inputs, a high Z to low Z transformer can match the high impedance crystal element of the D-104 to the mic input low Z. See Hammond transformer catalog for these. 72, Stuart K5KVH _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
