<DIV>Hi Guy</DIV>
<DIV> </DIV>
<DIV>Simple solution, just slacken the LMO tuning capacitor shaft to the worm
gear, rotate it 180 degrees and retighten.</DIV>

<DIV>Hi Guy</DIV>
<DIV> </DIV>
<DIV>I would check the frequency of the LMO output with a frequency counter
before doing anything else. It should tune from 5.5 - 5MHz plus a small
overlap i.e. it tunes from high to low when the SB101 tunes from low to
high.</DIV>

of the Heathkit listserve,<BR><BR>I think I have a problem, and it's not
in Houston....I got the 80 band tuned up on my SB-101, so I thought I'd
try it on the air..I found an 80 meter LSB group of hams talking ,and
having tuned up the 101' into a dummy load, I turned it onto the antenna
and called...they came right back and said I had a nice signal...no
tuner...I asked "what frequency are you showing?" and he came back
"3900khz". Only one problem...I was tuned to 3691khz!! I
checked this again on 40 meters...same thing...when I transmit a signal
using my Elecraft K2 on 7400khz, the 101' is reading (and receiving) it on
7181khz...Did I do something wrong with the LMO? I checked it's
range of movement,and with the tuning unit dialed all the way
counterclockwise, the variable cap is almost closed; then, five
turns to the right and the cap is fully opened, as I recall. I
didn't check it on any other bands, but at the moment, it would seem the
LMO's output is 219khz too low....right? It's reading 219khz low
exactly on both bands..... Help....<BR><BR>A bit of history. I know
virtually nothing about the history of this 101'....I bought this one,
with another 101' and two HP23 series power supplies from a nearby ham for
$100. He had bought them from another ham, hoping to get one working
one out of the pair. He never had time to delve into either of
them....<BR><BR>Guy<BR>WA6OQQ,<BR>On of the hams at Heath<BR><IMG SRC="cid:X.MA1.1457945167@aol.com" title=http://www.qsl.net/g3oou border=0 alt=http://www.qsl.net/g3oou datasize="117949" DATASIZE="117949" ID="MA1.1457945167" ><BR><BR>

<DIV id=yui_3_16_0_1_1454362217059_5225>Glen,<BR clear=none>Thanks for
your help....I followed some of your advice, and the advice that I
didn't follow came back to bite me.....I acquired a couple of SB-101's
for a song (well, a song plus $100, but it included two power
supplies....)....and I've been "bringing the 1st one 'back'" so to
say....cleaning, checking, going thru the tune up routine, etc......I
rebuilt the LMO on an SB-101....removed the front panel, etc to get to
it...had to do a lot of general cleaning as the entire dial assy was all
gummed up. I took apart and cleaned the LMO...lubed it,
removed and cleaned the stops, but<I> I didn't do the braid
thing</I>......I used a high end light oil for the lube...from
Kroil....I got it on the air last night, loaded it into a 75 ft long
wire w/ no tuner and joined a group at about 3800kc or so but they kept
reporting I was "jumping all over the place"...as I listened, I heard
them, but the frequency kept changing...or "warbling" as you say. My
signal was plenty powerful, and the group was spread out all over the
California coast up past San Francisco...so the 6146B's were really
kicking, so to say. So, I reread your email and this time,
downloaded the file on LMO rebuilding. I'm going to attempt
removal of the LMO w/o removing the front panel--can I do that?
Maybe I'll have to remove the "escutcheon" to set the dial on
right...Anyway, now I think I've got to do the braid....I was going to
use a bit of "soldering" or maybe I should say "de-soldering" braid...Is
that ok? Anyway, I should have followed <I>all</I> of your
advice, not just some of it. One other interesting thing....when I
tuned in the stations, my RF gain control didn't work, and when I looked
at it, the diode on the middle terminal had let go...but wow, did the
receiver<I> have a lot of gain</I>. When I hooked it back up, the
gain seemed to back down a bit. I thought I'd play with that just
a bit to see if the control is somehow hurting the overall receiver
gain...<BR clear=none></DIV></DIV></DIV></A><A href="http://www.qsl.net/g3oou"></DIV></DIV></DIV></DIV></BLOCKQUOTE></A><A title=http://www.qsl.net/g3oou href="http://www.qsl.net/g3oou" moz-do-not-send="true"><BR>
