<blockquote TYPE=CITE>Fred,
<br>Which model 4 pin exciter do you have?
<br>Kevin >>
<p>The exciter is a TLD5322B and the channel element is a KXN1018C....
by the way
<br>i can only get 2kc deviation out of the exciter, does anybody know
which
<br>capacitor i have to change in the element?
<p>Thanks

Well, I have no experience with that exciter. I use the TLD 8732A
<p>As far as the deviation goes, you should not have to change anything
in the element because of deviation. If you are able to net the crystal
on frequency, you should be able to get MORE deviation from the exciter
now that it is on 220. Why? The crystal oscillator has been multiplied
more times (18 instead of 12.) 417 cycles of deviation at the oscillator
is necessary to make 5 kc. deviation at the output on high band (2 meters)
the same oscillator deviation (417 cycles) should net 7.5 kc. deviation
on 222 mc. You should have more than enough deviation on 222.
<p>Sounds to me like there is a problem with the buffer amp (Q404) or first
tripler (Q405.)
<p>Do you have the schematic, and trouble shooting procedure? It should
still apply.
<br>Does each stage tune at a precise peak? How about the tuning slugs,
are they all the way into the sleeve or way out?
<p>Did you put any caps on the channel element to net it on frequency?
If you did you may have taken away the ability to deviate the oscillator.
<p>If you cannot get this transmitter to work, I can send you a TLD 5382A
style exciter and channel element.
