Hello every one, I am new to the reflector, as I am begening my =
collection of heathkit rigs.. I had a SB-102 as a young ham ( 11 ) and ' =
upgraded a while back.. now I want to get back into it ( heaths ) , and =
i picked up a nice SB-300. Well , I unpacked it.. hooked it up.. and it =
hears really well.. stable as a rock.. the only thing recieve wise that =
i dont like.. is that it warbles a bit when TUNING a cw station.. but =
when i stop twisting the VFO, it is ROCK STABLE.

Anyways.. the meter seems to not work on incoming signals.. if I turn =
down the RF gain.. the meter DOES reflect to full scale.. and then back =
down when I re apply the RF gain to the rcvr.. any ideas? A working =
meter is a MUST hihi.. also, its missing the AM Crystal filter.. im =
going to assume this is why it does not recieve in the AM mode.=20

I am looking for a copy of the manual online.. altho.. the prices seem =
pretty outlandish.. Im actually thinking of replacing every part in this =
to try and restore it to new condx.. ' origional ' dosent concern me.. i =
want it to function perfectly.

Oh, and issue #2, the " frequency alignment line " ( i dont know what to =
call it, does not spinn when the small dial is turned.. I looked inside =
and the small wheel.. and the ' line adjust plastic 1/2 sphere " dont =
mate up.. is there souposed to be a tiny wire in there? Ideas?

Ide also like ideas on cleaning the inside.. its not rusted at all.. =
just dirty.. i tryed some windex on the coil cover.. and almost took off =
all the lettering ( ugg ).

Thank alot guys! Hopefully Ill be in touch with some of you really soon!
