Screen modulated transmitter it puts out 100 watts CW on the original non warc bands 80 through 10, 6 is a lot less. However it looks really ugly on a spectrum analyzer. Tuning mine up on 3870 into a dummy load it makes nice power with spurs down only 25 DB at 1935 and at 5805.
Doing the Math it appears these are the fundamental and the 3rd harmonic of the fundamental in the VFO unit. The thing doubles to make output on 75 meters. Using an external oscillator or crystal cleans it right up! I would NEVER put that original VFO on the air and put my call on it. Its am modulation looks fairly clean and it has a pleasent enough tone. It makes 20 watts or so of carrier and peaks to about 100 watts. And it has provision for a high level Plate modulator. But I doubt the internal power supply would have the umph to make it modulate properly.

Not even a good source of parts...

Back in high school I owned two of these bow wows.
The first was a gawdawful disaster that blew up it's power supply, followed by a general meltdown. Good riddence!
The second, I have to admit, was pretty decent; it got me a lot of CW operating time, and even some DX, but this one was FAR from a stock transmitter.
A local, K9ANM (now K9RP) had worked the rig over. The first thing he did was scrap that horrible VFO, and replaced it with a Collins PTO meant for an R-390A receiver!
Essentially, his modified T-150 served as an amplifier for a Collins VFO... and it worked out pretty well!
AM operation... the less said about that, the better.
A few years ago, I encountered a T-150A as part of a gear swap, and played with it a little bit.
Don't let the "A" fool you... the folks at Knight Kit didn't atone for their sins and clean up the design.
All they did was TRY to add 6 meter band coverage and that was a FAIL; trying it into a dummy load on 6, that test was the ONL:Y time I've ever seen a spectrum analyzer start LAUGHING... and I kept puttin' in smaller and smaller Bird wattmeter slugs, trying to find the output!
IMHO the ONLY halfway decent transmitter that Knight Kit ever produced was their first one, the T-50.
The T-150 design isn't worth the cost of the powder required to blow it to hell.

The worst
|
Time owned: 0 to 3 months

Traded in my brand new Challenger kit for this garbage when I got my General in 1961. Built it in 2 days and on the air. Got at least 6 OO reports of FM on my AM signal in less than 2 weeks!!
Mailed back to Allied under warranty but my Challenger sadly was already gone.

Design Needed Work - Had Lot's of Fun!

My dad purchased this as a first xmtr for me at the Harrison Radio Washington's birthday sale in NYC, right after I got my ham ticket. The VFO drifted badly and the chirp on CW was even worse! A local ham came over (I had no clue at the time) and reconfigured the VFO to run continuously when the t/r switch was thrown. That helped the chirp. I built a Heath GR-64 as my first RX...another winner!
Hey, I was 15 yrs old and having fun.
Too bad I cannibalized the T-150; I would love to still have it as a momento. I must honestly give it a "1" technical rating, but emotionally it's a "5"!

Excellent for a fair price

For my 23nd birthday in 1965, my ex-XYL bought one of these new kits for me. I had it built in 12 hours and after another 6 hours of alignment, I had an excellent rig that worked as expected on both AM and CW. I was primarily a CW operator and never had a hint of problems with chirp. The only reason I got rid of it was to trade it in on a nice shiny new National NCX-3 SSB transceiver. Now...that bugger was a real lemon chirper, but I did have a lot of fun working SSB.
Cheers and 73 de W5KD

Bad rig

Time owned: 6 to 12 months

As a brand new general class I built a T150 when they first came out. I was about 13 years old in the 1960s. The VFO drifted badly. On AM the VFO was useable, but on CW it had a terrible chirp. CW with a XTAL had only a mild chirp, but I bought the rig to get a VFO for my new general class ticket. The T150 also used screen modulation for AM. A very poor second to a plate modulated Heath DX100 or Apache. I did make some AM QSO's with it, but got very discouraged with the constant CW chirp reports. I sent it back to Allied Radio. They tried to fix the chirping lemon. They couldn't fix it and neither could a group of electrical engineering instructors at the local college. The T150 was an expensive total nightmare for a 13 year old. In the end my father (K7SAJ now SK) made Allied radio take the thing back for a full refund. Thanks Dad! A real first class LEMON! I would be curious if anyone ever got one to work well on CW.

It Transmitted
|
Time owned: more than 12 months

This was my first transmitter, bought it for $35 used in 1968. Used it for about 2 years, first with crystal control at 75 watts as a novice then "full power" as a general and advanced later.
The VFO would take you on a voyage up and down the band, even after it was well heated and "stablized." Except for an occassional chirp on cw the transmitter worked ok. Used grid plate keying, so one became careful after the first couple shocks from the hand key.
Used it with a Heath GR-64 receiver, so you know I was a Big Gun!
73, Bill
