Recommend a Used Bird Wattmeter 50-150 MHz?
Hello,
The other thread reminds me that i need a high powered, used Bird power meter. Up to 1000-2000 watts, 50-150 Mhz or more, VSWR too...what models can you folks recommend? Preferably one that doesn't screw up the 50 ohms of the dummy load too much! (check with an MFJ before and after putting the meter in) Birds are supposed to be very accurate, or so i have heard. Any advice or Ebay links are appreciated. Slick |

Any advice or Ebay links are appreciated. Slick From http:http://www.metroactive.com/papers/me...eat-9735.html: I missed Creech but got to hear a tape of the band's performance two days later on a micropowered radio station broadcasting at 91.3FM out of Los Gatos known as Radio Free Lost Gatos. The guys in Creech guest DJed, heckled callers and played the whole of their set along with some of their favorite bands. According to RFLG owner/manager/DJ Dr. Slick, the station has been operating out of a house "buried in the Los Gatos hills" for three years. "I do it for fun," Slick says. "I don't do it because I'm an 'anarchist.' I don't go out and say, 'Kill the cops.' I'm positive with radio." Slick was mum on the wattage but said that 91.3 reaches all of Los Gatos and parts of Campbell. Slick plays classic rock, jazz and "a little bit of Bach" when not turning the controls over to guest DJs like the members of Creech. The station can be heard Sundays and Wednesdays, 8pmĀ*3am. Meanwhile, the next Gaslighter Theater show stars Monkey, Blue Beat Stompers, Steadyups, Lucky Strike and Pigs in Space on Friday (Sept. 5). As always: all ages and five bucks. From http://www.svcn.com/archives/lgwt/05...PirateCat.html Monkey Man stepped into the world of microbroadcasting about a year ago, with his friend Michael Magic at Free-Radio San Jose, 93.7 FM, but had to leave the station after some of his on-air hi-jinks went too far. After that, he started working with Dr. Slick, whose station, Free-Radio Los Gatos, is on 91.3 FM on Sunday and Wednesday nights from 8 p.m. to 11 p.m. "Then Dr. Slick said I should get my own station, so I went down to Fry's and got one of those little radio kits for, like, $30." Dr. Slick gave Monkey Man an old one-watt amplifier, and another friend, Austin Tatious of KKUD 104.1 in Willow Glen, donated a mixing board. Pirate Cat was on the air. ------------- It looks like we can look forward to a bigger signal from Radio Free Lost Gatos (or is it Free-Radio Los Gatos?). No more "all of Los Gatos and parts of Campbell"! Or are you be building FM transmitters and amplifiers for sale? Roy Lewallen, W7EL |

From http://groups.google.com: From: Dr. Slick ) Subject: Length of Coax Affecting Incident Power to Meter? Newsgroups: rec.radio.amateur.antenna Date: 2003-08-11 03:25:37 PST .. . . This is certainly not the case on our bench, which is a problem, because i want to have an approximation of how it will perform attached to the antenna before i ship it out to the customer. A difference of 70 watts is not acceptable. . . . ------------- So, out of curiosity, what does a 1 - 2 kW FM transmitter bring on the pirate market? I'd think it would easily be enough to pay for a *new* Bird wattmeter. But would you be able to deduct it as a business expense?

If so, could we drop by your house "buried in the Los Gatos hills" for a demo of your handiwork in operation, before dropping the bucks for one? Roy Lewallen, W7EL |

Come on down if you want Roy, I'd love to meet you in person too!
But you won't find any FCC violations at my place! No siree! This will be going into a dummy load bedwarmer! Thanks for the free plugs, i don't like to toot my own horn, i'd rather others do it for me. i tried looking your name up too, but nothing nearly as interesting...boring ham stuff! Can you folks recommend a Bird model? Slick |

"Can you folks recommend a Bird model?" Bird Electronic Corporation 30303 Aurora Road Cleveland (Solon) Ohio 44139 (216) 248 1200 Fax (216) 248 5426 TLX 706898 Cable BIRDELEC Contact for a catalog and copies of Bird Technical Series (Watts New From Bird), even if you are not buying from Bird now. There is a wealth of information available from Bird, SWR slide rule, various wattmeter instruction books, application notes, and catalogs. Ask for everything they can send you to help understand their products. Their list of products is diverse. The Model 43 has been around for about 50 years. It shares an instruction book with Models: 4430, 4431, 4521, 4522, 4523, 4525, 4526, and 4527. But, that is not all the models Bird has made or makes. When you become thoroughly familiar with Bird`s instructions, you will necessarily be familiar with how the lines that the Bird is used with work. The literature Bird provides makes learning about transmission lines much easier. Best regards, Richard Harrison, KB5WZI |

Thanks Richard,
Do you use an SO-239 connector to type "N" for the input and output with a model 43? Hopefully good connectors won't affect the SWR. Someone else also recommended model 43 too. I'll be looking... Slick |

I can anticipate your cry for the need of calibration. A used Bird is far from a standard in that regard - especially when you could achieve far greater accuracy with a thermometer and a good load sitting in a bucket of water. I've heard that the Bird Model 43 is very accurate. But, then again, maybe there's redemption in you after all in emulating the time honored Ham tradition of pushing a credit card across a display case. Pretty soon the FCC will only offer a handful of call signs (by region) like K6VISA. Well, it's appropriate that you point this out, Richard. In the sense that the FCC has always sold off the spectrum to the highest bidders: Clearchannel, Time/Warner, etc. Slick |

They have both new and used Bird meters, new and used plug-in elements, dummy loads, etcetera. They might even be within driving distance of you. Bob k5qwg |
