Re: [Repeater-Builder] UHF Duplexer Question
I have had good luck with the TX/RX brand as well, even at 250 watts with a gasfet preamp. You should have no problem tuning a used TX/RX duplexer from the 450-470 version to the 440 band. I have several of these and they all work good. Leon-N2HLT http://www.expage.com/n2hlt [EMAIL PROTECTED] wrote: I currently have a UHF MTR-2000 repeater, I bought it without aduplexer.

[Repeater-Builder] R100 PA blown
Hello, I am having trouble finding an m2519185 or a cross-reference. From what I cal tell I think the mrf654 or 653 might work, but I am working blind for I don't have a schematic. Which brings me to my next question. Mounted on two of the transistor pins was a surface mount component. I think it was a bias resistor from my limited knowledge of PAs. Can any ID the surface mount. I can't find a datasheet on the m2519. Any help would be great. Thanks, Jason Mathis KD5TJO Yahoo!

Re: [Repeater-Builder] UHF Duplexer Question
Joe, I recently installed a complete MTR2000 UHF 100 watt repeater for my employer. The duplexer that came with the station was a Motorola TLE9022, which is a premium version of the RFS/Celwave PD526-4-2. This is a six-cavity duplexer that is specified at 120 dB isolation, minimum, and 1.3 dB insertion loss, maximum. I confirmed by testing in my shop that it met these specs, which are very good. The MTR2000 UHF 100 watt PA comes with one built-in circulator, but I ordered the station with the "triple circulator option" which adds a shelf containing a dual isolator and a low-pass filter. The primary load on the additional isolator has a thermistor which connects to the station backplane, so that the power will be reduced if excessive reflected power is detected. In my opinion, you can't beat this combination. It is not easy to find high isolation and low insertion loss in the same duplexer. Moreover, some manufacturers claim higher performance than they deliver. 73, Eric Lemmon WB6FLY Yahoo!

Re: [Repeater-Builder] UHF Duplexer Question
I have discovered the manufacturer will tune the duplexer so it meets the company specifications - but won't necessarily tune for maximum performance. As Eric mentions below, he checked the duplexer for expected performance. Neil Eric Lemmon wrote: > > Joe, > > I recently installed a complete MTR2000 UHF 100 watt repeater for my > employer.

Re: [Repeater-Builder] UHF Duplexer Question
If you want to move a TX/RX used commercial (450-470) duplexer, you should order the cable kit from them to be able to maintain good specs. I moved one from 460.??? to 441.5 and it wouldn't make specs with the shorter harness. I ordered the longer kit and it tuned up great.

[Repeater-Builder] Help in locating a DB-408 for the ham band
As per recommendations on this group I have settled on a DB-408 for my new UHF repeater project. My problem is I keep running into dead ends in locating one, new or used, to buy cut for the ham band. I talked to Andrews to see if I could persuade them to build me a one- off for 440 but hey wouldn't. Can anyone help me out before I have to settle for a "stick" antenna? I have also looked at the Maxrad open dipole model which I can get for 440, but it seems like a bad deal, its as much as a DB-408 new. The Sinclair is just too much $$ for th budget.

Re: [Repeater-Builder] Help in locating a DB-408 for the ham band
You can also look at Telewave. They make one similar to Sinclair, but less expensive. However, I have yet to see one of the Decibel 450-460 versions that didn't work just fine in the ham band. I'm running that band split and my repeater is on 442.75. No problem at all.

In my humble opinion, they are a nice little radio and should do a good job. This, of course, will be proven or disproven in due time. Here are some of my observations: The heat issue can be a problem. Turning the power output down only adds to the heat problem. Instead, I took Kevin's (and others') advice and pulled and bypassed the final. The radio does about 3.5 watts this way. The output is very clean (I looked -70 dB and didn't detect a thing) and stable. I observed this into load with a 1:1 SWR as well as a 2.5:1 SWR. Aside from the (still) moderate heat produced, there were no detectable problems during a 35 minute keydown period. To overcome the heat issue, I simply added a computer processor fan to the back of the radio pair that triggers on from the receiver's COR (or tone squelch) and shuts off one to two minutes after the carrier or tone drops. (See Kevin's web site for the circuitry) My radios didn't display any significant drop in power until I tuned down around the low end of 433 MHz. The 16 pin connector has descriminator output, mic input, and PTT available on it making interfacing quite easy. The one drawback I have detected is the built in Tx delay. When added to the inherrent delay from an aftermarket tone decoder, which I am using on the VHF receiver married to this transmitter, the overall delay borders on the undesirable. I have a GM300 service manual and schematic en route, but without it I haven't determined a work-around. I suspect this delay is intentional and can be altered through minor component or circuitry changes. I hope this helps. Good luck. Scott Madison, WN1B Yahoo!

The output is very clean (I looked -70 dB and didn't detect a thing) and stable. I observed this into load with a 1:1 SWR as well as a 2.5:1 SWR. Aside from the (still) moderate heat produced, there were no detectable problems during a 35 minute keydown period. To overcome the heat issue, I simply added a computer processor fan to the back of the radio pair that triggers on from the receiver's COR (or tone squelch) and shuts off one to two minutes after the carrier or tone drops. (See Kevin's web site for the circuitry) My radios didn't display any significant drop in power until I tuned down around the low end of 433 MHz. The 16 pin connector has descriminator output, mic input, and PTT available on it making interfacing quite easy. The one drawback I have detected is the built in Tx delay. When added to the inherrent delay from an aftermarket tone decoder, which I am using on the VHF receiver married to this transmitter, the overall delay borders on the undesirable. I have a GM300 service manual and schematic en route, but without it I haven't determined a work-around. I suspect this delay is intentional and can be altered through minor component or circuitry changes. I hope this helps. Good luck. Scott Madison, WN1B Yahoo! Groups Links Yahoo!

Re: [Repeater-Builder] Help in locating a DB-408 for the ham band
does anyone else run the 450-470 version on the ham bands successfully? My machine will be 441.850. Thanks for all the replies so far!!

They make one similar to Sinclair, but lessexpensive.However, I have yet to see one of the Decibel 450-460 versions that didn'twork just fine in the ham band.

[Repeater-Builder] Re: Help in locating a DB-408 for the ham band
Tom, I'm not sure of the exact model number... but I do have a ham band designed and spec'd decibel UHF dual 2-section 408 antenna. The model with two 408's stacked and it's a real nice monster. Do you need the measurements for the harness or some other item spec? I'd sell it, but shipping would be expensive, so a pickup in Northern CA would be the most practical answer. Email me direct if you're interested. cheers, skipp skipp025 at yahoo.com Original Message - > From: "tgundo2003" > To: > Sent: Tuesday, October 05, 2004 11:43 PM > Subject: [Repeater-Builder] Help in locating a > DB-408 for the ham band > > > > As per recommendations on this group I have settled > > on a DB-408 for my new UHF repeater project.
