Hi,
  Just got the new (May) QST and saw a review article on antenna analyzers.
The Palstar ZM-30 is rated for use from 1-30 MHz, but there is a footnote that states"
"** Tunes 0-30 MHz. Usable down to about 0.1 MHz"
The ZM-30 features a  dds synthesizer with 10 Hz steps and can measure complex impedance. Has anyone tried one of these on 137 kHz?

Six years ago, I bought a Complex Impedance Analyzer (CIA) from AEA. At my request they modified to operate down to 100 kHz.
It works beautifully, and is easy to use.
For some reason, it was reviewed in the QST article.
Their newer model: http://www.aeatechnology.com/html/via_bravo.htm
covers from 100 kHZ to 200 MHz
