[Repeater-Builder] Slightly off topic
Apologies to Kevin and the group for the off-topic post. Does anyone happen to know what the subband 144.30-144.50 was used for before it was used for the new OSCAR subband?

Re: [Repeater-Builder] Re: Impedance Matching of Power Amplifiers
The worst one ... TE systems. I have even had Motorola PA's that have decided that they do not like a particular antenna system as well as some TPL stuff.

[Repeater-Builder] Re: Impedance Matching of Power Amplifiers
Hi James, I've found many TE amps to be of better quality when compared to other brands. Since they used conventional layouts, reactance problems related to the amp can possibly be corrected. The obvious answer is a case by case examination. cheers skipp skipp025 at yahoo.com James [EMAIL PROTECTED] wrote: The worst one ... TE systems.

[Repeater-Builder] Looking for connectors
Anyone have a surplus, or can refer me to a source, of *75 ohm* type N connectors? I've run my stock dry and need a few. I can use some for RG59 as well as RG11 (either CATV type RG11 or regular RG11). The only place I've found any in stock is Pasternak and they're $12 each which is kind of steep. I could use a few or a few dozen depending on the price. Come to think of it, I could use a few for LDF4-75A too if anyone has any.

Re: [Repeater-Builder] Re: Impedance Matching of Power Amplifiers
My thoughts They may be incorrect, If a duplexer was constructed so that the Inner conductor to outer conductor ratio was constant the length to the tunning rod, you wouldnt have the swr dips. Sure the main part is the proper ratio, but none of the designs take into account the evil impedence mismatch on the trombone at the bottom of the rod. So while the top half of the cavity is 50 ohm, the botom is somewhere between 60 and 85 ohms. Most likely 75 ohm considering materials avalible. The solution of using a solid threaded rod is one way to circumvent this problem, but the materials avalible (half inch) limit the cavity to a relitivly low Q factor. Yahoo!

[Repeater-Builder] Plotting Audio Frequency Response
Ok, I've looked high and low... and come up short. I am curious to see just how good/bad the audio frequency response of my repeaters are. The problem is that I can't figure out a good way to go about doing it. I'm looking for information on how and what to use to check/plot the audio response through the repeater. I would also like some info on plotting the audio response independently of receivers and transmitters. A nice swept response plot is desired... I don't really want to plot it manually. :) The rest of the system is quite happy... so I figure it is time to punish myself and start tweaking the audio side to make them sound their best. Unfortunately, the audio side is something I know little about. Your help is appreciated. Thanks, Lee Yahoo!

Re: [Repeater-Builder] Re: Impedance Matching of Power Amplifiers
skipp025 wrote: This is true, as a former BIG M guy I've sourced my share of problems out. But there are solutions to most of them. If you use the Z-match device, after alignment into a proper 50 ohm termination the duplexer cavities should then be adjusted for min reflected power as described in my previous post(s). I agree with this as long as cabling lengths of any temporary SWR or wattmeter are taken into consideration. This is why I have permanently mounted (Bird) samplers mounted in my more sophisticated repeater installations. This way I don't have to worry about things changing when I need to tune for maximum smoke. Bird has a table that can be utilized, but you just need to insure you add or remove 1/4 wavelength of cable; considering the coaxial length of the sampler. This is also the reason cheap circuit board samplers/swr meters shouldn't be used in serious repeater installations. cheers Kevin, hope to see you at Dayton again (04) And you as well Kevin Custer Yahoo!

[Repeater-Builder] reflected power in amplifiers.
re: the referenced web page. The text on the web page is not an uncommon example, but any reflected or unwanted power comming back to the power amplifier will cause much grief, reactance is just one player in the mix. The key is the mentioned circulator, which prevents (do a degree) and protects from a multitude of sins. cheers skipp Kevin Custer [EMAIL PROTECTED] wrote: Many power amplifiers have matching problems, even those from BIG companies like GE: http://www.repeater-builder.com/ge/mastrIIuhfpacomments.html Kevin Yahoo!
