Re: [IRCA] Tone Testers on 1610/1020 and 590 - Direction Finding-other options

[Milspec390@xxxxxxx]

Mr. J. -

  Yeah. RDF's still useful for finding one's position and inversely for 
shooting lines of bearing - LOBS - to unknown sta's. Good BCB receivers as well - 
sensitive, selective, run forever on D/C cells, usually include 12V car/boat 
jack. 

 Ebay and hamfests good hunting places along w/flea markets, junk shops.

  Best of lot here, Benmar 555A: tasteful late 70's beige & grey. Obtained 
alignment instructions via googling but no need. Dial accurate, sensitivity & 
dynamic range hot.

RDF's include Beacon Band and 'Marine Band'- usually 1600 - appx. 4500 KHz.  
Many have BFO's from glory days of CONSOLAN sta's.

Simpson Aqua Meter: 80's 'hi-tech' Blue & Black w/chrome paint knobs - Yow! 
Slightly less selective than Benmar yet DF bar ever so slightly sharper nulls. 
As w/Benmar, has BFO & RF Gain control.

Portable, Bendix Navigator 400: no-bullshale industrial green: Sensitive, 
accurate, responds well to alignment, be sure to first position DF bar coils. 
Runs forever on 4 x AA's. As w/other RDFs, has real movement 'DF Level' meter and 
RF gain control.

Nova-Tech Pilot II - Manufactured Bendix 400 as well. Preternatural Cold War 
Black case, includes VHF Aero band. DF whips allow you to shoot lobs to 
aircraft. 

Apelco a vintage hi-grade name, posters surely have others. 

Had Ray Jefferson ADF unit, sold some years ago. Motor drive automatically 
pointed DF antenna at station & nulled it. Cool.  Ray Jeff's also hi quality.

 Every serious radioman should have at least one RDF.

Were ours a just society, we'd long ago have been issued them.

                                                                              
                       =Z.=
