Repeater-builder: Why?
I swear, after all the time and grief various people put into repeaters,
between the kerchunkers, the noise bursts, the lids, the fights for space, the audio troubles, the attempts to run things on a shoestring instead of real money, the neat gizmos to hang off the repeater and controller, voters, links, programming controllers, phone patches, having to move for various reasons, co-channel machines and users, (both legit and of the "I'm gonna put a repeater on this pair, go ahead and try and stop me" kind who know better, but don't care to be a good neighbor), the space they take up in your basement/garage/whatever, .... I figured out today why we do this thing called repeaters. It's so we can always have something to play with. Now, granted, right now I'm physically tired out after caffeine -induced insomnia, so it sounds like sour grapes. But tomorrow, it'll be : "The reason we do this thing called repeaters is so that we can always have something to play with!! Yeah!!! Life is great!!!!" Chuk Gleason KB4MDZ |

Sounds correct!Ok, thanks John. It bothered me as all the pictures I've seen of the Exec II's don't match mine. Also, are these things rock bound, or are they PLL'd? I can't see any place to put either rocks, or crystal elements? There seems to be a RX and TX adjustment near something that looks like a VCO. Tedd Doda CET packet va3sed@va3sed e-mail lazer@... |

The 6 should indicate 38-64 watts. If you want to compare your model number to the ones for Exec II base stations (some codes are in common) go here: Ray, KD4BBM |

They make excelent repeaters or remote recievers the only weak part is the power

Re: Power for UHF repeater

Cristobal,
I did locate the article I was thinking of. It was a design feature article in the Feb 4th issue of EDN by a ham that works for Maxim. Fortunately for those that don't subscribe, EDN has this article available on line. The URL for the PDF version is: For the Online version: The article is geared towards maximizing the output of a solar panel to charge batteries and presents a good general discussion on the topic of solar panel energy maximization. --Dave * REPLY SEPARATOR * On 3/15/99, at 7:13 PM, Cristobal Inos wrote: From: Cristobal Inos <soni@...>conservation heat.is a factor.

GE Mastr-Exec II VHF base station
Greetings...
This is Gary, W7NTF, in Spanaway, WA. I recently acquired several GE Mastr- Exec II VHF base stations, both of which are currently in the 140 mhz range. They are very clean, handsome rigs, with mic, power supply built in, etc, and have multi-channel capability. Measured power out is about 30W on a dummy load. My question is this: Is anyone using this type of rig for repeater operation? If so, what problems did you encounter? I'm wondering if it's worth trying to build repeaters out of them, or should I bag that idea and maybe think about using them for ham- simplex voice use, or maybe even consider converting them to 9600 baud packet for use on the local TCPIP repeater in the Seattle area? What do you think? Speaking of 9600 baud packet, has anyone put these rigs on 9600? I have a 25w GE Custom MVP mobile rig that easily went to 9600 baud packet and has become the workhorse of my TCPIP station..... Without in depth comparison it would appear as if the MVP and MASTR-Exec II are identical inside except for the power supply and channel board for extra crystals. Ideas? 73, de Gary, W7NTF |

get a couple of gel cell batteries and a solar panel to keep them charged.

Re: Power for UHF repeater
Dave Karr
A linear regulator really isn't the best idea here since power conservation
is a factor. As shown about 50% of the power would be dissipated as heat. A switching regulator should be able to achieve >85% effieciency fairly easily. Of additional interest, there was something in EDN within the last month or so related to maximizing the output of solar panels to charge batteries, can't remember if it was presented as an article or as an application example from Maxim or Linear Tech. One concept presented was taking the output from a single panel and stepping it up to charge a higher battery voltage. I'll dig it up if anyone is interested. * REPLY SEPARATOR * On 3/14/99, at 11:37 PM, Daniel Byrd wrote: If you go with a 24 volt system, no need to bye the 24 to 12 reg for--Dave |
