Desense?

KG4LHQ

Having some issue with the Quantar howl at the end of some transmissions. If you have not heard this sound then please Youtube "Motorola Quantar Howling" and you can hear it very clear and this is exactly what mine sounds like at times randomly. Any fix?!?

KG4LHQ

I honestly do not think the quantar is the problem because the Kenwood 851 did the same exact thing during cold weather, get alittle RF and all was completely fine. I am hoping it is not a coax issue going to the top of the water tower as there is no telling the cost of that replacement.

Being on ...

Hey guys,

My UHF Ham Repeater is a Quantar 25W Repeater going to a 10 IN 200W out Henry Amplifier then feeding to a Celwave 526 series duplexer. The issue that I am having is the repeater is not in a controlled environment as it is in a metal rack cabinet in the middle of a field under a water ...

KG4LHQ

Still looking for help. Would be even better if I could find a pager that would do 443 mhz!

KG4LHQ

Help?

KG4LHQ

Was 151-159 but changed it in Eng mode to the ham band. Just would like to know how to tune or whatever to improve receiving capability or do whatever it is to make it happen.

KG4LHQ

OK, Well like I said I changed it in engineering mode to 141-149 or something like that just trying to get it to receive better.

KG4LHQ

Tried a Motorola Minitor 3 yesterday and successfully changed it to ham using engineering mode, however it appeared deaf. Anyone know how to tune these things to improve sensitivity?

KG4LHQ

Thanks for all thoughts, still exploring the ideas etc.

The repeater covers very well as it is just wanting to patch some receiving issues on the fringes which is very much expected.

I mean a person on a base station can talk into it from Louisville and talk to another person on the West side of ...

KG4LHQ

Yes, all the licenses that I have narrowbanded have been approved with no issues.

KG4LHQ

Hello,

As you know below in other threads of my repeater system, now I'm wanting to possibly install a couple of remote receivers.

This is something I don't know much about but sure I can learn rather quickly.

This is for a ham UHF repeater and just trying to build this to be better.

Anyone ...

KG4LHQ

Thanks for your input Rob.

I am very satisfied in the coverage. I had the option to put up a Fiberglass and actually have an antenna to do so but went with the 8 bay dipole. I don't anticipate any problems

KG4LHQ

Yes sir it is. Base station can get back with some static from South end of Louisville at the same time a base station with 35 watts can get back from the West side of Owensboro.

I'm pleased.

Just wanted to give an update.

Last Thursday; DB-410 antenna was installed at 160 feet and wow what a difference. Still working on range tests but seems to be considerable difference! Thought I would show all a pic of the install.

KG4LHQ

The antenna is shows a 1.3 SWR but again appears to be a 450-460 so that on top of the leaning issue with a skewed pattern is hurting it.

KG4LHQ

Only ideas to chew on ................
Are you guys on this water tower BOTH UHF ? At least in the 400mhz regardless of HAM band and 450 - 470 ? I also never read anywhere what the other guys band was - UHF or VHF, maybe 800 ? I state this as I would not compare a guys coverage at 150Mhz. is going ...

KG4LHQ

Just an update:

Finally have received permission to repair mounts on the tank. Will not be able to install a DB-408 or similar so I went with a commander technologies 1151-2N 8db Omni Directional.

Work will be completed on May 16.

Hey Abbylind,

I have a Cat 300 DX Repeater Controller currently on my TKR-851. Any idea how to make it do that?

KG4LHQ

I seen the specs didnt know if it still would or not lol.

KG4LHQ

The higher tier products (Quantar, MTR, MSF, MSR) had alarm over the air, but it just beeps. All you knew was something broke.

Ritron makes a cheap little box called The Quick Talk Wireless Monitor that has four inputs, and about 30 secs of recording memory - just enough to say "AC power fail at ...

KG4LHQ

What are you talking about Andrew? Ours work great just our local Moto dealer decided to install them incorrectly.

