I've only got one shelf full and a 3 foot stack on CB stuff.
Here's a look at my microprocessor museum: http://www.geocities.com/scott_unit_69/olduProcs.jpg |

Not sure if he owns the property up there. I am assume it's much more difficult to get heavy equipment up there. Vinnie S. how much could a heavy lift chopper cost to rent? then run say 600-800' of rg-8x to the shack. piece of cake one would think. not. If you read his website, those hills are causing a problem. Some of the beams are blocked from Asia. Vinnie S. didn't bother getting to far into his site. i can see his point though. |

I have one bolted to the back of my 148 to keep the output transistors cool. I'm trying to think of a good spot to mount a pair to my 2 pill without the blades interfering. |

Here's a picture of a couple of mounted fans: http://www.geocities.com/scott_unit_69/fans.JPG My other IC-2100 has a fan just like the one on the left. When contesting at 50 watts in the summer, you _NEED_ cooling! |

When contesting at 50 watts in the summer, you _NEED_ cooling! My heat sink fins are three inches deep. I'm thinking that I can take my dremel and cut into the fins so the fan or fans will be inset and out of harms way while still protecting the unit. I use mine at less than the maximum power anyway so I don't have heat problems in the house, but during the summer in the truck the temp can get up there in a hurry. |

I use mine at less than the maximum power anyway so I don't have heat problems in the house, but during the summer in the truck the temp can get up there in a hurry. I find one minute of AM makes my amp hotter then 5 minutes of sideband. The radio on the left runs FM. That's a constant 5, 10 or 50 watts. I wish it had another mid power setting at 25 watts. Sometimes 10 isn't enough and 50 is too much. It's also been modified to do MURS. The 667 has a few fins pushed over to grab the course pitch screws in the lower mounting holes. The finger guard is attached to the upper holes. That amp is strapped and will draw a good 90 amps, about 1,250 DC watts! That fan turns on when the power button is depressed. I switched the one on the Icom. I'm a real good sandbagger sometimes and cold air will blow after a few minutes of shutup time. |

Sometimes 10 isn't enough and 50 is too much. It's also been modified to do MURS. I would get rid of either the 5 or 10 watt setting (my choice would be the 10 unless that's what you use to drive the 667) and set it up for 25. The 667 has a few fins pushed over to grab the course pitch screws in the lower mounting holes. The finger guard is attached to the upper holes. That amp is strapped and will draw a good 90 amps, about 1,250 DC watts! Yeah, I remember my 667, it would dim the headlights on AM. That fan turns on when the power button is depressed. I switched the one on the Icom. I'm a real good sandbagger sometimes and cold air will blow after a few minutes of shutup time. I was thinking that you could turn it on/off thermally, but the less you add to it, the less that will go wrong. |

Wasn't sure if you had converted it to operate on other bands. And not being a ham I don't even know the wattage limitations on I think you said 2 meters. |

The pills are only good to 30 or 50 MHz depending on the part number. The broadband transformers limit it even more so. I should take a picture of the inside of this busted HTX-212 and this 2 meter amp so you can see the difference in RF circuitry inside them. |
