- This would be legal, if you could get it to repeat both ways. The
- common application of xband repeat is this. You have a dual band
- mobile and a 440 HT. You want to go fishing. Park car, and set up
- mobile to do x-band repeat as follows:
-
- In: 446.0 (for example) Out: 2m repeater's input frequency
- In: 2m repeater's output frequency Out: 446.0
-
- OK, so now you have a 440 extender you can take down to the canyon where
- the fish are...
-
- If you call out to your 2m repeater saying this is N1ABC, N1ABC repeater,
- that covers the first side of the link. But unless you have
- people cooperate on the other side, the 2m->440 side doesn't get
- ID'd, and that's the problem. You have to convince your
- buddies (and all those that aren't talking to you, but are on
- the 2m repeater) to ID your mobile for you, every 10 mins there
- is activity.
-
- Is this a real problem? Not, unless you are gonna split hairs about
- rules. But it IS illegal. The bigger problem with X-band are the
- bozos out there that don't know how to pick the right frequencies.
- The example given above is somewhat risky, since you are xbanding
- onto a repeater input.

-
- I see a lot of sensible commentary has been made, so I will touch on two
- things:
-
- When I was starting to play kid baseball, the kids in my neighborhood used
- to play a game called "burnout". Burnout was a simple game of catch, except
- that you would throw the ball as hard as you could when tossing the ball
- back and forth.
-
- When I was starting to play radio, I had a few kids in my ham neighborhood
- that I used to play CW burnout with. We would turn up the keyers as fast
- as we could manage to send, and wear each other out. Of course, when you
- are a kid you have a lot of time to do this kind of thing, but I found it
- paid off. If you have one or two friends who have the time and are at a
- similar skill level, this would be something to try.
-
- Secondly, I keep hearing this saying "good CW operators eventually learn
- to hear words rather than characters when going at high speeds." This
- has never been the case for me, or at least it has never felt this way
- in my brain. Perhaps this is why I never advanced beyond 65ish WPM. I
- only mention this because I don't think it's necessary to "hear words"
- to be a competent CW operator.

- Subject: Need some help with the design of an Operational Amplifier
- To: info-hams@ucsd.edu
-
- hello there,
-
- I have a question concerning design of a simple amplifier using
- operational amplifiers. I am simply designing a noninverting amplifier with a
- gain of 2, that is R1=R2 ( Closed Loop Gain=(1+R2/R1) ). No matter what I apply
- to the input of the amp the output always saturates to -11 Volts. Even if no
- input is applied the output still gives a -11V.
- The voltages that I am applying to the Vcc+ and Vcc- of the op amp are +12V and
- -12V respectively. I am using the LM 741 opamp for this application.
-
- Does anybody in this group happen to know what the problem might be?
-
-
- I would appreciate any relevant response.
-
- Please e-mail.
-
- Thanks in advance
-
- Chris
