I bet this thing cost $20,000 new in its day- designed for technicians working on cell sites, but it covers 25mhz-2.5ghz for its handy for all sorts of ham stuff too. Has a really nice antenna analyzer that doesn't only do SWR plotting, but also will do distance to fault analysis to find problems in feedlines, calculate coax loss and insertion loss. here it is sweeping a stock Baofeng antenna for laughs: 
as you can see, the antenna is not nearly as broadbanded as the radio on VHF! It also has a full spectrum analyzer, and a program called RF scout that was used fro tracking down interference. you can even load maps, drive around and it will plot where the signals are strongest or weakest. 
I am still learning it, but it already blows anything else I have owned out of the water. It was listed at $675.00 or best offer, I tossed out a $475 offer and it was accepted! It didn't have a power supply, but I used a universal laptop one I had around, and the batteries were dead as can be but they are easily found laptop batteries. There are others on eBay now- always ones listing at $2000-4000, but sometimes you see much better prices and can snag one. if you look make sure it has the YBT-250 and YBA-250 modules, those are the spectrum analyzer and antenna analyzer, and the RF scout program as these came with lots of different options. |

Ok... now that I'm intrigued... Seems that there are a bunch of different sub models... A, D, H, B, G.... any idea the difference?

It's incredible the test equipment that you can buy today that used to cost as much as a new car.
We used something like that a few weeks ago on our repeater. We tuned our duplexers as well as the antenna. I remember a time when you sent duplexers away to have them tuned. Now, it's DIY. |

I saw a quote for a General Dynamics R8000B…3GHz option, P25 Phase I and II, Autotune for Motorola XTS, XTL, and APX handhelds and mobiles, tracking generator…just under $50k. Made me think about the unit GD gave me…R8000A (the only difference is the B has a 5 dB more sensitive receiver @-140 dBm) that is fully loaded. Autotunes for APX, XTL, XTS, TRBO, NXDN…P25 I&II. Didn't know they got that expensive. |

Yeah, stuff is crazy $$$$ 15 years ago if you told me I would be tuning duplexers in my basement with a service monitor and spectrum analyzer and I would have less than $1000 in all of it I would have called you crazy. Back then we had access, but only through guys who worked in the industry. |

The only reason an R8000 is sitting in my house is because I'm a sales rep for GD. So I get a demo unit. Have been putting it to use though. |
