[Hammarlund] hq 145a tone chirp/blip when tapping on the table. normal?

[Fernan Bolando]

Hi all

me again. ive noticed something new :)

when i listen to a steady cw tone/signal and a relatively strong tap on the table
will cause the the tone to chirp or blip. it does not drift though, just a
sudden blip blip thing. i just wanted to know if its normally for the old
tech.

stability seem good after warm up. i can zero beat on a cw tone, just fine.
