[Repeater-Builder] Quantar Audio static

2010-01-20 Thread gregmrfs
Hi Everyone,

I have been tasked with programming and installing a UHF quantar by my local 
amateur radio club. I got it on the air tonight. The P25 side appears to work 
fin, however the analogue side has some annoying static at the end of the TX 
audio, just before the tails drops.

Basically it is just as the person dekeys, there is a split second of static 
prior to the tail dropping. The tail drops clean.

The unit is programmed with a 123Hz tone and 293 NAC.

Any help on removing the static would be appreciated.

Thanks

Greg

ummm-it's called a squelch burst or squelch tail or squech crash 
by most. It takes a short period of time for the squelch circuit to mute 
the receive audio, so a brief 'burst' is normally heard. To eliminate 
it, there are two main methods:
-All the users use commercial gear that has 'reverse-burst' or
'squelch-tail eliminator', which inverts the phase of the CTCSS tone for
abt 100-200 mS after PTT is released and before the transmitter unkeys. 
Anyone using a 'made-for-ham' rig will still have the 'tail'
-Install an outboard controller that has an audio delay circuit of some
sort in it. It delays the audio by abt the same 100-200 mS, but mutes
the repeat audio path instantly, closing the gate before the signal goes
away.

[Repeater-Builder] Repeater Linking

2010-01-20 Thread Jerry
OK, I know I've mentioned this before, but I think I'm on to something now...  
I wanted to have a stand alone repeater linker, kind of a crossband repeater, 
that would link uhf and vhf repeaters together without needing to make any 
changes to either repeater.  The problem I ran into is when the first repeater 
finishes transmitting, the linker will hear the second repeater (if the pl 
doesn't drop out) and will key up the first repeater again.  This cycle will 
continue until you turn off the linker.  I tried this with my crossband radio 
and it causes the same problem.


One solution is to have the repeater controller stop transmitting their pl 
right after the COR drops.  Not all repeaters do this, so you would have to be 
selective as to which repeaters you link.  

The solution I came up with today is to use a microcontroller with a built in 
a/d converter.  If after the first repeater stops transmitting, the 
microcontroller can sample the audio coming from the second repeater.  If I go 
through a high pass filter, I should (might) be able to determine if the audio 
is 'dead air', a courtesy tone, or someone talking.  If it's dead air or a 
tone, I won't key the linker.  I can then wait for the COR from the second 
repeater to drop, or listen for audio.



Do you think it will work?

Re: [Repeater-Builder] Repeater Linking

2010-01-20 Thread Paul Plack
Can you not get the cooperation of the operators of the repeaters you want to 
link? Without that, the technical issues will be the least of your problems. If 
they approve, the PL solution can actually work quite well.

The decision to be part of a linked system belongs to the licensee of each 
repeater. A remote which allows you to use your own repeater to access another 
is one thing, but linking two repeaters and their communities to each other 
through a third-party box without approval is a no-no in my book.

Re: Programming a GR300 repeater 

 In any event, the same software package will handle any 
 of the models I listed. The P/N is HVN8177, and is NLA 
 from Motorola. You will need the software, an old slow 
 computer running genuine MS-DOS, a RIB box, and cable. 

Actually... another option is available. If your computer 
will boot from an External USB thumb Drive... you can 
install DOS on the thumb drive, boot and program radios 
from it using various required software and the many slow 
down Moslo type programs. 

I'm doing that with a copy of MS-Dos 5.0 on a 2 Gig PNY 
Thumb drive and it works pretty well. The computer is a 
very fast CF-52 Tough Book.

Rich, it sounds like an antenna, feedline, or tower/site issue.  The easiest 
way to find out would be a dummy load connected in place of your antenna.  
Operate into the repeater locally with an ht and listen for any noise.  What 
you're describing is a fairly common problem with repeaters that share an 
antenna for tx/rx.  How was the antenna Tested?  A simple vswr test usually 
won't reveal this sort of problem.  Its usually caused by loose metal-metal 
contact in close proximity of the antenna.  However anything's possible :)  73

Since the typical BpBr duplexer uses an adjustable capacitor to tune the
notch, I would think that one or more of those capacitors would be the most
likely component to be damaged by a lightning-induced surge.  For example, a
Sinclair Q202G duplexer uses Johanson piston capacitors which have extremely
close tolerances to achieve values of 10-30 pF.  A digital capacitance meter
could be used to measure the value of the notch tuning capacitor in each
cavity, to find one that is out of family.

Yes, its certainly possible a piston capacitor could be damaged due to 
lightening, but I'd think this would more apply to a direct hit scenario.  
It'd also be very apparent during tuning and would likely have a profound 
impact on system performance.  There are also many cavites that don't utilize a 
piston capacitor for reject notch, i.e. many of the popular Wacom BpBr vhf 
duplexers: WP-641, 642, 643 etc.

 Everything indicated they were functioning normally. Till we put them back
 in service. I don't know if they were tested with a dummy load. The
 technicians made many trips to the site: the technicians worked for the
 company that we rent the site from. We replaced all of the connectors and
 only found one that had scorched indications on it, but that was all.
  I asked if any of you knew how to find out if a can was operational,
 because all the test equipment that was used indicated they were ok. We
 finally found a workable solution. We added a fifth can, tuned to the
 transmit freq. That stoped the crackling noise. 
  Now we're going to replace the can's, and go with a 6 can configuration.
 this is what was reconmended by the technician.

I thought I'd better update the list on what was found.  First off, the
entire repeater was taken in to the shop for exhaustive testing. The can's
were taken apart, inspected and cleaned. All that was visibly found was a
little carbon. The two service monitors showed they were working ok. But,
when placed back into service at the site, the transmit side leaked into the
receiver side. It presented a crackling noise, like saran wrap being
crushed. I don't know if the technicians tested the repeater at full power,
( 110 watts) during testing, but I think so.

We did solve part of the problem. A fifth can was put into line, on the
transmit side and by golly, it did the trick.  The repeater is sounding
better than before the strike.  

Interesting enough, there are two or three UHF repeaters also in the site,
and none were affected?

We're now looking for a 6 can set and controller.

I'll share with you when we finally find out where the problem is.

---Hi Gervais. You're thinking of the TKR 
series. As for power, you can always add an 
external amp if you need more power.


Here's a link to the brochure about them

Gervais, 

Are you buying the Kenwood from a Kenwood dealer, or a private party?  

Any good Kenwood 2-way dealer should be able to help you obtain proper 
manuals/documentation for it, unless it's an old enough model that 
documentation is out of print.  

A GREAT dealer will help you find the manuals, program the repeater, etc... 
even if you bought it from someone else, perhaps charging a reasonable price 
for their shop technician's time.  

A merely good dealer might not be as motivated to assist, but usually will.
