Of course this presumes each radio can supply enough level. If not

easiest way to implement this).


The RAD expects 1 volt p-to-p max do don't overdrive it.

what are you using? are Arcom? or Scom?

If your using a arcom, take the jumper out of the delay board headers that
jump the audio for each port, bring the audio out line
(JP10-2,JP11-2,JP12-2) from each header into a mixer, run the output of the
mixer to the audio input pin on the delay board, then just split the output
of he delayboard however you want to, to the audio input pin on the delay
board header (JP10-3,JP11-3,JP12-3), then you can set each tx level via the
onboard pots.  

Not sure on the scom, have to look at a schematic.  


Thats the concept anyways.

In the 7330 each RX input has its own audio delay and each TX output has its 
own 3-input mixer with a driver amp and level pot. No mods needed.

RE: [Repeater-Builder] Re: spectra tranceiver with 9a dual heads

[David Murman]

Randy, once you load the codeplug hit the escape key. This brings you back
to the main menu. Go to F4 then F5. This gets you to the MODE config menu.
At the bottom of the screen F8 is the mode utility. At that point you can
add or delete modes. Use the F1 key to get any help.

 

Deleting trunking modes you will need the syskey.

 

Hope this helps.

Eric,
I don't think they are landfill material yet. I think you will find that
there is many of them still in service. 

I know in one of the sites here locally in Southern Oregon, my Micor ham
repeater is surrounded by 5 MSR2000 VHF repeaters still in commercial
service.

You have to remember that they were the replacement for the Micor line of
radio. Most agencies and businesses in a lot of areas that had Micor
repeaters did not replace them with the MSR2000 radios as Motorola had
hoped. 

When Motorola built the Micor it was over-designed, over-built, and super
reliable. Motorola sold them like hot cakes at a fireman's breakfast to just
about everybody that had a need for a repeater. When the MSR2000 came out
the Micor was still king of the mountain and most customers and tech's did
not see the need to replace a relatively new perfectly good working
repeater, simply because Motorola had a new offering.

In my experiences and observations there was a fewer number of the MSR
series of radios that were sold when compared to the Micor series.

I have seen quite a few of MSR VHF repeaters come out of service, but have
not seen any UHF MSR's at all around here. Overall in looking for some
myself, I have seen more UHF MSF5000 series repeaters surplus than UHF
MSR2000 repeaters.

Good luck with your project. Don't give up, there has to be some of these
radios out there somewhere. If you come across a gross of them somewhere I
am looking for a couple myself.

If you have the software to program the radio there are help files. Just
press f1 after opening up the program and reading the code plug. If you

weekend wrapping up. I've noticed a number MSR-2000 Units out 
in the flea market... I'll try to remember to get their contact 
information. A complete VHF MSR-2000 Repeater is/was priced 
at $50 today and still no takers yet. Even had the large internal 
VHF duplexer installed. UHF units are not as common but I 
haven't been paying that close attention. 

Bright sun today and an number of the Group Members here are 
looking pretty lobster red. The brauts/brats are good but the 
sodas are priced at $3 each, which I think is a bit much. 

Great to meet a number of Group Members here... some of you 
I wouldn't buy a car from but I think that also works in 
reverse... not that I'd want to part with a precious 137,000 
mile Yugo. 

Surplus radio gear here like crazy... GE Rangers going for 
$30 to $40, Maxtracs going for $40 (all bands), all kinds of 
hand held radios and a lot of vintage land mobile (two-way) 
radios are reappearing one more time. 

Solar Panels are bringing in prime dollar and fairly few relative 
to previous years. 

The hard hat with top mounted mini tower and yagi beam guy is 
here walking around. Just a few Hamsexy T-Shirts in the walking 
around crowd. 

Coffee wasn't strong enough... 

s. 

Give us some time to get home and we'll share the contact 
information for any UHF MSR equipment we might see and remember 
to write down.

Re: [Repeater-Builder] PIC stuff at Hamvention?

[MCH]

Oh, and I was just looking for a Hamvention source for chips or other 
related items. I've been playing with them, and wanted to find some good 
deals. I have a couple development boards, and I've been writing code in 
ASM.

[MCH]

Actually, Byonics is using the AT Mega (sp?). I specifically asked. At 
least, that's what the TT4 is using.

Re: [Repeater-Builder] Techniques for combining multiple audio sources

[Jeff Ackerman]

what are you using? are Arcom? or Scom?

If your using a arcom, take the jumper out of the delay board headers that
jump the audio for each port, bring the audio out line
(JP10-2,JP11-2,JP12-2) from each header into a mixer, run the output of the
mixer to the audio input pin on the delay board, then just split the output
of he delayboard however you want to, to the audio input pin on the delay
board header (JP10-3,JP11-3,JP12-3), then you can set each tx level via the
onboard pots.

Not sure on the scom, have to look at a schematic.


Thats the concept anyways.

[Repeater-Builder] Re: Coupling cavities, cable length, and notch/bandpass configuration

[spradio2000]

Sorry, my ascii pictures get messed up. The preview looked great.
Even when you write a reply, the ascii drawing looks fine tin the preview 
window.

[Repeater-Builder] Re: Coupling cavities, cable length, and notch/bandpass configuration

[spradio2000]

Hi Kris,

Sorry, I use 3/4 wave cables, not all cut to perfection.
I measured lengths for the t-connection exactly.
Fro the center of the T to thye beginning of the loop 3/4 wave, or should it 
have been from center T to center T.

I have homebrew filter with six 10cm diam. cavities, and six commercial 
bandpasses, of which I use six as band rejects.
I might want to try using a Johanson trimmer in the loop to try and create a 
bpbr cavity. Have not experimented with that yet.

In pictures I see twoo br or bpbr cavities and one bp cavitie, of which the 
last (bp) is couples to the br with longer cable.
Looks like 1/2 wave, can this be correct?
