[Elecraft] New Elecraft Product: XG50 Signal Source for KX3 Extended VFO temperature compensation

[Wayne Burdick]

The Elecraft XG50 is a simple 49.380 MHz signal source specifically  
designed for use with the KX3 Extended VFO Temperature Compensation  
Procedure. This procedure is optional, intended for those who wish to  
use the KX3 in narrow-band modes such as JT65, WSPR, etc., on the  
higher bands. (The KX3's normal temperature compensation is entirely  
adequate for all other modes.) The XG50 could also be used for general  
signal tracing of 6-meter receivers that include the 49.38 MHz range.

The XG50 can be powered from 8-15 VDC. It has an RF output of about 10  
mVpp (-36 dBm). Note that the output frequency will not be exactly  
49.380 MHz. After the XG50 is used for temperature compensation, the  
KX3's REF CAL menu parameter should be fine-tuned using a signal at a  
known frequency, such as WWV or other broadcast station.

Available only as a full kit (soldering required), the XG50 is priced  
at $39.95. Assembly should take well under one hour.

For additional details on the XG50, see the instruction manual:
