[Repeater-Builder] Re: FS: GE MASTR2 VHF 100w base/repeater
Hi Kevin: I am new to the world of repeaters and may be in the market for a used 2m repeater. Could you please let me know what you are asking for the repeater, whether it comes with a duplexer, and how easy is it to change the operating frequencies. If you wish to contact me off-list with pricing, etc., my email addr is va3uv(at)rac.ca 73 de Ramesh. --- In Repeater-Builder@yahoogroups.com, Kevin Custer [EMAIL PROTECTED] wrote: [EMAIL PROTECTED] wrote: Wow Kevin, sounds like you got a [EMAIL PROTECTED] repeater with 330 watts on 2meters. Question for you: How many watts ERP is your repeater putting out? What type of antenna will handle 330 watts?

Subtracting the duplexer insertion loss of 1.5 dB (or 29 %), I get about 175 watts to the bottom of the feeder which I lose an additional 1/2 a dB or so, so I really get about 158 watts to the stick (Sinclair SRL-229) which has a rated gain of 6.1 dBd, so my ERP is about 650 watts. The antenna will handle 300 watts, so I'd need to run over 400 watts for that to be a concern. I have run this station for short periods of time at the 330 watt level for testing. There isn't much difference in ERP between the 250 and 330 watt level, so I choose to save on the electric bill and keep the coordinator happy and run it at the 1/4 kilowatt level. Kevin Yahoo!

Hi Ramesh, You must have tuned in late; the repeater I referred to herein, isn't 'For Sale'. I have more in this repeater then most have in 3 or four of them. grin We do however do custom/professional repeater conversions from commercial gear such as the GE Mastr II and Motorola Micor, from either Stations or Mobiles. Go here to view what we have to offer: http://www.repeater-builder.com/rbtip/custombuilt.html ve3rsd wrote: Hi Kevin: I am new to the world of repeaters and may be in the market for a used 2m repeater.

In this station, GE and Motorola are married to give (IMHO) the best operation from one of the most powerful 2 meter repeaters on the east coast.

[Repeater-Builder] Re: FS: GE MASTR2 VHF 100w base/repeater
I knew this question was going to surface, and was going to comment on it in my initial post, but figured I'd not start a battle! Honestly, I have always been a Motorola person (you are either GE or Moto), and my other repeaters are all Motorola. I also have a ton of spares, so it is easier to support the Motorola. I also prefer the squelch action and receiver front end of the Micor, which I feel is better than the Master II. I also have this VHF repeater interconnected with a UHF Micor into an RLC2a, and it just made for a neater installation. The GE gave us good service. We just recently decided to switch over to the Micor while rebuilding our co-located UHF repeater.

NO. No duplexer included. The duplexer would be worth more than the repeater! Has anyone priced a new VHF duplexer lately???
