What to Know About Hammarlund Receivers
Hammerlund radio receivers were manufactured from 1910 until 1973. These receivers let you receive short-wave and ham radio signals. These receivers can be modified with various audio equipment as well as external antennas, and many affordable options can be found on eBay.What kind of products did Hammerlund produce?
The Hammarlund Manufacturing Company manufactured a number of shortwave radio receivers as well as transmitters and other auxiliary radio equipment. The shortwave radios came in a number of models that could receive a range of frequency signals. In addition to these products, Hammerlund also produced a number of "village radios" for use in developing and third-world countries.Do the receivers require any extra equipment?
A Hammarlund receiver may require an auxiliary antenna in order to receive weaker radio signals. These antennas can be attached through the input ports located behind the receiver. All receivers will also require a power source, usually an AC 110-volt plug outlet. In most Hammerlund units, the receiver will come with a 110-V plug. Certain units may be incomplete and require specific parts in order to operate normally. Additionally, you may also need to get the manual separately which may not be included with the hardware unit. Check on eBay for these Hammarlund needs.What are the frequency ranges of the Super Pro Receivers?
