SHORT WAVE RADIOS - RESTORATION

This includes amateur receivers as well as consumer radios with short wave bands.

RESTORATION

Restoration of radios intended for SW or consumer radios with additional SW bands will include testing of each band and alignment of the radio to manufactures specification. However we cannot guarantee the performance of the radio on SW bands because of the following reasons:

1. Signal Variance

SW reception is influenced by many propagation factors such as time-of-day, local weather, sunspot activity, etc. Even with the best receiver, reception can be spotty  and in some frequency ranges or bands SW reception is greatly diminished for months at a time.

2. Antenna

All SW radios for maximum reception advise an external antenna. Descriptions usually specify 100 foot long wire antennas 20 feet off the ground. Of course nobody does that [very few]. But if you expect to reliably always pick up Radio Moscow then you need to do something like this.

3. Interference

The modern home or apartment is a rich source of RF signals that can interfere with radio reception. Most common is the hash type signals put out by light dimmers and computers. This can be heard as distinct noise patterns on your radio. Even more insidious is RF interference that does not produce an audible noise that you can hear, but is picked up by the radio and suppresses signal reception.
