[Repeater-Builder] Re: Vertical squalo as 6m repeater antenna?

[cruizzer77]

This DDRR antenna is also new to me but space-wise it is even smaller than the 
squalo so definitely worth considering, especially because I wouldn't want to 
try the squalo if the majority says it won't perform as expected.

Would you use just one of them even though it's on the side of the tower or 2 
or 4 of them around?

Kevin,

I agree that its hard to bet Motorola but since the firmware is not even
released yet for the repeater how can you say the Voip stinks. Also you say
when you stick 10 pounds of crap in a 5 pound cabinet your going to have
trouble. Crap, if you were to see what is inside the repeater I think you
will change your perception. I will snap a few photos today and send them to
the list.

Hi Group,

Just curious if anyone has had a play with the new HYT (HYTERA) RD982 series
of repeater, and more importantly the Ethernet connectivity. 

 

Certainly the gear looks good on paper and in real life, but interested in
feedback on anybody that has had a chance of really giving it a workout.

Yes, the only thing both radios will not do is text between both models.
Motorola is not doing there text features to the DMR standard and Hytera is.

Re: [Repeater-Builder] DMR Repeaters

[Gareth Bennett]

Hi Mike, That's what I've heard as well. 

What I have briefly learnt about the  RD982 platform is that it has been 
carefully designed after learning from other vendors mistakes and LEARNING from 
them. The quality is such that one could re-badge the radio as a new generation 
Motorola and get away with it. I know for a fact that Motorola are very 
concerned about HYT.

 The RD982 platform has been loosely based on the Australian Spectra 
Engineering MX900 series of repeaters, which ironically is rebadged and sold to 
MOTOROLA as the MXD1500 series of base station. This infrastructure is well 
respected in the professional industry.

Re: [Repeater-Builder] Re: Vertical squalo as 6m repeater antenna?

[Joe]

I prefer the ground plane for my 6 meter repeater.  Look at these two links:
http://www.repeater-builder.com/db/pdfs/db-201.pdf
and
http://www.repeater-builder.com/db/pdfs/db-201.pdf

They are rather simple antennas, very durable and last a long time.  I 
have one at 30+ feet now for several years and never had a problem so 
far. It's at the top of the tower and the folded vertical element makes 
it a grounded element antenna, important for lightning damage 
avoidance.  I also believe it is a little quieter relative to wind 
noise.  A single antenna mounted out on the far edge of the platform 
should work.  If it is a monopole tower, you would probably want to 
mount the antenna so that the less favored direction is towards the mass 
of the tower.

Henry,

I have an RP-3010 that someone reprogrammed the callsign for me.  That 
was back in 1999, he may still be around and willing to program your 
EPROM possibly for a small fee.  Email me direct and I'll see if he is 
interested, if his email address is still good.

The original ICOM controller is very, very simplistic and does some 
annoying things. I would not waste my time reprogramming it.  There are 
some inexpensive controllers out there that would run circles around the 
stock ICOM controller.

RE: [Repeater-Builder] Re: MOVs for power supply primary

[Eric Lemmon]

A Gas Tube Arrestor is better suited to telephone lines and RF coaxial
cables than to 120 VAC AC power lines.  If used on AC power lines, when
fired, they will produce a "bolted short" and cause a great deal of current
to flow.  This is not a good thing!

Some computer accessory suppliers vigorously market surge arrestors as a
must-have accessory, and the American public is being brainwashed.  In fact,
most computer circuits do not benefit from surge arrestors, and some power
strips that include surge arrestors are banned by many large companies as
being prone to catch fire.  The gray plastic, half-moon-shaped power strip
made by APC is known to be a fire hazard, and my employer (Boeing) banned
them after the second fire incident.  In each incident, the MOV
spontaneously overheated and melted the plastic case, which then caught
fire.  Fortunately, the damage was limited to the wooden shelf it was
sitting on in one case, and some scorched carpet in the other.  As a result
of these two incidents, the CPSC recommended that any power strip be made of
metal rather than plastic, and further, that the plug strip containing a
surge suppression device always be placed upon a non-combustible surface.  A
word to the wise...

Anyone use those?

[Matthew Kaufman]

If you're ever in a facility served with a nice on-line UPS, a smart 
site manager will tell you that you can't have surge protecting power 
strips because the clamping behavior is really bad for the UPS inverter 
outputs and does more to damage other people's power (and the UPS) than 
it does to "save" your gear.

[Repeater-Builder] WTB transistor M9887

[rfburnz]

The M9887 is a tripler transistor in the UHF Mitreks and MSR2000, I need one 
and wonder if anyone has one (new or used) - I just don't want to buy a Mitrek 
becasue of the shipping, but the MSR exciter is small enough I  would purchase 
the entire module if someone has one, please let me know There is no known sub 
so please don't suggest anything else. This is a weird transistor as it has the 
Emitter in the pin that is normally a Collector pin in similar looking packages.
Thanks in advance!

Re: Icom Repeater Eprom Reprogramming 

It was probably me... but I didn't and don't charge for doing 
them/it. 

I can do it, but right now you have to be very patient with 
me as I'm up to my backside in alligators and I don't even 
have a swamp nearby. Meaning I'm working long hours on a 
major project that needs to get done on schedule. 

There is more than one Icom Repeater Controller Version with 
Eprom contents storage.  Whom ever reprograms your Eprom will 
probably need to know what the CPU is and the size of the last 
Eprom that worked.  I know for a fact that more than one size/
type of Eprom was used. 

What happened to Icom Customer Service?  Remember I'm a Kenwood 
Dealer... :-) but I'll still help you. 

So Email me later/direct if no one else offers to help any 
sooner than I can get back to you. 

cheers,

Keep in mind the DDRR Antenna is a reduced size vertical polarized 
antenna and the Squalo & Ho-Loop are normally considered full or
standard size loop type antennas that are horizontally polarized. 

And most mobiles working FM are vertical polarized signals.

It should preform exactly as we expect it would. But not as 
you might desire it would...

Squalo &/or Ho-Loop rotated out of the normal mounting plane 
and installed on a tower?   Zero or not 

Your intention of possibly mounting a rotated Squalo or Ho-Loop 
is a popcorn fart.  They are normally considered a standard size 
loop and by the time you get one installed you've practically 
reached the size of a standard 1/4 ground plane. So avoid the 
obvious waste of time... and money. 

DDRR Antenna mounted on a tower?  Only if there were no other 
decent options.Maybe, but I've never run into that situation.

That transistor alone is gonna cost about $40.00 If someone has a rig for 
cheap, way to go in my opinoin. If I had one I would send, unfortunately gonna 
pay "mot" $

[Repeater-Builder] OT: Wanted Parts for Hitachi V660 or V665 O-Scope

[d0ugjensen]

Hi, I am trying to fix an old scope, Hitachi V660.
I need the front toggle switch, front trim, and maybe some other parts.

If you know anyone scrapping one of these, or where I can get parts, please 
contact me.

[Repeater-Builder] Re: Repeater radio needed-rig advice.....

[burkleoj]

I would look for some of the newer radios like the SM50/SM120 series or even 
newer CDM series of radios from Motorola. The early pc programmed Motorola 
radios (Spectra, Maxtrac, Radius 100..etc)draw a LOT of standby current and are 
not the best option for a solar site. The radios need to be current friendly 
unless you have a lot of battery and solar panels with power to waste.

Re: [Repeater-Builder] OT: Wanted Parts for Hitachi V660 or V665 O-Scope

[kevin valentino]

just a possible catch if i am wrong,let me know, that is 60 mhz, dual trace, 
with delay time base. correct?
