Something to keep in mind, is that the GP68 [and their chinese clones] are not
legal to use on anything other than ham in the US.
And, because it's also illegal to import them, they may be seized by Customs,
with no recourse.

Does anyone have technical info (i.e. tech drawings) or inside pics of these
duplexers? I wonder how they do the shortening as there can't be a 1/4 wave
resonator for 2m inside this 19 box...

Here's a question I've not been sure about: If a radio isn't Part 15
registered, is it even legal for ham use? If we build our own or
heavily modify, that's one thing, but I think if it's a commercial
product, it still has to meet FCC Part 15 doesn't it?

I have several MSF's, and am familiar with the radio.
I am not familiar with the Second receiver option, and have acquired
one on UHF.
How is this programmed, and can I put a SSCB on it?
Second, does anyone have experience setting up a SAM?
I have been tinkering, but it is so functional, I

I have two commercial UHF MTR2000 repeaters to each of which I have added a
Telewave TWPC-4508-2 bandpass cavity filter comprising two 8 cavities.
Both also have Angle Linear preamps followed by 6 dB attenuators to make up
for the 1 dB or so loss in the filter and improve the sensitivity of

Part 15 covers unlicensed operation. As a ham, you're licensed under the terms
of Part 97, which has specific rules for emissions types and purity. (97.305
and 97.307 in particular.)
If you buy a commercial product not already certified to comply, and were ever
accused of, say,

question.
Is is ALL VHF and UHF users? I was under the impression it was only the upper
UHF trunked systems and the like. But maybe I was confused.
Will many users have to dump their older radios and have to upgrade?
Looking for one or more RI-210 (VXR-5000 internal mount) to purchase or
trade for other VXR-5000-relevant hardware. (I even have an RI-310 I
could part with)
I'd be willing to take it with a 430-450 band or 2m-band VXR-5000, but
I'd prefer just the controller(s).

Albert,
This depends on the service. Public Safety and Business Radio services are
affected. Amateur Radio and GMRS are not - at this time. (IIRC)
I would certainly expect to see a glut of non-narrowband compatible
equipment enter the surplus market soon...

All true. However, I daresay that most of the non-convertible equipment has
already been taken out of service, long ago. At least in my area, most
users of high-tier equipment like Spectra, TK-990, and CDM radios are
replacing them because they are getting long in the tooth- and these radios
are
In Southern California under SCRRBA, we're already semi-narrowbanding
in the 70cm / 440mHz band to 20kHz per channel/frequency.
IIRC, FRS and by extension GMRS is already 12.5kHz.

I remember seeing a vertical dipole from one on the amateur antenna
manufacturers that was designed to bolt onto your mast or tower leg. I think
it might have come in a kit of 2 or 4.
I thought it was Cushcraft, but I couldn't find it. Does anyone have any
idea what antenna I thought I saw?
Cushcraft used to have that antenna. Since discontinued.

Cushcraft made a 4-pole array for 2-meters and for 440. Neither were
particularly good antennas. They were gamma-fed dipoles with a connector

Thanks for the info on Cushcraft, although I thought I'd run across the

I recently installed a Telewave ANT-150-D single dipole on a side mast for a

As have many other parts of the country - to 12.5 kHz on 440.
But, when you say narrowbanding, are you talking the actual users
switching from NBFM (16.0 kHz BW) to SNFM (11.0 kHz BW) or are you just
talking about the bandplan going from 25.0 kHz channels to 20.0 kHz
channels and everyone is
No, not all VHF/UHF, only the segments 136-512 MHz, and in those
segments only the FCC Part 90 users (Public Safety, Business,
Industrial, Etc.)

I'm sure someone on *this* list will be able to correct me if I'm wrong,
but I think you can mount virtually any of the dipole type antennas on
the tower leg as long as you're not looking for a 360 pattern. An offset
or figure-8 pattern, though, no problem. In fact, I've done this for
27 matches
