Lee -
A T-4 was an early 4 Series transmitter that had no PTO or BAND
Oscillator. It was only able to transmit in TRANSCEIVE under RCVR
control with an R-4(any), or under crystal control. There is a photo
of one on the front cover of the T-4X manual, and the schematic is in
the back of the manual. It's essentially a schematic of the T-4X with a
couple of large white spaces! :-) It was sold for a while with a
stacking cabinet to make a 'transceiver' with more receiver features
than a TR-4.
They were originally sold with the 'feature' that they could be
'upgraded' at the factory by adding a PTO and BAND Oscillator with a new
front panel. I think it sold for $270 as opposed to $380 for the T-4X.
It just occurred to me, I wonder if it had anything to do with the
NOVICE prohibition against transmitter VFOs. I don't recall if that
prohibition was still around in 1961...??
The photo was on the front panel of the T-4XB manual, and I have seen
ONE T-4B, but I doubt if more than 300-400 of both models were sold, if
that. We just saw one here that had a serial number of 254, and it was
an 'end of life' convert according to Bill Frost.

Hello, the conversion of the T-4s at Drake and also by Drake for
customers
raises the question of "Just how many T-4 reciters of both the w and w/o
speakers are there out there?"
I enjoy the T-4 with the R-4 - nice and simple. Bill's 0018 has to be
one
of the earliest "alive." that has been converted.

I am glad to learn about the T-4 reciter's serial numbers. Mine is
0018 and
I had it converted to a T-4X when I sent the unit in for a repair.

This is from Bill Frost about the "special edition" T-4X.

Hello Kihwal,
If memory serves, I believe your T-4X was originally built as a T-4
reciter.
The T-4 was not a big seller, so somewhere around the end of the
life of
the
T-4X, the T-4's that were in stock, where unpacked and converted into
T-4X's by
adding the VFO sub-assembly. The serial number stayed the same, as
it
was
already stamped on the chassis, carton, etc.
