One always should coordinate their repeater. Give much protection and keeps
others from being assigned your freq.

Hi all,
Couple days ago I set in a new DS repeater in my ID-800. However, later
noticed when this repeater came up there was no audio from the rig spkr.
I later found that I had turned on the CTCSS "decode" and it got programmed
along with the other DS info. Since DS does not use CTCSS it wou
My experience with buying D-Star rigs is with the IC91AD HT and ID-800 mobile.
I first bought the IC91 dual band HT for it was the least expensive way to go,
$400. I like the HT and used it for over 8 months and learned a lot about
D-Star. I could get into repeater on D-Star with 5 W solid tha

Did not think about the copywrite, sorry. I see stuff for 20+ old rigs and

Hi all,
One point on verbal IDing. When in a mobile I do not wish to be looking down
at my rig to read the IDs. This is danagerous. The automatic ID is great

I do it out of FM analog habit, but also as curtisy(spl?)
Hi all,
I find when setting up a rig having flow charts or some sort of quick reference

One posting stated the rigs in the repeater were modified ID-1 and ID800s.
Does this appear to be what is being used???
These rigs spec lower than typical good quality repeater rigs in spurious

The ID-1 and ID800 are definitly not repeater gear. The ID-1 tx has supurious
emmisions down only -50 db and ID800 only -60db. A good repeater tx would be

to make it perform better.

The loss isn't the problem. It's that Icom is using a single shield

This loss is about .11 db/ft, little more than RG58. If one used RG223 (double
shielded RG58) the loss would be about the same.
Going to RG214 loss would be .05 db/ft, an improvement.
All this is at 400 MHz.
At 400 MHz the .11db loss would be .63 watts from 25 watts. I don't think much

This was the reason the ARRL in 2007 attempted to get FCC approval for wide

Again the problem is the ICOM controller does not interface as most controllers

Maybe already ask, but have you monitored the RF power out to make sure it

If it does not then you are dealing with a weak signal at first.

ICOM locked their products to work together.

It talks to its repeaters with a CAT5 cable in a digital control

I aggree FD is a contest, but with the setup required to do a real FD, which so
many do, one does get the training in setting up an emergency station. One
learns about not only the radio set up, but feeding the animals, bath rooms
that are not always what one wants, bugs, generators and n

I do not believe FD has been diverted from “developing skills to meet the
challenges of emergency preparedness as well as to acquaint the general public
with the capabilities of Amateur Radio". I feel it still gives good practice
of setting up an emergency station, testing that station and
