- In general it's unnecessary, but things which are defined as "in
- general" usually have exceptions. Take for instance the case where Bob
- is monitoring a scanning receiver which is in another room. All of
- Bob's friends know that he is listening on the scanner and that it
- takes him a minute or two to come to the radio. In this case, the
- calling parties will mention which frequency they're on so that if Bob
- hears it, he'll know which frequency to tune when he gets back to the
- radio. This is no hypothetical case - Bob, K7PYD is a friend of mine.

-
- Ok. I will if you will. When running the Phoenix Arizona

- "QSL" than it is to understand "uh huh", "yup", "Yeah", "uhhhhh,
- OK", and so on. I don't ask people to use "QSL" but it does
- not bother me when they do. The message is received and I move

- So what? Everybody disagrees with everybody. What else is new?
- 40 or so years of being anally retentive doesn't mean much to me.

-
- People do it in person, why not over the radio? When I talk about
- computers, I'll mention a VESA card and 8 meg of RAM. Should I
- have said, "A Video Electronics Standards Association card and 8
- Megabytes of Random Access Memory"? Every hobby and activity

-
- There's a big difference here. For starters, there is no rule anywhere
- that states that any of the above mentioned practices are illegal.
- Granted, they may be unsavory, but they're legit. For example, you can
- note that a linebacker is ugly, but you can't flag him for it. It's
- just not in the rules. You just shrug your shoulders and go on about
- your business.
-
- Have a nice day. And remember, it's a Hobby!

- Subject: Jupiter / Comet collision & radio astronomy
- To: info-hams@ucsd.edu
-
- There has been quite a flurry of activity in the popular press about the
- forecast upcoming collision of a comet with the planet Jupiter in the July
- time frame. It is supposed to be quite an event, even though the collisions
- will occur on the far side of the planet.
-
- Some time ago, I remember an article by Cornell Drentea in Ham Radio
- magazine about "amateur" radio astronomy and the ability to sense radio
- emissions (and I believe they were from Jupiter) in the 14-16 MHz range.
-
- Has anyone seen any announcements or know of any attempt to monitor the
- radio wave emissions of Jupiter during this event? Certainly, most of the
- worlds optical telescopes will be trained on this, but is there any "grass
- roots" personal / amateur coordinated effort at monitoring this?
-
- Please reply to the net or directly to: johnk@ATK.COM

- Thanks 73

- You may not know it, but they already do! The Federal government employs
- physicians who need not pass the licensing exam of the state they are
- practicing in. I haven't noticed that the veterans are dropping like
- flies from inadequate care, though.
- Having worked as an 'unlicensed engineer' for RCA designing microwave
- circuits (back when they still did that!), I don't see the need for
- eliminating this exception. Perhaps you can cite some cases where
- having passed the PE exam would have saved lives and reduced damages.

- Subject: RFD:Radio repair rip-off??
- To: info-hams@ucsd.edu
-
- I'd like to get the groups opinion. Keep in mind while I know some
- radio theory, I'm no repair person. Question: I decided to try
- to get my original transceiver a Kenwood TS 520 back on the air.
- In trying to tune up, there was basically no power output. So I
- left it off a a local repair shop and told the owner I though it might
- well need new finals and alignment. He charged me a $45 "bench fee"
- which would not be refundable but would be credited toward the repairs,
- and bascially sat on the set for a couple of weeks. They send the
- work out to a technician. Anyway when I called back for the estimate
- they gave me a quote of $225 to $250. It was apparent that they never
- actually opened up the set, and that the quote was based on my
- impression that it might need new finals and alignment.
- So I was miffed that the so called "bench fee" estimate was not
- based on their actually looking at the set, and that the estimate
- appeared to approach 60% or more of the value of the transceiver
- judging from prices I've seen posted for used equipment.
- Perhaps I should have been more "aware" of the potential for losing
- my money. My questions are: (1) shouldn't I have expected them to
- have at least opened the set up for the $45; (2) could the repairs
- really be expected to get into that range, assuming the worst.
-
- Thanks for thoughts,

- Actually, with the right circuit, you can reliably pull a fundamental
- crystal 1000 PPM (i.e. +/-500 PPM). If necessary you can increase that
- to 2000, 3000 or even 4000 PPM with some degradation of phase noise
- and temperature stability. Similarly, 3rd overtone crystals can be
- reliably pulled 100 PPM and 5th overtone crystals can be reliably pulled
- 40 PPM.
-
- How do you do this? Build an LC Colpitts oscillator at the frequency
- of your crystal (get it within a few %). Now, insert the following
- circuit in series with the
- emitter of the transistor: the crystal in series with the tuning diode
- in series with an inductor which resonates with the diode at the xtal
- frequency when in the middle of the diode's tuning range. Finally,
- install a shunt inductor directly across the crystal such that it
- resonates out the C-zero of the crystal at the crystal frequency.
- C-zero is typically 5 pF. Make sure this inductor has a high enough
- SRF (i.e. >> xtal frequency). Note that the finished oscillator has
- 3 inductors.
-
- If you have starting problems, you might have a VHF parasitic oscillation.
- The old trick with a ferrite bead on the base or collector will fix this.
- A 2N5179 is a good transistor to use.

- Right. How are you going to compensate the owners of closed repeaters - and
- remember that, according to the FCC, _ALL_ repeaters are closed - for the loss
- of their investment of time and money in building up their system? Remember
- that, ESPECIALLY in Southern California, the hams that built their systems on
- 440, often at greater expense than they would have had if they were on 2, not
- only for the repeater but also for their users' radios.
-
- Any coordinating body that tries to take away folks' coordinations without a

-
- Right. It may get them $500 instead of $250. Further, why should they trust
- that their investment in all new gear, not only for the repeater but also for
- the users, won't be similarly thrown away by the coordinating bodies?

-
- I don't claim that a coordinated repeater - open or closed - or its users own
- a frequency. I do claim, and the FCC and courts back me up, that the trustee
- of any repeater can legitimately prevent anyone he desires from using HIS
- STATION! IT'S THE STATION, STUPID!
