[future arguments against amateur radio deleted] Yes, you have made some good points on possible future attacks on amateur radio. Note that amateur radio is more like social security than like gun rights. It is a socialistic allocation of confiscated property. Its justification is for people to fiddle around with new technology at the government's expense and provide an alternative emergency communications network. Just like a park which can be used by FEMA to put up tents or play in, Amateur radio uses the radio waves. It has one-up on FEMA because it is private individuals who are responsible for maintaining their equipment which they can volunteer or allow to be coopted in the event of an emergency. Repeatedly, Amateur Radio has proven itself to be an effective means to provide volunteer help in emergencies. Even if the radio waves were one day to be regarded as property and not allocated loot as they are today, there would be a role for reserving a portions of the electromagnetic spectrum for this purpose for the same reason that the government needs military bases to defend its citizens. As for the FCC rules on Amateur radio, because it is more like social security where you sign agreements putting yourself under the auspices of the Federal government, it is most emphatically unlike gun issues in the current political climate. When you sign your license application and pass your test, you are promising to obey the laws as applicable to amateur radio. You are submitting yourself to a series of regulations that prescribe and proscribe your behavior which include some potentially Draconian penalties. One difference from social security though is that you're not tricked into joining it out of ignorance. Amateur radio licensees got into the service with both eyes open, putting it head and shoulders above most government activities that restrict human life. -- Chris Walker cwalker@zycor.lgc.com ------------------------------ Date: 4 May 94 23:15:58 GMT From: dog.ee.lbl.gov!ihnp4.ucsd.edu!usc!usc!not-for-mail@ucbvax.berkeley.edu Subject: Amateur Radio and Civil Rights To: info-hams@ucsd.edu yee@mipg.upenn.edu (Conway Yee) writes: [Intro deleted] >1) Nobody _needs_ amateur radio so we should feel free to ban it. >2) With the advent of cellular phones, amateur radio is outdated. >3) The only purpose for ham radio is by criminals who scan the > airwaves to keep track of police broadcasts. >4) Amateur radio emits radio waves which have been shown to cause > cancer so we should prohibit amateur radio as a public safety > concern. >5) Amateur radio antennas are liable to fall and injure someone. >6) Use CCR's to limit antennas.

People who depend on gov't comm nets, on the other hand, will never complain about the budget or power of FEMA, the FCC, etc. You'll never see anyone admit to these motives openly, but they will exist soon if they don't already. Prohibition movements have the same form whether one is trying to ban alcohol, or guns, or amateur radios. I give amateur radio another 15-20 years if current trends continue. The same for private aircraft. Private automobiles will probably last 30-40 years, but no longer. The future will not be pretty, unless we change course soon. It disheartens me to hear that the consensus among amateur radio types is that gun control is a good thing. It may come to the point where we need them to coordinate our opposition to the State, and they need us to guard their stations.

Amateur radio is a highly regulated communications medium, unlike internet. Radio operators are getting a favor from the federal government that is in their personal interest to maintain. The feds frequently treat them well too because they need amateur radio operators, even today. The typical individual who sticks with the licensing requirements of amateur radio, especially the advanced licenses, tends to be quite loyal to the central government operating out of Rome, er Washington. It makes a big difference when there someone is getting a major favor from the government when it comes to judging other activites thereof. -- Chris Walker cwalker@zycor.lgc.com ------------------------------ Date: 4 May 1994 07:51:40 GMT From: ihnp4.ucsd.edu!dog.ee.lbl.gov!agate!howland.reston.ans.net!EU.net!Germany.EU.net!Munich.Germany.EU.net!thoth.mch.sni.de!news.sni.de!nanette!norton!schro@network.ucsd.edu Subject: Batteries for Kenwood TH-78A To: info-hams@ucsd.edu In <2psn0m$h5n@apakabar.cc.columbia.edu> mrw13@namaste.cc.columbia.edu (Marc Richard Wollemborg) writes: >I finally decided on buying a Kenwood TH-78A and am now considering which >batteries to get with it.

