Gee, Cecil, I was hoping to elicit something besides another rap on
CW!  Actually, it is those damn modems which are emulating we old CW
operators.  Why, back when I was a kid (:-), they didn't even _have_
modems!  Seems machines are always taking over our creative efforts.
They are fast, accurate, and stupid, and they don't know how to have a

I can get a crystal controlled radio with 30 watts output for 6 meer.
meter that is.

What is 6 meter like, is tehre a lot of dx or just local?
How far on an average day will 30 watts carry?
I heard 500 to 1000 miles is not out of the question with 6 meter.

True, although using it as a repeater extender can also be very helpful at
times (our club once had to set one up in order for operators sending traffic
for firemen and policemen at a major fire downtown between tall buildings to be
able to hit the repeater).

This is almost the scenario I had in mind.  The field operators and the base
would all transmit on one band and all receive on the other.

True, but it would still be nice for the operators not to have to worry about
remembering to ID the repeater, especially in an emergency setting when you
want to keep verbiage to a mininum.

A group of ham friends of mine, used to get together at a
restaurant late wednesday nights, and check into a net on
a (fairly) distant 2m repeater (about 50 miles).
Inside the restaurant, with HTs and big 5/8s, we could barely
hear the 350 watts of the repeater, let alone get into it...
Now, we discovered that a 5 watt HT with a big mobile antenna
in the parking lot, could get into the repeater...
So, we set up the HT into crossband... And we could get into
the repeater... Then we decided, now, if only we could hear
it better... so, we setup a second HT crossbanding the
repeater back to us (low power... even then, that little
Icom W2A would get toasty hot)...
Kinda nice, one of the guys had a 440 repeater pair for the area
that wasn't at use... so we just used that.
Eventually, we got some mobiles... and that made it alot
easier...  for ID'ing, we playing around with using a KPC3
with it's CW id... although, we also built some strange looking
circuits to do it also...

Enough of my rambling...  :)

This is interesting.  When I got my Yaesu FT-530, I made some crude
measurements of the power consumption and found that it never draws
more than 1.1 amps on 2m (slightly less on 440) .  If you apply 6
volts, it draws the least. Then it draws gradually more current as you
turn up the supply voltage, until it gets to about 10.5 volts.  It
draws 1.1A at 10.5V, and stays that way up to 16V (the max rated
voltage).  I didn't go higher, since it's my pride and joy. :-)

The receive portion is even more constant.  When sitting idle on both
bands with no power saving enabled, it draws around 100 mA.  It does
this at *any* voltage level (6-16).  It seems to be a constant-current
load for idle standby.  Of course, incoming audio, loud volume
settings, LED backlighting, and other stuff turns up the current draw.

I realize your resistor model was only an approximation, but I was
surprised to see that it controls its current so consistently over the
voltage range.  I could have measured it wrong, but that's what it
looked like.

Happy Hacking!

K3JL is on 147.075 MC.

You will likely be able to hit the O.City repeater with
a mobile radio on 147.015, using 5A PL. You can also decode 5A
on your end if you tire of hearing weak distant repeaters.

Mark has a UHF repeater in O.City on 443.45 MC, also
using 5A PL.

Now, N3OLY has a brand spanking new repeater coordinated
on 147.33 MC. I don't know if it is on the air yet.

How about a personal desire to transmit on the *entire* 420-450 MHz amateur
band? The 733 won't transmit all the way down, and there are legitimate
reasons to transmit there on FM, like testing of auxiliary links operating
between 420 and 430.

  I'm interested in this as well, where could I get such a repeater ? Cost ?

Hi Davin,

I'm sure many answers will accompany this one.  This answer along with all the
others should give you a clear idea what this method is.

The Farnsworth method of learning code involves spacing and character speed.
If you sent a 5WPM character {the letter "A"} [diiiit daaaaah] at a 5WPM
spacing [approximately two seconds between characters] and then sent that same
character again you would have...well....5WPM at a 5WPM spacing.  Sounds like,
diiiiit daaaaah --one-thousand-one one-thousand-two-- diiiiit daaaaah.  But,
let's say you sent an 18WPM character [Dit dah instead of diiiit daaaaaah] at
a 5WPM spacing:  dit dah --one-thousand-one one-thousand-two-- dit dah; the
character, itself, sounds faster but you still have that approximate two
second spacing between each character--and now the spacing seems longer.  The
faster the character speed the longer the spacing seems.  Kinda like it gives
you more time to figure out what the sent character was.

The actual goal is to not have to think about it as you decode each character.
Kinda like learning another language.  That only comes with practice and
eventually you will be hearing whole words and not just characters.  That's
down the road apiece for a beginner though.

Good luck if you decide to go for it.  It's not really as bad as *some* are
making it out to be.  And please don't judge ham radio by what you may read
on your monitor's screen.  You have to try it out for yourself and make your
own decision on that.  Don't let a few naysayers make that decision for you.
