Crescend Technologies P25-2AC1-C1-002 amplifier info?
Does anyone know anything about the
Crescend Technologies P25-2AC1-C1-002 amplifier?
I found one that is for sale and its label says it operates 42 to 50Mhz and 2.5 watts input for 250 watts out.
But I'm trying to figure out if it will for sure work okay on 6 meters, or if it can easily be modified to work there. I need it to operate on 53.19Mhz.
Has anyone successfully used one of these amps on 6 meters?
I have looked on the internet and have found no information on this amp. Even contacted Crescend directly and they told me they no longer have any documentation on it.
Thanks,
Dan

TKR-850 not being used. F.S.
Hello to all. I have a real nice Kenwood TKR-850 repeater that I have no location for. It is currently on 444.700. I will program it for you and ship it for 575.00. I also have several zetron 38A cntrollers (all have new memory and battery backup) with access code if you need a nice controller. Email me at jrbluz2@... or call 813-473-0831. Visit wb9zpy.com and thank you. Wayne

Re: CDM1250 rx audio from mic jack
? Yea I realize the jacks are different, they added a pin on each side of the regular 8. ?Everything is suppose to be the same as the maxtrax/radius series other then the extra ?pins for other use. As for getting the audio from the accessory connector, yes I can do ?that, but you can't set it for muted or PL in the RSS, only filtered or flat audio. That is fine ?for digital modes, but for echolink the software picks up the unsquelched?audio and ?passes it online so as people connected can't key up, plus no one wants to listen to ?static the whole time.?

Re: DMR & GMRS Repeater use of same antenna?
I've put ham and commercial repeaters on the same antenna before but it's not easy. It takes an extra 6 cavity duplexer that is notch only.. and very careful tuning. I once had two Motorola Quantars,? one on 444.5 and the other on 451.5 using one DB420. The extra duplexer inserted at the antenna feed and each side notched the opposite frequencies, both TX and RX. In fact I have a 2m repeater and a 150 MHz system sharing the same antenna right now using a DB4048 notch VHF duplexer to make them work without interference. Having a UHF ham and a GMRS repeater sharing the same antenna should be easy because the frequency split is a lot greater.? The frequencies involved need to be explored to make sure there's no inter mod mix when both transmitters are on the air and the transmitters need to be extremely clean on their output. Some people will say you need to have circulators in line but I've never had to do that and yes I've checked everything on a spectrum analyzer and everything was clean.
Chris WB5ITT?
I had a question posed to me so thought I would pose it here. The local club has a 7cm DMR repeater antenna is at 500 ft.. They are interested in adding a GMRS repeater use cavities to combine the two to use the same antenna. Has anyone seen that style of arrangement? I know major radio markets you see FMs use combiners, but this arrangement ?is not involving only transmit. Any thoughts appreciated.

Motorola GR1225 Hanging Open after random transmissions
An organization I work with has an old Motorola GR1225 (business freq) with an odd issue that we're trying to diagnose.? None of us are radio technicians...just audio/visual & IT guys (a couple of us with basic ham radio background).
?
After some transmissions (seemingly at random...maybe 2-3 times per hour), the repeater hangs open and transmits loud static for around 30-60 seconds.? In the last 10 (or so) seconds, the static begins getting quieter and cuts in and out until the repeater finally drops.
?
We were able to get our hands on the software and will be attempting to connect to the repeater for troubleshooting tomorrow.... in the meantime, does anyone recognize this behavior?? What should we be looking at to fix this?
?
Thank you!

He is not rebroadcasting the DTMF sequence, he is using the DTMF to trigger a macro to run a preprogrammed message stating that there is a severe weather alert.

Get this thru your head Tom...Any message transmitted by an amateur station, NOT SPECIFICALLY ALLOWED in Part 97 , is third party traffic and must be under a control operators control.
Sorry but it doesn't wash...you disagree? Go talk with Riley instead of ranting here because you are wasting time. The RULES are the rules..don't like them? Petition for a change but in the meantime FOLLOW THEM
Hence my question of the OP - If this is the local volunteer fire
department siren alerting its members to respond to a fire, the
answer is a hard no as this is anther radio service.
No, it is not. It is a message from the repeater that the siren has been activated. The message transmitted could be anything. It is no different than an operator keying his microphone and making the announcement. It is emergency traffic.
If this siren is activated via an NWS SAME alert to warn the
population at large, IMO would make more sense to feed the alert
into the repeater audio chain, with the ability to silence it with
DTMF or even a triple-click of the microphone.
There are those here who, wrongfully, say that isn¡¯t legal. It is 100% legal.? 97:115 does not apply since it is not third party communications. Emergency communications from any source can be retransmitted.?
|
That is improper control of an amateur transmitter..it can only be keyed by certain. equipment as allowed per Part 97. The control function activating the sirens is NOT permitted. I consulted Riley on this..
His answer:(and this is a direct quite)
"There's no use to argue with hypotheticals. Just let me know if he does it"
You disagree ?? Fine...face a NOV OR NAL.. I'm sleeping soundly knowing my repeaters are legal
Chris WB5ITT?
would it be possible to have a club radio located at the activation site for the tied to the siren controller, that would send the alert message to the repeater? then? only be activated?if the?control location activated the sirens.

