[Repeater-Builder] Ruggedised panel antennas

Hi Group, 
I'm just wondering if anybody has an alternative to Katherin-Scala for heavy 
duty radomed panel antennas in the 450-500 MHz band  at around 10dBi gain that 
will stand up to the abuse of an alpine site (>2Km ASL)

[Repeater-Builder] Re: MSF-5000 information needed

[wb6dgn]

The TPN1186 power supply provides a high current (approx. 36A.), 13.8 volt 
source and two lower current 13.8 volt sources, fused at 6.3 amps each.  There 
is also decoupling and filtering on a "distribution board" which also provides 
overvoltage and overcurrent protection.  Depending on your "12 volt" source, 
you may want to find a "parts donor" power supply and adapt that distribution 
board to suit your needs.  The lower power (150 watt and below) stations do not 
use any supply voltage above that 13.8 volts, however.  One thing that you will 
need, however is what Motorola calls the "Low Power Control Head".  This is a 
rather deceptive name for a rather simple device that senses forward and 
reflected power and sends that information to the power control circuitry in 
the RF tray.  This information is normally located on one of the RF amps. (I 
forgot which) but when the PA's are not used, the "control head" performs that 
function.  Schematics of the power supplies and the "control head" should be on 
Repeater Builder TIP pages or they can be found in most of the MSF service 
manuals.  Good luck,  Tom DGN

Re: [Repeater-Builder] Re: More on GMRS - Fwd: FCC NPRM proposes complete part 95 rewrite

[Mike Morris]

Sounds to me that you have  the perfect opportunity to
make a major point if you reply to that NPRM - chaos
will rule without active enforcement (just like on CB and FRS).

In the NPRM they want to drop all licensing - even license-by rule.
And we have seen just how well license-by-rule works on FRS.

One of the major points I am making is that there is no
visible enforcement effort on GMRS and there needs to be.

Except that as Corwin pointed out the other day, it hasn't been posted

that happens, and then there is 30 days after that.
However, putting comments together NOW and sending them in is good-but

[Repeater-Builder] Reminder - GMRS NPRM

[Mike Morris]

Just an FYI reminder on FCC Docket NPRM 10-119 that totally
restructures GMRS and wipes it out as we know it.

Replies are due the 7th.

That's TOMORROW.

If you have a personal dog in that fight it's time to get moving.

Major points:

GMRS channels become more FRS channels.

Power goes up to 2 watts on all channels.

Drop all licensing and age limits (can you say 27 Mhz CB-type mess ?)
Any experience you have with unsupervised small children playing
with FRS radios and how that would destroy what GMRS now is would
be helpful.
No licensing also would mean the end of the limits on commercial
businesses usurping or taking over GMRS for business band use.

One of the major points in the Docket is that there will be no more
repeaters - this is a major point to anyone that uses a GMRS repeater.
Everything will be simplex. - and it's a well known fact that UHF
ground-level simplex is useless at over about 30-40 miles due to the
RF horizon and earth curvature.  Back in the 60s the US Army
experimented with troposcatter at VHF and UHF, and discovered
that VHF would work, but UHF would not, even with 10kw at UHF.

No licensing would also result in the end of any meaningful way to
regulate or limit who uses a repeater.  If you operate a GMRS repeater,
or if you are part of a group that sponsors a GMRS repeater
this could destroy your ability to control who uses your system.  It's
vital to make the FCC aware of the absolute necessity for licensing
for shared use of repeaters.

Both call signs and any identification would be eliminated under
the proposed new rules.  But the FCC would still expect GMRS users
to "cooperate in the selection and use of channels, including limiting
communications to the minimum practicable time, to reduce
interference, and to make the most effective use of the facilities."
[Proposed rule 95.103(a).]
Yeah, right. You need to explain to the Commission that coordinating
with others in the absence of any identification is completely
unworkable and totally impractical.  (Note that in paragraphs
19 and 20, the FCC recognizes the importance of facilitating user
cooperation by proposing to continue specifically disallowing
voice scrambling.)

