I sincerely hope I'm posting in the correct forum. I'm about to purchase a Motorola xts3000 III UHF and a xts3000 III VHF. I have the CPS programming software but I am wondering specifically if the UHF software can drop it low as 440.000. I am certainly willing to lose the top end at 520.000. Would ...

krazybob

BINGO!!! Awesome reply.

I am not at home with my programming cable and cannot for the life of me remember how to enter FPP mode on the Motorola JT 1000. I seldom use it but my BK was stolen in an auto burglary. As I recall I just press and hold the blue button on the top-left side and goo straight to the password. No dice....

Thank you Steve for seeming to understand what it is to try and learn over the internet. It would be far easier if I had a hands-on Elmer. But this thread is about using the MSF's PA and nothing more. Thank you nonetheless for your kind, polite and encouraging words.

Your advice Doug of using the resources at RB was a good one and I've been there again. Unfortunately, The file you clicked on does not exist or has been renamed or moved. ... ... It is now at http://www.repeater-builder.com/motorola/msf/msf-power-amp.html I hope that this helps someone else in the ...

I really enjoy the excellent users here n come here again looking for advice. We have learned some hard lessons with our MSF 5000's. Our club owns three. They are clearly great repeaters but just can't handle southern California 15KHz band plan spacing. We don't need to go there. The key two things ...

krazybob

Yes. If you lower the TX PA output the transmitter can get dirty and repeat trash. But if the CDM radio has a low power setting an attenuator on it could drop its level. But we're think more of just using the CDM for RX at this point. I am just exploring options. I have three MSF's that I'd hate to ...

krazybob

Hi Doug, I read RB but I like the atmosphere better here. As a newer repeater trustee I have much to learn. I admit it. You have graciously answered my question. In my humble opinion RB isn't so much for new guys like me. I read a lot of arguments. But their research stuff is great if one knows what...

I am new to DosBox. My 386 laptop floppy appears to be out of alignment and I need to use an AMD 1GHz desktop. I use it to program Bendix radios and Windows-based Motorola software. But I have stacks of GM300's (GM300, Radius, M110, etc...) that I need to program. Could you help me along here with w...

krazybob

As we consider options for our MSF's that are 30KHz wide on VHF I have heard that the PA's can be modified for use with, say, a mobile radio based repeater. The In/Out is easy but what of the molex connector? What has to be done? What amount of drive does it need? We have three of the 125 watt PA's ...

krazybob

Thanks guys. I think that I am hosed unless I begin by changing repeaters. It has been suggested that I consider using a CDM 750 for RX only. Being newer it has a good front end capable of 20KHz operation. Its either that or accept that weaker signals may carry the output of other repeaters. I love ...

krazybob

I have three MSF 5000's. One is deployed and two are about to be. We have been struggling!!! But the one already on the air has suffered from interference for some time. It's input is 15KHz from the out of several repeaters. The band plan is 15KHz spacing. Nothing can be done about that. Making matt...

krazybob

I don't see how sniping helps. You have not communicated with them on this topic as I have. For example, the repeater that has been tearing up our input with deviation in excess of 4.2KHz has been told to decrease their deviation to or below 4.2KHz. That was not a recommendation but a policy. You ar...

krazybob

As a moderator I would expect more courtesy from you. :-( With that said, perhaps you choose to ignore the word "install". "Use an audio delay module..." The words "Install" and "Use" are directives instructing us to take action. We have long tails. I cannot t...

krazybob

Well, actually they do. -6 dB IF bandwidth should be no greater than +/- 6 kHz, & -50 dB IF bandwidth should be no greater than +/- 10 kHz. If IF filter retrofit is needed in the repeater receiver, Com-Spec in Orange, CA (http://com-spec.com/narrow.htm) has filters for many commercial-grade rece...

