New VE6QE Repeater Radio

The club has purchased a few Motorola MTR2000 VHF repeaters to replace the very old and aging GE-2 radios that we have been using in all the repeater sites for around the last 30 years.. The old GE-2’s are great radios but the last time we tried to peak one up the capacitors on the xtal multiplier board just snapped off.. These old parts have seized solid on the circuit boards so it is time to upgrade I guess.. These new MTR2000 are not brand new but are more of the latest technology, every thing is set up by a computer and there is really now adjusting of parts anymore.. In order to be able to connect these units into our controllers I had to remove the old J5 interface connector and build a new circuit board for having things isolated between circuits.. This required unsoldering a 96 pin plug and then creating a new circuit board and drilling the 96 holes into it for the plug to resolder into, that was fun I tell you…

In the next few days I will be going up to the repeater site to check for mounting and cable lengths that need to be built. Then after that we will install it and see what happens. Stay tuned.. Skip, VE6BGT.

New VE6QE Repeater Controller Upgrade

The club has purchased a new controller from Link Communications to replace the aging and faltering controller we are using now.

The average user won’t hear much difference when you connect  to the VE6QE repeater but in the background there are better improvements.  Things like the actual programming is easier and there are more radio ports to add more link radios. The pix shows the controller and the new UHF hub repeater mounted in a test rack in my shack for programming and testing. The radio at the bottom is going to be a new link that can connect the CAARC system into the SARA system for emergencies…It won’t be on full time like our other linked repeaters but can be connected by DTMF commands when needed… The only thing that is not shown here is the larger DVR (Digital Voice Recorder) that we are using presently on the existing system.  I hope to have it all ready to be installed at the repeater site in the spring. I will be bringing the controller to the next club meeting so if you want to see it you better show up. I will also be bringing some of the older home brew repeaters we have used in the past to compare old repeater building to the newer ones.
