Re: [Repeater-Builder] Re: pre-amp placement
Anyone have a spare bandpass filter tunable for the UHF amateur band like a DCI? Thanks! Alan - Original Message - From: Mike Dietrich To: Repeater-Builder@yahoogroups.com Sent: Thursday, November 26, 2009 10:09 AM Subject: Re: [Repeater-Builder] Re: pre-amp placement The main way of thinking is that you want to put the pre-amp after the band pass filter. The reason for this is that if it is before the b/p filter, it amps anything it sees, noise and unwanted stuff alike. If its behind the b/p filter, it only amps the signals that are left and need it. You might need to add a several DB attenuator between the pre amp and the receiver to keep from overdriving the front end. Advanced Receiver Research makes very good low noise preamps as so do several other companies.

Or does it matter? Depends and it does matter... based on how busy your radio site is, where any other rf activity is relative to your frequency, the type of preamplifier, how it's constructed, your receiver front end, your duplexer type with number of cavities, your Tx Power level and a few other tidbits... got a headache yet? I'd venture to say... if your receiver front end is of decent Q (quality) and reasonably narrow band-width along with a decent duplexer... then the preamp might best go after the duplexer, between it and the band-pass cavity. If your receiver front end is average or fairly broad (a few MHz band-width) there might be a case to include the extra band pass cavity after the preamp before the receiver input. Some of this option depends on the duplexer and TX Power Level. The point of what I write above is about trying to obtain the best overload prevention performance and or damage control when the preamplifier is overloaded and generating unwanted signals. Many but not all the variables are are in the list. You could of course try both positions and measure the system performance. s.
[Repeater-Builder] Service Monitor FS
Hi guys, I have a Schlumberger Wavetek 4015 Service Monitor for sale. The unit works fine and is not beat up. It is a Stabilock. I have the manual as well.

Re: [Repeater-Builder] Re: HT750 vs CP200
Personally I think the CP200 Is not a very good radio. The HT750 is decent but the battery design stinks as the release tabs frequently seize and make it so you have to pry the battery off ruining it. There are also the code plug problems on both that make the radio a doorstop until sent back for flat rate. I don't know why but we do see quite a few corrupt codeplugs these days. I like the ICOM IC-F24 For an entry level radio or the Kenwood TK-180 series for a higher tier. Also the motorola PR-860 is a good choice. To me the good motorola radios start at the PR-860. Stay away from the ICOM F-21. That is really a cheap radio and won't last. Sent from my Verizon Wireless BlackBerry -Original Message- From: MCH Date: Sun, 05 Jul 2009 00:15:24 To: Subject: Re: [Repeater-Builder] Re: HT750 vs CP200 I would stick with the GP300s. The CTCSS/CDCSS decode on the HT750s absolutely stinks. You miss the first word or more on them while the GP300s get every syllable. I'm not sure how Motorola lost the ability to design a proper decode circuit, but all of the recent offerings have been weak in the CTCSS/CDCSS (PL/DPL for the purists) department.

Re: [Repeater-Builder] Motorola Mototrbo Repeaters Linked
Mototurbo cannot operate in mixed mode analog and digital simultaneously NXDN can. Mototurbo does not use open standard technology and limits your choice to Only Motorola. NXDN is Kenwood and ICOM and soon others. Mototurbo does not offer 2 Tone paging NXDN does. Mototurbos use of two voice paths on 12.5 does not qualify as 6.25 Khz compliant. Please advise me where in the Mototurbo software it allows you to choose a 6.25 khz emission as I have not seen it.
