A friend of mine did a test with a DR-1200 in the hey-day of packet and
checked the radio on a storage o-scope and discovered that the radio was
up at full power long before it was on frequency. :-/
That problem is not unique to Alinco.
We used Kenwood 531's for 1200 MHz packet links, and
Anyone help me I have a 1.2 GHz repeater, but no service monitor or
signal generator for these frequencies.
My service monitor, a Singer-Gertsch only goes up to 499.995 Mhz. I have
tried using the third harmonic in the 420-427 range but either the
service monitor is well filtered, or the
A real handy box that I've not seen and I wish someone would sell is
something that you could feed discriminator audio to and display
the currently heard DTMF string, DPL or tone PL.
An enhancement to the DPL / tone PL display function would be a
storage feature so I could park it and a
Anyone have any good recommendations for 23cm repeaters besides D-Star?
I've read about the Icom RP-1200 and using two TM-541s. Are there other
options that are as good or better?
The RBTIP pages have a lot of info on this topic.

There's only a limited set of European hams who have access to 4 meters.
Looking for a ComSpec Encoder/Decoder 32 tone.
The TS-32 has been out of production for many years now.
It's successor, TS-64, is available from many sources
(even companies like HRO carry them).
It is smaller, less current, and has more functionality.

Hi All, has anyone done this? That is, used a Yaesu FT-817 5w rig as a
remote base radio on your repeater? Any reason why/why not? Just
curious, thanks.
My FT817 shows signs of overload when it's connected to my external
(omni-) antenna, I'm about two miles away from the repeater site,
Nothing like discovering that your main corporate server hard
drive is a time bomb waiting to detonate. Or the drive in your TV station
production / automation system, your desktop PC, or even in that
external USB or firewire box that has all your family photos
and the 100gb of MP3s...
We have some on our repeater frequency, that just like to kerchunk
the repeater to hear it come back or ID. Is there any way we can
eliminate this annoying situation? I suspect that we may have
an unlicensed individual with a 2meter radio.
This actually isn't technology, it's psychology.
In the UK, Belgium and the Netherlands, CTCSS tones are assigned per
geographical area. For example, in the South of the Netherlands,
(where my machines are located), CTCSS tone is standardized to 71.9 Hz.
My question: What mechanism do repeaters in Germany use?
Is there a geographical
Anyone have a brand they recomend for a no noise, reliable fan.
I didnt know whether to go with brushless,ball bearing,AC, or DC etc.
Also should the power leads be sheilded and have a separate supply if DC..
Any filters recomended also..

We have been experimenting with building CTCSS Units using the
567 Tone Chip and good components, i.e. Caps, multi turn pots etc.
The stability is not good in my opinion.

For encoding, there's a million PIC-based solutions on the net.
I designed my own, using a different PIC (12HV615) to reduce
extra components to minimal: it has a built-in voltage stabilizer
(no 78L05 needed, just a resisitor), and using bitstream D/A
so no external D/A network neccessary.

I would use it on 1296 fm repeater and atv repeater 1240/1290.

Also saw a posting on e-ham that indicated only -30 dBc on harmonic
spurious for the UHF side (I assume that's 2nd harmonic).
I have an early KG-UVD1P (short DTMF burst) and an KG-UVD2D
and can confirm this is not the case on neither radio,
I measured -60dBc which makes them legal here.
73,
Since you have both, can you shed some light on the differences between the
KG-UVD1P KG-UVD2D?
I have been on contact with Ed Griffin from wouxun.us. He actually
does respond to email questions. When I asked him something similar,
he explained:
First there was the KG-UVD1, in which 1750 Hz
