[TenTec] FS: Mint Argo 509 Station

[DSJKALLEN@aol.com]

All good things must eventually come to an end, and this is the case with my 
beloved Argo 509 station.  As the original owner, I have made the very 
difficult decision to sell the 509 with all accessories (the 206-A xtal 
calibrator, 208 audio filter, homebrew power supply/speaker, and all owner's 
manuals.)

1).  The Argo 509 is truly in like new condition.  It has the large PTO knob 
and corresponding dial skirt.  During a recent visit to Sevierville for a PTO 
rebuild and full alignment, Garland Jenkins (the T-T Argo guru!) discovered 
the original stock 4-pole 2.5kHz xtal lattice filter had a problem, so he 
replaced it with the 8-pole 2.4kHz filter from the current Omni.  Therefore, 
the rig has much improved SSB shape factor and ultimate stopband rejection. 
And, somewhat surprisingly, the sensitivity and noise floor did not suffer at 
all.  The Omni filter must have a similar insertion loss factor to the 
original 509 filter. 

2).  The 206-A xtal calibrator is in mint condition.

3).  The 208 audio filter is in mint condition, and has had the audio notch 
filter from the Omni Series C installed.  Thus, not only does the 208 offer 
the selectable CW bandwidths within the audio-derived AGC loop, the audio 
notch is fully functional within the loop as well.

4).  The homebrew power supply with speaker in also in mint condition, and 
looks as if it was a factory-designed and produced piece of equipment.  Built 
into a matching Ten-Tec enclosure, it includes a front facing speaker with 
Ten-Tec grille, mic and headphone jacks on the front panel, and a red "power 
on" LED mounted in the red circle of the Ten-Tec plastic logo on the front 
panel. 

5).  All original owner's manuals, including a number of the Ten-Tec Argo 509 
QSL stickers as supplied by the factory at time of purchase are included. 

I don't think you will find a complete 509 station as well cared for and in 
nicer condition than this one.  The Omni 8-pole filter and the (IMHO!) really 
well done power supply/speaker, and its overall condition and performance, 
make it a unique and one of a kind 509 station.

If your not completely satisfied upon taking possession, I will refund the 
purchase price, less shipping costs.  I want the new owner to be as happy 
with the 509 as I have been.  And, I will not sell the accessories 
separately.  It will sell as an entire package, or not at all -- sorry.

Price:  $375.00, plus shipping.
