All I had were a couple of 80 meter crystals - try to "work all states" on
one frequency - it is a chore that I have yet to finish and now they shifted
the 80 meter band! Then I found a VF-1 and was able to do a lot more.
But, as pointed out, the filters were not that narrow and with today's
precision some would call it operating "split!"
Happy Aaint Paddy's day to all!

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.

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.
