Testing Short Wave Operation

The Analyst contains equipment for cnecking the antenna and RF portions of a Broadcast receiver or the Broadcast portions of a multi-wave receiver, but it does not have facilities for checking the RF section for shortwave operation. A device is provided, however, for checking the operation of the short-wave oscillator up to 15,000 kc. If. the set does not function on short waves, the oscillator is working properly over its entire range, and tests on the Broadcast band indicate that the receiver is working properly overall on that band, it is obvious that the failure on Short Waves must be ahead of the mixer tube. With the trouble localized to that extent, it should be relatively simple to locate the actual defect.