krazybob

Thank you for an excellent answer. We are using new Andrews LDF4-50 @ 100 feet. Coming out of our Sinclair duplexer we have a measured loss of 1.5dB. We are using a Polyphaser and new POS connectors. POS should stand for something else. I really prefer the solder type N connectors but Tessco no long...

krazybob

I agree to a point. Our frequency coordinator has a policy that requires a short or no squelch time. They specifically recommend the RLC-MOT. Our MSF, like most others, has great audio. I am going to hate running it through am external controller.

krazybob

Thanks for the info, Bob. We've decided to add a MICOR-based squelch and an audio delay board. We'd just add the RC-210 controller but as I've mentioned we're doing the Allstar thing and there's no need for it. Thanks again.

krazybob

You're suggesting average hambones get their equipment aligned? As long as it's +/- 2KHz and deviates somewhere between 4 and 8, that's good, right? As Bill accurately writes -- and we did not think this through enough -- when you narrow band you have to control the input or the users will "de...

krazybob

Then you will like this, Bill ;-) It is interesting that after changing the main board our receive increased considerably. Odd. Really odd. But with that said we can get the squelch to open at .225uV although a 1KHz tone could be heard down to .17uV. This is after the duplexer and Angle Linear dual ...

krazybob

Thank you for the link. We've got that and it is helpful. We are seriously considering adding the RLC-MOT.

krazybob

Thank you Bob for the helpful advice. This is why I prefer to come here. I actually do know AND/OR but appreciate you clarifying it. As for the MICOR squelch we located it here: http://www.rlccontrollers.com/accessories.html I definitely don't like the two stage squelch of the MSF. It wasn't an issu...

AFTERMATH: After installing the narrow banding kit recommended by TASMA and experiencing very negative results we removed the board today and installed a replacement instead of unsoldering the crystals. We do not fault TASMA at all and understand that they are doing their best with people that spend...

krazybob

For the record we have setup the squelch using the instructions in the manual. I am now reading on RB that apparently I don't know how to setup AND/OR. Again, we've followed the instructions in the service manual. However, if there is something that we - a team of us - have missed my pride and ego w...

krazybob

BINGO!!! Thank you for finding these. The RLC-MOT was supposed to be offered by Link Communications but they don't have it on their web site and their sales department hasn't contacted me.

krazybob

Let me ask you this if I may. How does one set the receiver squelch and the repeater squelch? What/how is the difference. The Moto service manual isn't really clear on this.

krazybob

Thank you for the advice!

krazybob

You're right on the money, Chris. I emailed Chuck last night and asked that our pair be flipped. He stated that they would have to look at the ramifications but I asserted myself. In absolute fairness, Chuck, Sean and the rest of the new committee are working hard to correct what they can. I have no...

krazybob

Thank you all for your replies. I suspect we might have water in the hardline. When first installed we sealed it well with sealing tape/putty. But this morning receive was terrible. Nothing but popcorn. I'm grasping at straws.

krazybob

Recently while we had our repeater off-site for lengthy work our site vendor pulled our hard line for routing in cable trays on the tower. Previously our SWR was nearly flat as viewed on a Bird 43. Now we have 5 watts returning of 100 watts. 5%. Is this really significant?

krazybob

Gentlemen, this is ham radio and not commercial. The MSF 5000 has (had) excellent audio. Ham radios are designed for 20/25KHz spacing and not 12.5KHz. But because a frequency coordinator chose to squeeze in repeaters by using 15KHz spacing and a reversed pair assignment we have to jump through hoops...

krazybob

Jim, Frankly, NO. We will not get into users radios and set our selves up for complaints of radios that no longer work. We will NOT attempt to get into itty bitty Baufeng radios or even Yaesu, Icom or Kenwood. "You broke the case on my radio. It was PERFECT before you touched it. Now it doesn't...

krazybob

Hardly success. Our repeater sounds like crap. The audio is terrible and stations are breaking up sounding like they are deviating out. They switched to another repeater and sound fine. We may have to put the old filters back in and increase our squelch so only stronger signals can get into the repe...

