Brian and All, I have 3 Maxtracs UHF full duplex links that I use. I use 2 radios at each end of the link. The TX Power is set at 10-12 watts out into a 25 watt 10dB pad to get about 1 watt to the duplexer. I get about 600mW out to the antenna. I run these on an modem at 9600 baud. They work great and I have not had any problems out of the radios. I do use a fan to keep everything cool. I can't say that for the power supply. I did have to get a 20 amp p/s and have not had any problems.
It take 4 radios for each link. I paid less than $25.00 for each radio and have about $250 in each link. Radio, power supply, duplexer, antenna and modem. Distance for these links is about 1 mile, thus the low power to the antenna. Only use what is required for communications. 73, Charles Miller WD5EEH ----- Original Message ----- From: "Brian Poellnitz" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Thursday, August 19, 2004 10:05 PM Subject: Re: [Repeater-Builder] Low Power on VHF/UHF Maxtracs > Hi Brian, > > In my years as a tech at a Mot MSS, we were told that most Motorola > PA's perform to spec until about 50% rated power.