Re: Getting tower sites for amateur repeaters.
"If you have a relationship with your local EMA" It never hurts to also have support letters - emergency manager, sheriff, fire chief. One time when I was trying to get a site I had a meeting with the fire chief (I don't think the meeting was even related). I mentioned what I was trying to do. While I was sitting there he picked up the phone and called the site manager and told him what I wanted to do. I heard the chief say that it would be a really good thing. The phone call wasn't more than about 2 minutes. When he got off the phone he told me the site manager also thought it would be a good thing.

You might have better luck with a local radio station with a FM tower. Talk to some of the other hams in the area, and see if there is a broadcast
engineer, or possibly a 2-way tech, that are also hams. They may be able to help open some doors. If you have a relationship with your local EMA, they may be able to arrange access to a county owned tower site.
In terms of access, again, I have seen everything from having a set of keys issued, to having to coordinate site visits more or less on the owner's
schedule.
Some may require a liability policy, and some sort of payment to offset the utilities.
Good luck! It is a worthy goal!

I've been debating on trying to aquire a site to put a repeater vs
here on my vertically challenged tower.
In the past I've found contact information & asked tower owners for
space. But this was probably 18yrs or more ago. One spot almost
worked out, but in the end engineers said the tower was already too loaded. So
that was a no go. Then at one other site I was actually offered space, but
I decided not too. Just because of location wasn't desirable to me.
Then I've also heard horror stories of tower owners changing hands
& Hams getting locked out & stuff turned off. ?
Now here recently I decided to kick the idea around about acquiring a
site again. In particular one of the sites I was almost in the
door on years back but engineers said it was too loaded. I've noticed the
tower has had most everything removed now. So I wonder if that might be a
possibility.
What I am curious about is what all is to be expected. So I
figured I'd ask here..since there might be a high probability of Hams with
repeaters on towers owned by others or government organizations.
Do you have to carry insurance with having space on them? Was is
difficult to get the equipment on the tower with red tape? Do you
have free access to go there whenever needed with keys? Do you pay anything
for the space? Do you pay anything for electricity? What do you feel
helped you aquire the space?
Little background about myself. I started off rock climbing in my
youth. I was already into radio. Later that led to working for a tower
company doing installation & tear downs of towers/equipment. This also helped
fellow Hams around me. I'd donate used long runs of heliax to
local clubs. Plus help put up repeaters & equipment on commercial towers for other
repeater owners. Im older now & I don't do tower stuff for others
anymore. Having kids & wanting to be around for them changed a few things
for me. Im still willing to do tower stuff for my own projects though, just
because of necessity.
I have land here. I've always wanted to just put up 120ft or more of
tower of my own. Life always seems to say nope. You can't afford
that now. Its a shame though. I actually live on a good size hill with nice
HAAT. Radio communications do really well here. Its just having a
repeater with antenna at tree levels still produces shadow areas plus foliage
antennuations when leaves & greenery come back in season. Ideally
having one here would be less worry I feel.

Re: Getting tower sites for amateur repeaters.
There are so many variables in this situation. I would immediately write off trying to work with any commercial?tower firms (Crown, American, Vertical Bridge, etc.) ONLY approved contractors and installation?methods, and almost a 100% chance you will need a structural analysis run.
You might have better luck with a?local radio station with a FM tower. Talk to some of the other?hams in the area, and see if there is a broadcast engineer, or possibly a 2-way tech, that are also hams. They may be able to help open some doors. If you have a relationship?with your?local EMA, they may be able?to arrange access to a county owned tower site.
In terms of access, again, I have seen everything from having a set of keys issued, to having to coordinate site visits more or less on the owner's schedule.
Some may require a liability?policy, and some sort of payment to offset the utilities.
Good luck! It is a worthy goal!

People skills really help.
Sometimes the city will allow the install if a approved contractor does it.
I've been debating on trying to aquire a site to put a repeater vs here on my vertically challenged tower.?
?
In the past I've found contact information & asked tower owners for space. But this was probably 18yrs or more ago. One spot almost worked out, but in the end engineers said the tower was already too loaded. So that was a no go. Then at one other site I was actually offered space, but I decided not too. Just because of location wasn't desirable to me.?
?
Then I've also heard horror stories of tower owners changing hands & Hams getting locked out & stuff turned off. ?
?
?Now here recently I decided to kick the idea around about acquiring a site again. In particular one of the sites I was almost in the door on years back but engineers said it was too loaded. I've noticed the tower has had most everything removed now. So I wonder if that might be a possibility.?
?
?What I am curious about is what all is to be expected. So I figured I'd ask here..since there might be a high probability of Hams with repeaters on towers owned by others or government organizations.?
?
?Do you have to carry insurance with having space on them? Was is difficult to get the equipment on the tower with red tape? Do you have free access to go there whenever needed with keys? Do you pay anything for the space? Do you pay anything for electricity? What do you feel helped you aquire the space?
?
?Little background about myself. I started off rock climbing in my youth. I was already into radio. Later that led to working for a tower company doing installation & tear downs of towers/equipment. This also helped fellow Hams around me. I'd donate used long runs of heliax to local clubs. Plus help put up repeaters & equipment on commercial towers for other repeater owners. Im older now & I don't do tower stuff for others anymore. Having kids & wanting to be around for them changed a few things for me. Im still willing to do tower stuff for my own projects though, just because of necessity.?
?
?I have land here. I've always wanted to just put up 120ft or more of tower of my own. Life always seems to say nope. You can't afford that now. Its a shame though. I actually live on a good size hill with nice HAAT. Radio communications do really well here. Its just having a repeater with antenna at tree levels still produces shadow areas plus foliage antennuations when leaves & greenery come back in season. Ideally having one here would be less worry I feel.?
