FS CG-3000 Automatic Remote Tuner - as is

[Craig Smith]

I have for sale a CG-3000 Automatic remote antenna tuner.  This unit is functional, and just recently removed it from an antenna that I am no longer using.  I purchased the unit new in 2008 from Array Solutions and it has been working flawlessly since then in my application of tuning verticals and inverted Ls.  It has been installed outdoors at the base of a tree in my back yard.

I'm listing (and pricing it) as "as is" for two reasons.  It has been out in the weather for over 3 years so cosmetically it isn't great.  The label on the top surface, for example, is completely worn away.  Secondly, when I just now tested it in preparation for selling, it seems to only obtain a SWR of 3:1 rather than the speced 2:1 on 10 meters.  Only tested on one antenna and perhaps my K3 SWR metering isn't as accurate on this band.   I've never used it on 10 meters, so don't have any historical reference point.  It works fine on the other bands, matching a 37 ft vertical to SWRs from 1.1 to 1.6 on all bands 80 through 12 meters.   I've used it successfully in the past on 160 meter inverted Ls.

The unit is completely automatic.  It tunes by sampling the RF input, and requires a minimum of 10W and is therefore not suitable for QRP.  I have the tune power of my K3 set to 13W and this has always worked just fine.  It has 200 memories for storing previous frequencies so subsequent tuning is very fast.  Power rating is 200W.  Rated to operate from 1.8 to 30 MHz.  Requires 12 to 14 Vdc power supply.  I've been just running a two conductor cable for this purpose, but you could also use a bias-T on the coax.  Average operating current is 0.5A, but you should have up to 1A available for instances when several of the tuning relays activate at once.  For additional information see www.cgantenna.com and also the eham reviews.

Just now opened it up again and verified that everything inside is in pristine condition.   Absolutely no sign of water intrusion, probably due to the good gasketing of the top cover.

Original owners manual (sparse) is included as well as some additional technical and applications info I've found on the web.  It appears possible to construct a control head to manually initiate tuning via a 3 conductor power/control cable, but I have not tried this.

This unit should provide an inexpensive but serviceable remote tuning solution for many applications.  Not in same league as the upcoming KAT500, however.

Price is $100 via PayPal plus UPS ground shipping.   Shipping weight should be 7 pounds from 80503 zip.