The 7.2V/700mA came with the radio when i got my TH-78E. It's small and fits completely inside the rig. I mainly use it when i carry the 78 around. Good for listening but don't talk too much. The 12V/700mA doesn't make sense to me. It's too large and at 12V the current goes up to more than 2A, which is too much for 700mA cells. It's easy to kill a cell by reverse charge and the pack is sealed so you can't replace individual cells. You get a bit more power out but if the other side can't hear you at 2.5W it probably can't hear you at 5W. Get a better antenna instead. IMHO the 7.2V/1100mA is the best choice. I can chat all night long and then it won't go down all in a sudden. The charge circuit inside the 78 will only supply about 60 mA of charge current so it takes some time to recharge, but then you won't overload the little wall cube and won't do any harm to the pack even if you leave it on for a week. >There is also the BT-8 battery case which takes 6 AA batteries; what kind of >output (in watts) does this provide for and how long will it last? With 6 Duracell alkaline you get 6*1.5V -> 9V. Output power maybe abt 3.5W. I think those cell have a capacity off abt 1700mA. With 6 NiCd cells you get 6*1.2V -> 7.2V. The sticker on the BT-8 says: don't use NiCd. Of course i ignored that and got me 850mA cells. The only problem was that the cells were not charged inside the rig. I was too lazy to pull them out for charging and modified the BT-8 at bit. >Additionaly, how about batteries that fit the Kenwood but are made by other >manufacturers? I'm specifically looking for a "long-life, high-power" >battery. Any suggestions/recommendations out there? Thanks very much. Don't know any. Get a BT-8 and make your own pack. Then you can use any type of cells you want and also can access individual cells. I plan to get a set of those new NiMH cells that claim a capacity of 1200mA. >-Marc Wollemborg > 73 Django DL5YEC ------------------------------ Date: 4 May 94 19:49:29 GMT From: dog.ee.lbl.gov!agate!kabuki.EECS.Berkeley.EDU!kennish@ucbvax.berkeley.edu Subject: FT-11/41R PL Tone Problem: Followup To: info-hams@ucsd.edu Disclaimer: The following is for informational purposes only. Use at your own risk, and any liability from using this information is yours. --------------------------------------------------------------------- History: Those that saw my earlier post are aware that the Yaesu FT11/41R radios have a problem with the PL tone generation. If used without the optional FTS-26 tone board, the PL tones are slightly off in frequency, being too high. Solution: Yaesu has recognized this as a problem, as has issued a service bulletin TB9420 to deal with this problem. The fix involves changing the value of one of the loading capacitors used with the microprocessor crystal. The principle being that lowering the clock frequency will lower the PL tone. Yaesu's bulletin directs changing C2018 (33 pF chip cap loading the output of the inverter on the CPU) to 39 pF. Warning: Those of you contemplating this should be made aware that the chip cap less than 1/2 the size of the COG size chip caps -- I would not attempt this without a microscope and a FINE tip. Changing the capacitance to 39 pF did indeed lower the PL tone, but was insufficient to fix the problem. Only after adding another 7pF (total 46 pF) did the PL done fall within range of a local repeater. It may be that this particular situation was bad luck (i.e. high crystal, low caps, low reed on the repeater). Yaesu has started using the larger capacitor beginning with lot 13 (11R) and lot 12 (41R). If you have a problem with PL tones, and opt to return your unit, you may want to insist that they check the value of the PL after the mod -- they may have to put an even larger capacitor in there (e.g. 47 pF) I am happy to report, however, that the above mod has fixed the PL problem for me, and the local repeater now likes the 41R. Other than this minor (albeit frustrating) glitch, the 41R is a neat unit. VERY small -- less than 1/2 the size of the 530, and performs well for its size. The standard 4.8 V pack is compact, but keeps the power output to 800 mW on high and 200 mW on low, which may be a problem for those hard of hearing repeaters. Speaker audio is improved over the 530. Your mileage may vary. Related Item: The extended RX/TX mod for the 41R is identical to that for the 11R. -Ken ------------------------------ Date: 4 May 94 19:45:59 GMT From: news-mail-gateway@ucsd.edu Subject: Gun Owners ... never mind.d.7 To: info-hams@ucsd.edu I fired off a nastygram to the Gun Owner author and cc.'d his postmaster.
