[Repeater-Builder] lmr 900 - duplex noise
I am getting ready to install new antenna on tower with a run of LMR 900 on tower and a run of 1/2 heliax on tower. my question is whether to go with the lmr 900 or the heliax. I have read lots of discussion on duplex noise and duplex noise using LMR 400 does the same hold true with 900? I am assuming it does...
Re: [Repeater-Builder] lmr 900 - duplex noise
LMR900 has the same problem. The issue is any foil/braid construction. Heliax is what you want.

Re: [Repeater-Builder] Need source for UHF power module
I have a number of M57729L which are 400-420. The H is 450-470. These hybrid parts lose gain pretty rapidly outside the spec'd range but will make power over quite a wide range. The L will make spec up to 430 or so an have full power capability at reduced gain to almost 440. Probably not an answer for you.

[Repeater-Builder] HT-1000
I have a question, maybe two on the Motorola HT-1000 portable radio. On the Repeater-Builder's information webpage that talks about how to decipher the model number example: H01SDC9AA3BN The forth digit/letter defines the working spectrum example S for the range 470-520mhz, R 438-482mhz, etc. I am talking obviously about the UHF model HT-1000 Jedi series radio here. My question is,are there model R out there and secondly, how easy or difficult to retune the S model if the range is outside the Amateur Radio arena? Many thanks guys.

You need to read the radio with RSS to determine what actually sub-range of those frequencies the radio is programmed/capable of. Or you can disassemble it and check the parts/modules against a list to see what band-specific parts are inside. -- Kris Kirby, KE4AHR Disinformation Analyst

RE: [Repeater-Builder] HT-1000
Douglas, Your range information is a bit off target. The 'R' range typically operate in the 403-470Mhz range while the 'S' range radios typically operate in the 450-520Mhz range. These radios do not take well to any sort of retuning as you put it but the 'S' range radios can usually be easily programmed into the 440Mhz range without much effort. Read all the info on both the RB website and the Batlabs website to learn more. Oh, and the 'R' range radios are readily available but they're more popular for obvious reasons. These radios are part of a family commonly known as Jedi (Motorola's production 'pet name', all models have one) which includes the MT2000's, MTS2000's, JT1000's, and MTX8000's and 9000's. There are slight differences between all and they don't all share the same software but they do share the same accessories and are built on the same platform. Needless to say there's a lot yet to learn about them.

RE: [Repeater-Builder] HT-1000
Douglas, According to the HT1000 Service Manual, the model number H01SDC9AA3BN breaks down as follows: H - Handheld Portable 01 - HT1000 Model S - 470-520 MHz D - 4.0 - 5.0 Watts RF Power C - Standard Controls, No Display 9 - Channel Spacing is Variable/Programmable A - Primary Operation is Conventional/Simplex A - Primary System Type is Conventional 3 - Feature Level is Limited Plus B - Version Letter is B N - Unique Model Variation is Standard Package Needless to say, your radio is not a good candidate for use at 70 cm. While it is possible to hack the RSS so that you can get the radio to accept 70 cm frequencies, it is quite another thing for the radio to function in the Amateur band with acceptable power and sensitivity, and without burning up the final. Moreover, there is nothing to tune inside the radio; there are significant differences within the radios for each band. Perhaps your best course of action is to sell your radio to someone who needs the S split, and buy an R split radio. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com mailto:Repeater-Builder%40yahoogroups.com [mailto:Repeater-Builder@yahoogroups.com mailto:Repeater-Builder%40yahoogroups.com ] On Behalf Of Douglas Sent: Tuesday, May 25, 2010 8:49 AM To: Repeater-Builder@yahoogroups.com mailto:Repeater-Builder%40yahoogroups.com Subject: [Repeater-Builder] HT-1000 I have a question, maybe two on the Motorola HT-1000 portable radio.

RE: [Repeater-Builder] HT-1000
Eric, Manual 6881200C75 was updated in manual revision FMR-1686-1 to show the splits we've all come to know as 403-470 and 450-520 beginning with radio version B. The 'S' split radios usually take nicely to the 70cm band in my experience using the SHIFT key method in fact, I have two here working this way right now. Subsequent versions of that manual as well as 6881200C40 show the actual splits by model family. 73, Gary N6LRV -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Eric Lemmon Sent: Tuesday, May 25, 2010 7:46 PM To: Repeater-Builder@yahoogroups.com Subject: RE: [Repeater-Builder] HT-1000 Douglas, According to the HT1000 Service Manual, the model number H01SDC9AA3BN breaks down as follows: H - Handheld Portable 01 - HT1000 Model S - 470-520 MHz D - 4.0 - 5.0 Watts RF Power C - Standard Controls, No Display 9 - Channel Spacing is Variable/Programmable A - Primary Operation is Conventional/Simplex A - Primary System Type is Conventional 3 - Feature Level is Limited Plus B - Version Letter is B N - Unique Model Variation is Standard Package Needless to say, your radio is not a good candidate for use at 70 cm.

[Repeater-Builder] PX777 as manpack-repeater
Looking for a way to make Puxing PX777 as a Manpack-repeater Puxing PX777(+) has VOX, with VOX you may use two rados as repeater by connect mic to spk / spk to mic, placing radios away from eatch other in that way it will not interfer with each other! may use duplexer as well here! Do not HAVE to use filters, if radios are placed one on top of other, in about 50 cm over the receiving radio! But, is there a repeatercontroller for this type of use? BOTH RADIOS HAS TO BE SIMPLEX-Opperated!
[Repeater-Builder] quantar repeater setup
Hi all; I am currently deployed to Afghanistan. I received four quantar repeater/base stations for use here, plus 140+ XTS5000R handhelds. I am attempting to setup the Quantars as repeaters on the VHHF1 band, in non astro/analog mode. I have one setup with a separate transmit, and receive antenna. These antennas are the Andrews Omni, Exposed Dipole Antenna type. I am configured for scan mode, using four channels. The second Quantar is configured for one T/R antenna. (Ran out of mounts here for antennas). At first the setup worked well. (I have various models of handhelds using the system, this is why i chose non astro cofiguration.) Shortly after activation, certain handhelds were not able to hit the repeaters. Both are setup for 125W output. It seems after these were put into use, our radio coverage is worse, not better. Is there an option I'm missing in the software config. of these repeaters? I am new at the repeater business. My background is more tactical radio configurations. This is my first time with repeaters. Any assistance on this is GREATLY appreciated.