KG4LHQ

The websitr says: Bandwidth Mhz for Less than 1.5:1 VSWR Iis 10 mhz so id it is indeed a 450-460 antenna then it should still work based on the bandwidth range.

KG4LHQ

The antenna was used on 451/456 so would have to assume this make/model is a 450-460mhz UHF stationmaster.

KG4LHQ

Well i've finally been able to determine these are Stationmaster antennas. So my question is which will work better? I know this question is probably related to which is a better vehicle Ford or Chevy but if I can save some expense cost and get a decent coverage repeater w/ this stationmaster ...

KG4LHQ

Trust me, I like the magnet idea but 8,000 just for it is way way out of my budget.

KG4LHQ

The tower climber/company suggested this. I was leary myself.

KG4LHQ

What are the boards thoughts on using an epoxy to mount the antenna ontop of the tower?

KG4LHQ

I have been told that the dipole bay antenna that I have will be easy to get up there so all plans go for that DB-410 to go up there.

KG4LHQ

What is that?

KG4LHQ

Yeah, I would be willing to bet that is my antenna as the other antenna is the road department repeater that I installed as well and it works awesome compared to mine.

I am trying to see if they will let me climb it to see what kind of mount device they have holding these antennas and what I can ...

KG4LHQ

Better pictures looking for ideas... I had considered getting a bracket and mounting it on the tower vent but I see there is a nice cap over that so not sure if that will hurt my idea or not.

Hello guys,

I have secured a DB-410D antenna (I only have the bottom piece that I'm installing) and show about a 1.3 SWR on where it needs to be but now looking at the top of the tower there doesn't appear to be ANYTHING that I can secure it to on the top other then the vent at the center top of ...

The water tower isnt tilted but my phone was when I took my pic LOL!

Thanks Bill. I will get them for you.

Hello guys,

Looking for some discussion in regards to my UHF ham repeater that I am in the process of installing.

The repeater is a Kenwood TKR-851 doing 10 watts going to a repeater amplifier doing 100 watts. The duplexer is a Celwave 526-4-2 tuned with 2db loss to my amateur repeater on 443.325 ...

Pyramid Repeater

1602 & 1604 Filter Tuned to some frequency that the repeater will be receiving.

One filter connects to radio to antenna

Other filter connects to repeater then to antenna.

Get about 2 1/2 / 3 miles out of ours in the rescue truck - I fixed it after our M dealer screwed it all ...

KG4LHQ

I don't know about the rest of the group but I thought Orlando Hamcation kinda lacked today. Definitely wasn't like the last couple years on a Friday in the flea market part.

KG4LHQ

Currently flying right now from Kentucky to Orlando.

Have a great time.

Sorry but I will be carrying a Kenwood P25 LOL

KG4LHQ

Thank you! Sounds perfect!

KG4LHQ

Thanks Tray. Standard 1/4 wave NMO should work just have to trim it down. How much was the license?

KG4LHQ

Wont work either as the input of the main repeater is 153.755. Both surrounding counties needed their input is around 159.070/158.945

KG4LHQ

They need to get one as high as they can as the neighboring agencies transmit into the repeater is 159 mhz... Any suggestions?

KG4LHQ

That antenna is for the vehicle repeater SVR-200N tuned for 2 watts power output. The radio is a XPR4550

KG4LHQ

So if you guys remember a while back about the issues with the vehicle repeaters, now I am starting to work on the officers cars and their worse then the fire. They are using 1601 filters that require 5 mhz seperation and their tuned to 158.805 rendering most of the public safety useless. I have ...

KG4LHQ

Another screw up on the radio shop behalf. No studies!!! How hard is it to get a high freq license?

KG4LHQ

Ok so now another issue has came up.

The police cars are running 1604 and 1601 filters, the 1601 filter is good for 5mhz seperation. The stupid radio shop decided to tune them for 158.805mhz so essentially knocking out any spread right in the heart of that spread where most repeater inputs This has ...
