Clean up that D104 and get it ready(preamp or not)  then go to this page

the enhancer and the audio is outstanding.

The "Silver Lollipop" D104 mic is an icon of the past. Depending upon how
old it really is (it was only recently discontinued although it was
manufactured for over 50 years) you might not be giving it the best chance
just hooking it to a K2. The original D104 was a crystal microphone with a
very high impedance. The K2, like most newer rigs, is designed for a dynamic
element. Later D104's used impedance transformers and I believe some even
had preamps to match the newer rigs. But if you have a true "old" D104, the
impedance mismatch can cause a very tilted frequency response. If so, it's
easy to cure, but it's worth looking into if you intend to use the venerable
"lollipop" microphone on phone.

Hi

I  inherited this silver lollipop recently with the numbers "D-104 /
T-UG9" on it. It was new-in-box and it seemed a shame to let it languish
in the cellar. So yesterday I wired it up to an 8-pin mic connector and
had my xyl judge the audio out of the K-2 in test mode (SSBA BAL) while
I fooled with the OP1 bfo setting.
...
but now that I see that ssb qrp is viable, I guess I'll give
it a try again some time.
