Terrell and others -
OK, thanks. I got my Novice in 1957, but didn't know how long the
prohibition lasted. I got my General about four months after my Novice,
so didn't have to worry about it! :-)
I knew the 2-NT was definitely addressed to the crystal controlled
Novice licensee, and has a '75 Watt' input mark on the PLATE meter. I
don't think the T-4 had that mark, and that made me doubt a little!
MANY of us built our first transmitter out of old TV parts in those
days. I was flush, I had TWO crystals in the 80M Novice band. My
'receiver' was a BC-454 'ARC-5', and the IF was just about as wide as
the Novice band. The entire band was about 1/8" wide on the dial, so
didn't have to tune much......

In 1960, I was a NOVICE (WN6BTS) and there was, indeed, a prohibition
against using VFO's. All novice license holders had to use only crystal
controlled Xmitters. I made mine out of old TV parts and a 6146, grinding
down some old crystals with sandpaper that older hams had given me.

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.
