RJO
Special: is an engineering prototype of a
general coverage double conversion receiver covering
2 to 30 MHz, it has notch filter, bfo, selectable
side band, vernier tuning, and more. It was built by
Robert J. Orwin, who was a chief engineer at
Hallicrafters in the 60s.
This item has the same footprint as the SX-101 but
otherwise bears no resemblance. |
SX-1000A:
Here is a model shop mock-up, no electronics. The
model number was used for other mock-ups like the
digital SX-115 I already have. This one resembles
the SX-117. Like the digital SX-115, nothing was
ever done with this arrangement. |
