RE: [Repeater-Builder] 10 Meter Repeater
Many of those 3 letter agencies use them as Doug stated not only hundreds of miles but even more. I don't know how popular it is now to use 2 or 4 wire that long but I know of a couple of agency repeater boxes that have what appear to be a CSU connected to them now. Maybe they are changing to a dedicated T1 line and doing a A/D conversion on the voice and controls. Back in the analog days it was common to hear dispatchers from DC or LA on the VHF and UHF federal frequencies. A few years ago a construction company had offices on a wide strech of FL and also on both coasts. Their simple UHF repeaters were connected by telco for a really decent wide area coverage machine. -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] Behalf Of Doug Bade Sent: Monday, August 01, 2005 9:58 PM To: Repeater-Builder@yahoogroups.com Subject: RE: [Repeater-Builder] 10 Meter Repeater I would disagree on the later comment as in the commercial world it would be quite incorrect We have been using telco 2 wire and 4 wire DC control and Tone control lines for years.

Re: [Repeater-Builder] Name that Duplexer!
My vote goes to Decibel Products DB4060. The only thing that looks different from the Decibel duplexers I have worked with is the brackets holding the cavities to the mounting rail(s)... but the brackets shown in your photos are exactly like the ones pictured in some of the (older?)

Wireline from about 1000 feet to a couple of miles ? I don't think so. Sepreation of this distance for 10 meters usually means a radio link. You certainly can go wireline for 10's of miles.

[Repeater-Builder] Re: Name that Duplexer! (notice the non ajustable loops)
Was interesting to see the mentioned duplexer. Notice the non ajustable loop/probe assembly (for insertion loss). Quite the hardware intensive layout... You probably don't see this type of duplexer construction anymore because the loop/probes are now done the same way using a regular loop on a disc mounting method. The current way is cheaper (of course), easier and more flexible. cheers, skipp www.radiowrench.com/sonic Neal Newman [EMAIL PROTECTED] wrote: I could not find the old catalog Tom with the Number But said they were Db products Yes I agree on the 4062's Neal-ka2caf Tom Parker wrote: Mike, Looks like to me you have a DB 4062.

Re: [Repeater-Builder] DeskTrac power supply question
Earlier this week I battery backed up a desktrac here at the house for my aprs Igate. Since I already had a power supply and battery setup, I just left the desktrac power supply unplugged, and lifted the spade terminals and wired them to my fuse block on the way to the battery. Used two sets of wire - 1 for the PA power on the back of the radio, and the 2nd for the smaller wire to the control board under the rf. If I ever want to restore it, I just need to put the spades back on the power supply. The manual I have has very little info on the battery revert option, other than it will only provide 100 ma for charging. I decided the independent system would work better fore me.
