[Repeater-Builder] Re: GMRS HT recommendation?

[ka1jfy]

Something to keep in mind, is that the GP68 [and their chinese clones] are not 
legal to use on anything other than ham in the US.

And, because it's also illegal to import them, they may be seized by Customs, 
with no recourse.

[Repeater-Builder] Re: Desense with Notch-type duplexers - Questions

[tahrens301]

Hmmm,

Well, I did the signal injection into the receiver's port, as
opposed to at the dummy load, and indeed, I do have desense
when using the dummy load.

I guess that points back to the cans & how well they are performing
(or not)!

[Repeater-Builder] Yaesu Vertex 3000U problems...

[Mike Morris WA6ILQ]

I have a Yaesu Vertex 3000U radio here that has programming
problems - when the cable is plugged in to the mic connector it
displays CLN as it should, but won't program.

Does anyone have the pinout/wiring diagram for the cable from
the VPL1 (yaesu's version of a RIB) to the radio ?

If it's a problem internal to the radio, it will be in the path from the
mic jack to the microprocessor... does anybody have the service
manual or at least a schematic and a PC board layout?

Thanks in advance.

[Repeater-Builder] Re: Desense with Notch-type duplexers - Questions

[tahrens301]

I checked it into a dummy load (with one of those celwave
signal insertion boxes), and didn't see any signs of desense.

A friend of mine who used to work for Mot said that he had a
desense problem with a VHF Quantar - Mot sent out some kind
of memo that said you had to use some special kind of duplexer.

But figured I'd ask around here.

Thanks,

Tim

Re: [Repeater-Builder] Re: Desense with Notch-type duplexers - Questions

[DCFluX]

Yeah, I understand VHF quantars or supseptable to something called
'quantar howl' which is digitally delayed desense.

http://www.youtube.com/watch?v=SRfvh0UTFHw

The hypnotoad also has the ability to make the same sound

http://www.youtube.com/watch?v=kiVYjRbZMe0


I've never owned one so I cant put too many conclusions together about
what causes it.

I saw the back of one at a ham fest and noticed the wire ties and
thought that was the dumbest thing I've seen Motorola do.

My next guess could be that the switch mode power supply runs at
600kHz. anyone got any schematics?

Also check if you have desense into a dummy load, could be another
600kHz noise source close to your antenna.

Hi Dcflux,

Yeah, I did that 1st.  Actually, they now come out of the
front of the box & are as far apart as I can get them.

Cut the wire tied together TX and RX cables on the back of the quantar
and seperate them as far as possible.

Re: [Repeater-Builder] GMRS HT recommendation?

[Scott Yeager]

I have a few Motorola GP68 FPP Radios I got from China/Ebay.  They're great
little radios and around 70$ shipped each.  Have both UHF and VHF models.

http://cgi.ebay.com/Motorola-GP68-UHF-430-470MHz-2-Way-Radio-Accessories_W0QQitemZ170368673788QQcmdZViewItemQQptZ2_Way_Radios_FRS?hash=item27aac3a7fc&_trksid=p3286.c0.m14

The battery they come with isn't very good and its NiCd..  They won't last
half a day with constant talking,   But you can get Nickle-metal extended
batts off ebay for cheap.

[Repeater-Builder] Desense with Notch-type duplexers - Questions

[tahrens301]

Hi Folks,

Guess it's a good thing the antenna party didn't happen yet.

Put the DB-224 up on a pole here attached to a portable building.

Ran the 7/8" heliax from the antenna into my garage - about 100'.

With a signal source from my monitor, the repeater would chop in
and out.  Ugh-desense.

I am using an old DBproducts 8 cavity notch-type duplexer. 4 on the
receive, & 4 on the transmit.  The transmit side also has stubs.
(see old thread).

First, I used my spectrum analyzer & sweep gen, and got what I 
thought were pretty good notches in the right places (depending
if I was working on the xmit or rx side.  According to the
analyzer, the notch was about 70dB below the high point.  However,
I think that it was seeing the floor of the analyzer, not the real
notch.  

Then, I hooked up a signal generator on one side, and a receiver
on the other side, and tweaked a bit more for the least signal.

All looked pretty good with definite notches, but it's obvious 
there's desense.

All cables are double shielded.

The system is 147.10/70, running about 60 watts out of the
Quantar.  Even running with battery-backup (20 watts), there's
still some desense.

Could it be that these cans are just not enough, or am I doing
something wrong.

Thanks!

Tim

[Repeater-Builder] MSR-2000 and External Controllers - Repeater - Telephone (auto-patch)

[skipp025]

MSR-2000 and External Controllers - Repeater - 
Telephone (auto-patch) 

How you connect the Interconnect (Telephone Auto-Patch) 
depends a lot on how the device is designed to operate. Some 
devices are made to be inserted in series with the audio 
and COR/CTCSS logic like an external repeater controller. 
Of course there are a number of methods to connect an external 
controller to an MSR-2000 Repeater/Base Station. 

Some Auto Patch Interconnects are designed to be "tacked 
onto" a Repeater or Radio. I would suspect the Zetron 30 
to be this type of device, but checking the manual installation 
information is the best way to go. 

Hooking the Zetron to the Repeater/Base Station depends on 
how you operate the MSR-2000.  Is it an original MSR with 
all the Modules in place or has someone jerked them out and 
gone with the back-plane external controller method?

Gervais,

The unit name is actually spelled "DeskTrac" because it normally contains a
MaxTrac radio. A picture of a DeskTrac is on the RBTIP here, about halfway
down:

My DeskTrac weighs about 15 pounds.

Re: [Repeater-Builder] GMRS HT recommendation?

[n6lrv]

Don't know about the F40GT but the Icom IC-F40LT had front panel programming 
capability, so did its VHF counterpart the IC-F30LT. Versions with high serial 
numbers (above 3 if memory serves) were wide and narrowband capable. I 
still have one of each new in the box stowed away along with accessories and 
software. They were built tough and work fine. Some time ago I scanned the 
keypad programming guide into .pdf and it's been floating around the internet 
ever since. If anyone is interested in both of these radios and their 
accessories & software contact me off the reflector.

Also, let's not forget there are lots of FPP capable UHF XTS3000's and 
XTS5000's around today as well that work great on GMRS.

also what is the encryption type rolling inversion, fixed inversion or DES? i'm

Can these be used in modes other than FM? such as AM or SSB?

The 4530 service manual is downloadable as a PDF from
the Icom page at www.repeater-builder.com

What is the primary repeater?  This mailing list has over 4600 members, and
there are a LOT of junque boxes out there (for those unfamiliar with the term,
"junque" is high class junk).  Someone is bound to have the part you need.

If it's a UHF Micor station (which are famous for eating triplers) 
then I suggest
that you read this:


That article references the UHF mobile low level amplifier.
Mods to it are covered here:


I think that if you repair the Micor that you will find that when properly
set up it will easily outperform the Icom.

[Repeater-Builder] Icom IC-RP4520 Question...

[Josh]

Hello Repeater Builders!

I am seeking info on making an Icom IC-RP4520 (450-470
25 watt version) work on 442.825.

Background story: I am a member of the Shoreline ACS (near Seattle, WA) and our 
primary repeater is very old and is failing. It needs parts (tripler I am told) 
that we have been unable to find.

We were recently given an Icom 4520, and are hoping to use it as a replacement. 
 

Our repeater site is at a place called CRISTA here in Shoreline - our antenna 
is 183' up on their tower.  It has great coverage (when it works!).  

Any information would be greatly appreciated.  Thanks!
