Hi
BFQ43(S) listed as Si - N Transistor VHFOutput stagess 36V 1.25A
Power Output =4W(175 MHZ) equivalent 2N6255 with the same
ratings.
Does this info help?

Exactly what are you referring to?
I have a couple of the Silke RCA-700's here.

Heh... Yes, it is interesting to have lived long enough to have seen
changes, but it is also good to go along with those changes instead of
staying firmly mired in the past. As I recall, the cycle-hertz change was
made sometime in the 60s.

Good For you Joe! I too, went through the cycles-per-second to
Hertz transition.
To all else,
cycles-per-second = Hertz
Kilo cycles-per-second = KC = KiloHertz = KHz
Mega cycles-per-second = MC = MegaHertz = MHz
From this point add what ever prefix that applies.
Gee, What kind of table do you
What? What? You mean they changed it!
I still say 5 KC deviation ;-)

Hi, all,
One of the few Dayton acquisitions this years was a Motorola APCOR unit.
Apparently it was designed for medical/EMT use and is supposed to be able to
do full duplex. Does anyone have any technical info on this unit they would
care to share? It looks like it might make a decent
Al
The APCOR unit came in a number of flavors. Could be MT-500 or MX-3XX or
some other HT as the transmitter and receiver. IIRC there is a 10 Watt PA.
The duplexer is usable. The unit should be 10 frequencies and 10 PL tones.
Probably the PL tones are selectable separate from the frequency.
Al,
I picked up a 12 watt APCOR unit a year ago, but have not found the time or
patience to repair it, let alone try to modify it. The Coronary Observation
Radios act as vehicular repeaters, and operate on the UHF Med channels in
reverse- that is receive low, transmit high. They are based upon

I still need this info

Thanks RSG,
Your info will be of help, guess I will not go for the Rangr. Using 2 radios
will increase power usage, and I need to keep this low, for portable use.
As for freq. change, this of course would need the duplexer to be retuned
for the freq. required, not that I believe it would be

Hi Chuck, My 2 meter machine uses a 600KC Split too.
OH, have you had that 5KC deviaion checked by your doctor lately? ;-)

Id like some information on this Power Amp:
Standard UHF RF Power Amplifier
Model RPA-5/90WA
25A input at 12VDC
The heat sink is finned aluminum, measures ~19.5 x ~10.5 inches, and is
notched for rack mounting.
Is this amp rated for continuous duty at full output, or is it
Neil, very useful graph. I think it is actually easier to use than

hi all
i am working on a motorola MSR 2000 Vhf low split 30 watts.
i am looking for used channell element here in the group before thinking of
order them,
maybe someone have them on the table
i need the

rx=144.850
or
tx=147.270
rx=147.870
thanks in advance if you can help me
Coy,
I've never seen an MX500, but I remember using the MX300R for an Air
Force project back in the mid-80's. This was a ruggedized model that
was encased in a black rubber jacket. Although somewhat reliable, they
were pretty expensive- about $3,800 per copy with DVP encryption.

I was looking at using a MFJ-9406 6 Meter SSB radio for a 6 meter
remote base at my reapeater site. Any Ideas on how to get a COS/COR
signal out. I thought about using a CAT Tech SQ-1000 Squelch board but
didn't know how it would handle the pulsing nature of SSB. Has anyone
tried this or something
