I recently opened up a Polyphaser unit we used on one of our remote sites.
it covered both 2m and 70cm. We were experiencing poor receive at the site.
Replaced the unit and receiver sensitivity is once again hot. Anyone want
pics of the insides respond direct and I'll ship you the photos.not
Hi folks,
We noticed reduced sensitivity at one of our remote receivers recently.
Went out to check things. All looked good. SWR to the receive antenna was
good. Check it with and w/o Polyphaser in line.
Replaced Polyphaser and tested again. same SWR but sensitivity much
improved. Is this

No argument on more going on with D-STAR you can see it happening now.loads

D-STAR may not be adopted by the majority of VHF/UHF users until the
end-user gear prices drop significantly. I think there will be too few users
to justify the efforts of a trustee or club to migrate to D-STAR/digital.
One D-STAR follower noted 12,000 units sold globally. That number of unit

Dave, I just wanted to update on developments on the amateur radio
Hi Folks,
Our club has been given permission to use one of the Public Safety antennas
for our 2m repeater. The antenna is a PD-220-3A 150.5-158.5MHz. Our repeater
freq. is 146.745. The antenna is fed with some nice looking Cell Flex
LCF-12-50 ju, hard-line. The PD-200 is one of those totally
Hi Chuck,
We couldn't do a proper test this weekend. The hard-line had its connector
cut-off and we didn't have a compatible connector for this type hard-line.
Ordering a connector today. I'm guessing about 3:1 but won't know for sure
till we get some RF into it.
Best,

Hi
Strap meaning solid copper, not copper or silver tinned braid. However, one
might argue that the copper tubing has an equal amount of surface area and
is more robust than the thin copper strap being sold.. if you fold 3 wide
copper strap into a piece of tubing you get a ¾ OD tube. So, does the
Softdrawn copper tubing comes in spools of 25-50-100ft.

Richard,
The FCC has always had that option to re-assign spectrum.you use the term
our frequency which implies you think we have some implied rights to
utilize the spectrum. We have no rights, just privileges.
The FCC can change those privileges any time they want, as they have just
done in

It's operating on a ham band at more than flea power-maybe as much as
several watts. How can it NOT interfere
Ah George,
Don't worry! The first time the device fails to deliver the goods to the
Public Safety guys, they'll stop using it. Good luck to them. They'll have
fun running up against the 1,000watt erp of many 70cm repeaters.

Here in Arlington County, VA OEM/RACES we have two Internet Remote Amateur
Radio (IRAR) Stations build around the Kenwood TS2K w/ 80-6M and 2m-70cm
antennas.
Our RACES volunteers check-in to the weekly exercise nets using the IRAR
stations when they are traveling for business or just for fun.
Well, the operator knows that EL broadcast immediately after the IP
connection is established. SO, in my view the operator should know better
than to place the radio on top of a net freq. I'm speaking of 'control'
operator, not the user at the remote end of the Internet connection.

EL is just another control link method - in his case land line.
That said, EL should be smart enough to not transmit on active
frequencies. That's a shortcoming of EL or the interfacing, not
necessarily the operator.
