Novice Bookends

Many identify the Novice Class between 1951 (when it was introduced) and the early 70s (when VFOs, 250 watts and renewable licenses became part of the novice license) as the golden or classic era for novices. During the 50s and 60s the novice class was clearly a learner class. During this time amateur radio manufacturers marketed rigs specifically designed for novices.

I have two that I would call bookends to this classic era. One is the Hallicrafters SR75 introduced in 1951 just as the Novice Class was introduced and the other is the Heathkit HW16 (1967-1976). Both of these are transmitter/receivers in the same case with features and capabilities that match the restrictions of the

Novice Class. Hallicrafters chose the add a crystal oscillator to a S38B along with circuitry using the 50L6 audio amp as the transmitter final. The resulting rig looks, from the front, almost exactly like a S38B. Performance and usability would have been disappointing.The transmitter was only rated for 10 watts and changing bands or the crystal required removing the back of this AC/DC set. Also the SR75 receiver section was basically a S38B, an entry level receiver that many beginners would already have had. In addition the price delta between the S38B and SR75 was $40. Several crystal controlled transmitters were on the market in the early fifties in this price range that would have looked better to the novice and he could build his own transmitter even cheaper. By the time Heathkit tackled this particular niche in the mid 60s they designed a rig from the ground up that had features better tuned for the novice.

Two bookends on an era but Heathkit did a better job. I'm using my HW16 while the SR75 remains a shelf queen good for discussion.

A New Rig

My new rig...

The Heathkit HW-16 was one of the last rigs designed specifically for the US Novice operator. It was marginally a transceiver. The receiver and transmitter sections share a common power supply and antenna coupling circuitry. The HW-16 covered only 80, 40 and 15 meters, the bands allowed for Novices in the late 60s. The CW only transmitter ran 75 watts and was crystal controlled, again novice requirements. The receiver section was double conversion with 500Hz selectivity. Good selectivity for the chaotic novice bands was a must. After my initial tuning around the 40 meter band I'm pretty happy.

Only 345 +- days to go to the NRR 2019. In the mean time look for me in the evenings around 7110-7120.
