A bit of humor... please no flaming or arguing over this. Life is short. Enjoy radio. 73, Mark W1EOF ~~~ Dateline, Washington, DC The FCC today took what they described as an important new step to reduce QRM on amateur frequencies by setting standards for voice speeds. The docket #200-4U will become official in the Part 97 amateur regulations effective April First. Citing frequent complaints about long, boring conversations on the ham bands, especially 75 meters, the Commission moved to impose a new standard on voice operations requiring all conversations to be at a speed of at least 200 spoken words-per-minute. The Commission in its ruling was especially critical of what they called long winded, often endless conversations by old men talking about their prostate problems and other needs to get up and go to the bathroom several times during the night. FCC staffers say they have personally heard conversations about nothing that went for hours and tied up frequencies that could be used by faster talkers. Official Observer stations have received instructions to listen to suspect conversations and count the number of words-per-minute spoken. Those QSOs which fail to meet the minimum speed requirements will be noted and the operators involved will receive Official Observer Advisory Notices encouraging them to follow the rules or risk receiving notice of apparent violation citations from the FCC. Some hams in southern states complained the new regulation will impose a burden on them because they naturally talk more slowly than those up north. They are suggesting that frequencies be set aside for slow speed discussions concerning favorite countrymusic artists (particularly Don Williams), NASCAR, huntin' and feeshin' (particularly bass and brim). FCC says it may consider that in future rulemaking. In a separate press release, the American Radio Relay League said they are also concerned about two-meter operation where little is discussed except full quieting and items to be picked up on the way home. The League said that sort of thing is boring and is usually spoken very slowly as well, far below the 200 words-per-minute minimum. The League suggested conversations on how to help raise more money for League activities would be especially welcomed and will be encouraged. Future issues of QST will contain special pull-out sections containing recommended topics for on-air discussion to brighten up QSOs. __ AMRadio mailing list Home: http://mailman.qth.net/mailman/listinfo/amradio Help: http://mailman.qth.net/mmfaq.html Post: mailto:AMRadio@mailman.qth.net AMfone Website: http://www.amfone.net AM List Admin: Brian Sherrod/w5ami, Paul Courson/wa3vjb __ Do You Yahoo!?

My remarks deal mainly with those who choose to turn a nice old receiver or transmitter into a 'piece of (non-functioning) art' instead of using it as a radio. It really has nothing to do with age, more mentality. You really can't do much with a Monet other than hang it on the wall or use it as a beer tray. But IMHO those who get nice old cars, radios, or whatever else simply for the bragging rights and not to use and enjoy are better suited to stamps, pantings, or other inanimate objects that don't require any interaction beyond staring at them. Besides, it's much more impressive to say I paid 4 million for this painting than to say I paid 4 thousand for this old radio. Who beyond other radio collectors would be impressed? In the end, you can use an SX-88 or KW-1 for a 30.06 target if you want to, no argument there. I'm far more impressed when someone has a nice rig and know how to use it than by how much they paid for it. Even moreso if they can fix it, or built it. It's strictly my opinion mind you, but I believe more BA folks appreciate a piece of gear for what it is and can do, not its potential value as an investment. Collins gear is some of the best gear ever made, yet look at how many real 'hands on' radio folks think less of it because of the ridiculous 'mine's bigger than yours' collector mentality of a self-absorbed few? Age isn't the issue as far as I'm concerned. It's attitude. God Bless anyone who makes it to retirement and actually has money to spend on whatever they enjoy.

Re: [AMRadio] Shorting stick
I wouldn't use wood for an insulator. Its insulation properties change drastically depending on the relative humidity. I have seen telephone poles light up quite nicely with 10K volts on them. PVC pipe (the white stuff) is a good insulator. To test it, put it in a microwave for a couple of minutes. If it doesn't get hot then you have a wonderful high voltage insulator to make your shorting stick. 73 n1fcu __ Do You Yahoo!? Tired of spam? Yahoo!

Re: [AMRadio] Broadcast transmitter
I have an rca bta-1r (just got it) and I wonder how much drive you need for the circuit as you have it? John (N1FCU) --- KC8OPP Roger S. [EMAIL PROTECTED] wrote: Rick, Here is what I did to bring the RCA to 160/80/40M. First thing is get a copy of the Radio Handbook by William Orr, W6SAI. This book has all the answers. I started by bringing the transmitter up on the freq the radio station used. I cleaned and repaired as required. I checked all voltages against the book, swept the audio section and made more repairs. When it works as advertised by RCA, then you can start to have fun. I removed the master osc board and built a box for the grid input circuit. I used link coupled coils that are switched in for each band and drive the grids with a Kenwood TS-520. The same band switch is used to changed the taps on the final tank coil. The winding data for the grid coils was borrowed from the 16th edition of the Radio Handbook. I did install a grid coil for 20M, but have never tried the transmitter on 20M, wishful thing I guess. The final tank that RCA installed was completely removed and I used the L coil for my tank. Vac variable caps were used for Tune and Load. I put the circuit together on the bench to find the right taps on the coil. Use a non inductive resistor in place of the tube that is equal to the calculated plate load and then a antenna analyzer connected to the output. This put me in the ball park and just some minor changes were needed when the tank circuit was installed in the cabinet. The cabinet measured 32 inches deep and 34.5 inches wide when I removed the meters and switches, just enough room to fit through the doors. I would guess that in the stripped down mode the cabinet still came in around 300 pounds or so. Hope this helps a bit, I will look forward to hearing your RCA on the air.
