[ARC5] Model 19 MKll

[Donald Sanders]

Back in 1956 while in High School our radio club advisor, who taught mathmatics and Radio theory class, got a model 19 for the club. I took the task to get it on the air. We had no manuals just the unit and power supply. I quickly found out about the key voltage and traced the wiring to find out why. Then promptly installed a keying relay with low coil voltage to the key. I traced most of the wiring just to find out how it worked. That was practice for many other "reverse Engineering" jobs later.
I was very happy to make contacts with that old girl, almost QRP but lots of fun. Yes, I got an A in the radio class.

I own a Wireless Set 19, Mark II. The "B" set is a rather useless SUPER regen or "rushbox" as some hams call it. I find it utterly useless. The "A" set can be made into a very nice 80 and 40 CW rig. The 807 grid modulation makes AM less than useless but again, a nice CW rig. The screen grid voltage on the key is very dangerous and should be rewired to 807 cathode keying. The original keying is a non-starter and a real shocker, literally. Hi Hi!
