Hi all, a while ago I asked about tuning up valve radios. I've since had 
it suggested to me both on here and by a couple of hams with a bit of 
ingenuity, to use a tone osilator across the meter on the rig.
would I have to make this a permenent fixture or, can I attach a couple 
of aligator clips and simply remove the thing once I've tuned up 
sufficiently.
thanks in advance.
