Bump
I need this soon...... high split.

n5tbu

I need a low band codeplug so I can verify that I did indead hex edit my software to allow entry of 50-54 mhz freqs.
Can anyone help? My email addy is"

Thanks,

That's the thing tho...I don't wanna hack into the harness,I wanna go to the fuse panel like we did in the old days!
The fuses in the cab have no voltages (are they fusing grounds) and the panel under the hood are all hot all the time.
Maybe a spare connector under the dash with Ign available?

n5tbu

I was not able to find a point to tap for Ign sense anywhere on this truck.
I don't want to tie in behind the music radio,any one solve this problem?
Mark

n5tbu

Where??? insert a link,please!

n5tbu

What is ridiculous is, we spent our money an a supposedly excellent piece of equipment,and we can't get tit o work on our freqs,WTF,Motorola? is it not my [I can't read the rules] radio? You will do the freqs I say you will,dammit! Get a fing clue you idiots.

Sounds like lowband RF getting into the pyramid,like usual,lowband gets into everything! Try tuning the lowband antenna for a near perfect match....the dummy load might be a good test.
Also could be that the lowband radio has a harmonic at the Pyramids input freq.

In Louisiana,they have discotinnued DC circuiits unless you are an existing customer...or a Public safty org. Really glad to know the phone companys problems are everywhere,I thought it was only me having the problems. Oh and if you tell them you found more than 10db of loss with your Simpson 260......

n5tbu

The line driver card only drives audio in the phone line,the dc card handles the plus and minus currents that do functions to the station. The polarity is important! If I remember correctly,+5.5 Ma keys on F1 and -5.5 Ma is a monitor condiction,but I also admit to being rusty on DC control! I should...

I have a lowband super consolutte I could donate if you pay shipping,not rail road but the look is the same,
mod

n5tbu

Looks like a Mocom 70 consolette.

n5tbu

You need a KRA-21,it comes full length with a cutting chart.
mod

n5tbu

The 2160 does have an overwrite password,and if that was programmed you can't overwrite to it.

Will,no disrespect intended......I never saw any docs on the cable length needing to be anything specific.I have been using this antenna for 30 plus years on 144-174 and also 420-512. The tessco part number I gave is for antenna only,no cable,I opened a package and read everything....no reference to...

n5tbu

Usually,yes.
mod

n5tbu

AS did redesign the base,it now looks like an AS coil base......I prefered the nylon original!
Tessco part number: 461029

I see that most comments on this subject are from shippers.
I would like some input fron the recievers of all these packages. What ever happened to "the customer is right"
mod

n5tbu

I receive ALOT of packages.UPS is by far the leader,USPS is a joke,and FedEx is second to USPS. Based on that,I ONLY ship UPS. Price is not an issue with me but prompt delivery is! I have noticed UPS has routes,and I always have the same driver. FedEx always has a different driver,and sometimes has ...

Not a 1/4k! Will was correct on his ID
I already found a buyer for the VHF Limited.

n5tbu

Thanks Will,that confirms what I thought I remembered!lol
I have no use for them,but hate to just toss them.

This has been dragging around my shop for years,anyone know exactly what they are?
Thanks,

If all you have is a service monitor,here is a crude test for desense: Put a telescoping antenna on your generate port of the monitor,generate a signal with no pl/dpl till you hear it on the receiving radio,key up the transmitter with a local mic,if the rec goes deaf,you have desense. Yes there are ...

n5tbu

I have a lowband customer whose beacons created rf hash,try taking the ant coax off the radio.If it goes away it is RF,if it doesn't then maybe a filter will help.
mod

n5tbu

Sounds like it was programmed with hacked software,if so,you need that same hacked version..
mod

n5tbu

I tried programming narrow and wide for that test first......not the 455's.
I did see that larger IC but was hoping it was something else! I wish I had some voltages to compare it to before I attempt to change that IC. I really hate to be a "parts changer"tech!
mod

n5tbu

No,I injected in the area of the 455's.
Does the book give typical voltages of the reciever IC pins?
I am suspecting an open trace or plated thru hole,do to the vibration from the tractor it was on.
I do appreciate all the help!
Is the rec IC the 14 pin with "14066b" on it?

mod

n5tbu

I tried that also....nothing!
mod

n5tbu

The 44.395 xtal is oscillating rather strongly. Still no receive with the IFR on
highest setting.
mod

n5tbu

Thanks Jack,I will look into that wednesday morn,44.394??? weired IF! No wonder i MISSED IT!.
MOD

n5tbu

Yes,it does transmit fine......it is for a customer,so if I can't reair it,I need to keep it for spare parts for them.
mod

n5tbu

I don't have it in front of me at the moment,but it was the crystal behind the vol control layed on it's side and the case soldered to the board.
I have typical small shop equipment.
mod

n5tbu

Thanks,I should have mentioned I had changed that crystal but still no receive.
mod

n5tbu

No schematics here,radio transmitts but no receive,has audio.
Any common problems to look for?
mod

n5tbu

Mike,how low will yours go after the mod? Did it keep the 8 meg wide split?
mod

n5tbu

I have 2 out of 6 working on 52.525,the others won't lock there,the vco module needs some adjustable caps to do it right,or you can guess at the values based on the 3 splits info.
BTW the p200 lowband is an MT1000 in disguise!
mod

n5tbu

"That's the wrong RSS for the low band radio. That's the exact error that you receive when you use any version of MT1000.exe RSS on any low band radio, it will let you edit and write to the radio but it will not function at all." I have not found that to be the case,I use mt1000 software a...

Who the hell cares?? One of the most intermittant radios in the moto junk list!
Remember the mostar?

Duracom switcher was my cure as well!Who cares if I cannot get 150 watts on lowband at 15 volts if I can get rated 110 on 13.8!

Many thanks again, Will!

I also need Mic Hi and PTT......I dont have a book,and am working on a project.
mod

n5tbu

Also,I have seen consoletts offshore that had 25 volts on them for a week before a tech could get there...never saw any damage! Repaired the PS and all worked fine.The Mitrek is one of the most "bullet proof" radios ever made by Motorola.

Casey,keep in mind ,some of us are real technicical by nature,and any chance to talk about something we believe in,is gonna sway a little.

"So if I use the radios on a frequency that is 1mhz different, it will fry the radios? "

Yes! A duplexer is tuned to keep the transmitters power from reaching the reciever,it is a very narrow window at the tuned freqs.and 1 Mhz away is too far.