Drop all existing type acceptance - you will have to buy all new radios.

Docket 10-119 discusses somewhat that the development of cellular
telephone has lessened the need for GMRS.  You need to explain
to the FCC the types of communications that GMRS is used for ,
and can not carry out with cellular or any cellular-like system. (For
example communications between 3 or more units at a time or in
areas where cellular coverage is poor or non existent - like after a
disaster.  It's a well known fact to everybody but the Washington 
DC 
bureaucrats that cell phones DO NOT WORK in a disaster.)

Some radios are easier to interface to a repeater
controller than others.
Transmitters are not hard - audio and PTT. Receivers
are another case - you need to find a carrier sense
point and a tone decode sense point.  What radios
are you going to be using?

And don't forget duty cycle - the average mobile radio transmitter
is 10 to 20% (look at the spec sheet for the particular radio). In mobile
service the mobile transmitter is used rarely.  In a repeater it's used for
ALL user transmissions, one after the other.  In some cases it may be
on 80% of the time - and the average mobile will meltdown in that
situation...

Stan,

Ugh!

That will make it extremely difficult to figure out what is going on.  What

Typically it should have PL card and R1 Audio card (these are installed 
horizontally above the normal vertical cards), Squelch gate card and Station 
control card.  It might also have a time out card and Line card.  

Is the pacific research controller with the repeater?  

I'm not sure where to tell you to start.  Examine each card for any mods. 
Collect as much documentation as you can about what was done.  

Basically a controller requires a COR signal from the receiver, a PTT to the 
transmitter, Receiver audio going to the controller, TX audio from the 
controller to the transmitter, and a PLL indicate.  If the controller is still 
there you can work backwards from there.  There are several places where these 
signals are available.  Either on individual cards or from the backplane.  Look 
for additional jumpers on the backplane.  In original condition there are NO 
jumpers from any of the backplane pins.  

Get yourself some manuals.  I can try to help you as much as I can.  The 
receive signal flow is from the receiver to the R1 audio card.  This card has 
the local volume control and the squelch control.  It provides the audio amp 
and squelch circuitry for the receiver.  From the receiver the signal also goes 
to the PL and Squelch gate card.  The PL card decodes (and provides receiver 
filtering if so jumpered) PL and sends it to the Squelch gate card.  The 
squelch gate card processes the audio from the R1 card and sends it to the 
transmitter.  It also provides the transmitter keying signal.  The keying 
signal goes to the Station control card through the front panel card controls.  
From there it goes to the transmitter.  There is also circuitry for delaying 
the de-key of the transmitter to accomodate the reverse PL burst.

Stan,
 
Ugh!
 
That will make it extremely difficult to figure out what is going on.   
What cards are in the cage?
 
Typically it should have PL card and R1 Audio card (these are installed  
horizontally above the normal vertical cards), Squelch gate card  and Station 
control card.  It might also have a time out card and Line  card.  
 
Is the pacific research controller with the repeater?  
 
I'm not sure where to tell you to start.  Examine each card for any  mods. 
Collect as much documentation as you can about what was done.

I'd still suggest that he try them since he already has them. If they don't 
work out, so be it. They can easily be swept to confirm the results, too.

I was just quoting the sales flyer.  I agree that the bandpass curve has 
the typical "knee" shaped bandpass curve instead of the bell shaped 
curve for what I would call a bandpass duplexer.  The only real 
application that I can see for these duplexers would be a mobile 
installation that is operating in the full-duplex mode.  It's 
interesting that they picked 52 and 53MHz on the plot, maybe they were 
targeting the ham market?

[Repeater-Builder] MSR2000

[Stan]

Yesterday I finally plugged this MSR2000 in with a dummy load on it. It came on 
with an open squelch and went right into transmit mode. The squelch control on 
the squelch gate card did not close the squelch. I cannot find any way to close 
the squelch. If I pull the squelch gate card out it quiets the squelch.

I hope it is not a defective squelch gate card.

Warm likely - maybe even hot,  but certainly not fuzzy.   - - Sort of