krazybob

Well, we got the 15KHz rocks installed and so far so good. Audio quality remains excellent, as does receive. We're still getting a usable signal down deep and can now use the Angle Linear cavities and the 17dB preamp. Before you freak out -- I added a 10dB attenuator so actual gain is 1-3dB. Too tir...

krazybob

krazybob

I'm sorry but I see no discussion of AND/OR. Is there another thread that discussed it that perhaps I am not aware of? There were no matches for AND/OR when I searched.

krazybob

I have ordered the 15KHz kit. I apologize for hijacking my own thread. After your comments re: TASMA I thought that the readers would benefit from knowing the true story of what has transpired and perhaps relate it to their own experiences, past, present or future. I also wanted to be on record that...

krazybob

We already have Allstar linking via a remote base and a RTCM off of the repeater site. It works great. But this issue would be easily solved by using an Arcom RC-210 controller on the Motorola MSF 5000 repeater. The RC-210 allows us to turn off the PL before the transmitter drops, as well as it has ...

krazybob

Thanks, Chris. It helps that you know the players and the rules. This issue has existed since 2009 and complaints only caused me to be covered with crap. It was a huge mess trying to get a dinosaur repeater to understand that they may have run all previous tenants of 147.705 off but I am not leaving...

krazybob

You are all well reasoned and know the players except that it is 147.70 v. 147.090 -- Catalina. The radio techs at County insist that this is the solution and that a proper preamp will bring it back up. Perhaps changing the IF filter to 15KHz will help.

Dammit!

krazybob

Now that we have increased the elevation back to our coordinated altitude and location we have a repeater whose output is 15KHz from our input. Our output is 15KHz from their input. It isn't a joy for either repeater. In the past a piezo crystal has been strongly recommended. The question is not whe...

krazybob

Ham radios also hear the squelch tail and they didn't before be lowered the squelch low enough to hear low power or distant stations that a tight squelch was missing. I use all Motorola radios. Ham radios hear the tail as well. The MSF is setup for PL encode / decode. We are using the built-in contr...

krazybob

Our MSF 5000's was just adjusted and the squelch is set at around 35 and can open easily for a HT 70 miles away -- but most stations now have a squelch tail. I can't find a reverse burst setting and we do transmit PL. I don't understand the correlation between the repeater squelch and the receiver s...

We have just deployed another MSF5000 with battery backup capabilities. We have no batteries connected. Each time to repeater's CWID announces we are getting a single alarm beep going out over the air. Prior to making a subtle change we were getting the 1-beef after each user would unkey. 1-beep mea...

krazybob

I fixed it by simply spraying compressed air into the holes. I can now hear a 1KHz tone at 3KHz deviation down to 131dBm. Unusable for sure, but the best of the three that I own.

krazybob

I must be an idiot. I have a second MSF that has poor receive and I cannot for the life of me see how to remove the preselector to blow it out. My past Elmer had it out and back in in 5 minutes. What am I doing wrong?

krazybob

this is been a long road of trial and error. But the missing page of the receiver tuning manual, 4 - 44, indicates that the repeater is set for full clockwise squelch. that normally suffice is for public safety situations. Hams, as it indicates, are more willing to accept lower signal input levels. ...

krazybob

This just in! One of our users discovered and repeated this. If yelling or even talking too loud the MSF over deviates and the audio shuts down. I have never experienced this before. I don't understand it because I checked the OTA deviation at 3.99KHz. Using my Motorola MTS2000 HT set for 4KHz I was...

krazybob

I understand. Fortunately there's nothing below 146MHz. Is there a software app. that will take from the top and give to the bottom?

krazybob

Thank you for your reply. You've given me something to chew on. As for desense it isn't cycling and kerchunking and starting over again without a carrier. One the user drops so does the repeater. In fact, now that the repeater has been moved back to its original home it isn't exhibiting the symptoms...
