Re: [Repeater-Builder] Re: Repeater Kerchunk

[Gordon 'Yeti']

I agree with this - example being that there's a repeater that's fairly 
distant to me (easily managable from the house, but quite difficult from 
a car until I'm about 10 miles closer to it than I am at home). There's 
also 2 repeaters that are really distant and can vary depending on 
conditions.

All 3 of these repeaters operate as mentioned here  - If I key up and 
let go, there's a tiny bit of carrier as I unkey. If the carrier's too 
badly broken, I don't give my call, as it wouldn't make it in anyway and 
would just be plain annoying.

One of these repeaters needs a fairly long over before it actually opens 
fully and IDs itself. New users (including myself at one point) find 
this annoying, thinking that it's not working. I still forget 
occasionally to length my call by giving it in phonetics, and have to 
re-do it to make it long enough to open the repeater.

The local UHF repeater opens fully at any 1750Hz tone or CTCSS on the 
input, which means someone kerchunking it, or not making it in fully, 
results in 10-15 seconds silent carrier and the full ID every time (It's 
nearly 2KHz off frequency too, but that's just it's age!).

By comparison, the last repeater round here to not have CTCSS is a 
complete pig to open - deliberate or otherwise - and this results in 
virtually zero use.

I can't remember the last time I did actually speak to someone on the CB

Re: [Repeater-Builder] Somewhat OT - How to make HDTV *really* work

[Gordon 'Yeti']

Each state is just like it's own country anyway - it's own laws, taxes, etc.

Don't see why organising some radio transmitters seems like such a big 
deal - apart from that the US never made the jump to UHF, and buy the 
sounds of it, hasn't given itself proper preparation for Digital TV either.

Don't see why someone who knows about radios should find it so difficult 
to understand that the channel number displayed isn't always the channel 
matching the frequency the transmission is actually on.

Re: [Repeater-Builder] Somewhat OT - How to make HDTV *really* work

[Gordon 'Yeti']

This is to be expected from a country that managed to vote George W bush 
into power twice really.

You'd have thought you'd have discovered UHF TV a long time ago, like 
back in the 70s, like we did in the UK.

We have pretty much complete coverage (even in hilly areas) with UHF 
transmitters (and lots of repeaters).

Anyway, From the quick skim I've had here, Here's what I've read:

The TV channel named "Channel 7" is/was on VHF channel 7.
It's also now on UHF channel (30?)
So it's not long ON channel 7, altough it's CALLED "Channel 7".

Simple!

Class B was the old day equivalent of FRS, Class C is the Class D 
'alpha' channels.

With regard to Die Hard 2 - No wonder the military didn't have much luck 
decoding the scrambled signals - the handies are 440Mhz FM, and the base 
rig they have is tuned to the MGM segment of 2 metres!

Further question - are you sure it was the 41AT? And why were they illegal?

Re: [Repeater-Builder] OT: Radios and Coms in TV and Movies

[Gordon 'Yeti']

You think?

In Die Hard, the terrorists brough 'CB radios' - which were obviously 
UHF (Does the US still have a UHF CB frequency?) - Die Hard 2 - Kenwood 
2m rigs, with speech inversion. The handy on the Janitors desk clearly 
shows "144MHz" on it. Die hard 3 - Cobra 21 CB in the taxi, Cobra Marine 
band radio on the boat - with the lack of radios on the "police and FBI 
frequencies" clearly showing the writers are into radio. All the 'Police 
and FBI' radios in Die Hard 4.0 were 2m rigs, as said. Oh, and don't 
forget the geek in the basement with his 'CB' on 66.6MHz

The radio shown in the series opener for CSI:NY fitted to the police car 
was an Alinco on 220MHz.
