This is the Lafayette HA-410 (Pictured is the identical 6 meter version, the HA-460), a single band 10 meter tube-type AM ham transceiver. This model radio was originally made in the late 1960's. It featured Volume, Plate and Load controls, a large S/RF meter, and separate independently tunable transmit and receive VFO's. You could also select crystal controlled transmit from a switch connected to a front mounted socket. A spot switch allowed the operator to synchronize the transmitter with the receiver. Power output was about 7 watts dead key with about a 28 watt peak modulation from a single 2E26 tube. Frequency range covered from 28.0 to 29.5 Mhz.
But the most appealing feature of this radio (and why it's included on a CB page) was the ease at which it could be moved down to 11 meters. A simple change of the fixed tank capacitor in both the receive and transmit VFO's was all that it took. I originally had mine set to run from 26.000 to 27.500 Mhz. This fairly broad coverage was nice, and I used this radio exclusively as my "down" radio, as it could drop lower than any of my other radios at the time (Late 70's). There was some VFO drift, which became manageable after the radio was on for an hour or more. Operating this radio pretty much required having a frequency counter handy, if you wanted to know exactly where you were. Transmit audio was strong and punchy, and with no internal modulation limiting, it was fairly loud as well. The receiver was sensitive with a nuvistor front end, and selectivity was also fairly good. One annoying aspect of this radio was the lack of a squelch control. This left you at the mercy of the static and noise which was often high on the channels. But when running way down below channel 1, the noise was not usually all that bad.
I picked up my HA-410 from Steve, and I ran it for a few years, before selling it at a hamfest in the early 80's. I still see the 6 meter HA-460 radios from time to time at hamfests, but I rarely see a '410. It was certainly the less popular version.
