Subject: Additional 285 Transmitter

BOD & Repeater Committee Chairman:

John AK3Z and I delivered the "Second Line" transmitter for 147.285.  This
unit is a 250W Motorola that uses a hybrid exciter/driver (solid state &
tube) and a dual 8330A Tube PA.  The channel element is set for 147.285 MHz.
The unit was used as the primary xmtr for the TPARC repeater until it was
replaced by the Quintron.  The Motorola was then used as the "hot standby"
xmtr.  As with any of the gear that I manage to procure from the old TPARC
stock, I leave it up to the club to do with as they please.  It can either
be used for 147.285 OR retuned for 145.410 to replace the current Motorola
exciter/Henry PA.  It's entirely up to the BOD and the Repeater Committee as
to its disposition.

Dan is looking for a spare exciter and additional receivers for us.

The transmitter is sitting in the back room of the club station next to the
Quintron.  It can be moved to the barn for storage if necessary.  The GE
Prog-Line cabinet will be moved to the barn. We would have moved it by now
but for the inclement weather.  It has been cleaned out and is no longer
needed.

Also delivered to the club station is a cardboard box with driver, exciter
and PA tubes in it.  These need to be secured in some way.  The 8330A PA
tubes and the transmitter PA assembly should not be handled by persons that
are not familiar with this type of tube due to the beryllium oxide ceramic
material used in the construction.  A manual for the transmitter is also in
the box.

Obviously, the Motorola transmitter will have to be thoroughly tested and
checked for spectral purity prior to being put on the air.

As far as the "new" 147.285 MHz repeater is concerned, it looks as though we
may have to add a repeater controller to replace the one that we received
from TPARC which we don not have schematics for.  The cost of this component
is about $150 to $200 new This will provide receiver/transmitter interface,
CW ID for K3PZN, and a few other functions.  The Qunitron transmitter only
requires the application of a control ground to key up. I am not well versed
on repeater controllers, so either Bill N3WM, Larry WX3F or someone else can
probably help us with this and make suggestions as to which
manufacturer/model to chose.

Doug and John will fill you in at the next board meeting. I don't see any
necessity in my attendance unless the BOD deems otherwise in which case I
plan to be ill with some highly contagious fatal disease next Wednesday.

Questions?  Concerns?  Comments?
