RE: [AMRadio] Diversion
I had a G-50 a couple years ago with the same problem. The internal reduction drive assembly was slipping in some places. I squirted some degreaser inside the bigger shaft, and it worked much better. It started slipping again when it dried, but after squirting a little more in there, the slipping was gone. It might not work all the time, but it did work for me.

After stuffing the filter capacitors and replacing a couple of capacitors in the cathode circuit of the speech amp/preamp combo the G-50 came to life. However, I find now that the variable capacitor on the receive VFO is having turning problems. It's one of those geared internally capacitors with one shaft inside another one. I guess the friction clutch or whatever makes those things tick is worn out or maybe oily. Does anyone have a solution for such a problem, other than replacing it?

RE: [AMRadio] antenna tuners
I was thinking of putting an add-on kit on my vertical to make it resonant on six meters, but now I'm thinking that might be a waste of time and money if I can tune the antenna on that band with my tuner and get a low swr at the transceiver. It's a tube rig, so it probably doesn't need a real low swr anyway. Any thoughts or recommendations? Thanks, Al, WA2AS -Original Message- From: Gary Schafer [mailto:[EMAIL PROTECTED] Sent: Thursday, April 20, 2006 11:08 AM To: 'Discussion of AM Radio' Subject:RE: [AMRadio] antenna tuners Hi Alan, No need to go away! You will get lots of good info here and asking / discussing is how to understand. As to resonant antennas, it makes no difference in how well they radiate. Resonance of the antenna is not required. SWR is not all that bad either as long as the transmitter sees a match, especially the solid state rigs. When open wire feed line is used there is usually very high SWR on the feed line. If you connect 450 ohm line to a half wave dipole which is normally in the 50 to 70 ohm range you have high swr on the feed line. And no, high swr on a feed line will not cause it to radiate. What causes feed line radiation is an unbalance between the two wires in the feed line. High SWR on coax line will cause a little more loss in the feed line due to the higher currents involved across the lower impedance of the coax. That is why when using open wire line that is 400 to 600 ohms, there is much less loss. The same power across a higher impedance means less current and less current going through the feed line wire means less power loss. An antenna tuner just matches the impedance seen at the transmitter end of the feed line to the 50 ohm transmitter output. If there is high swr on the feed line, any power reflected from the antenna is not wasted it is just re-reflected back to the antenna and eventually gets radiated. At HF even fairly high swr on coax lines does not cause excessive loss. 73 Gary K4FMX -Original Message- From: [EMAIL PROTECTED] [mailto:amradio- [EMAIL PROTECTED] On Behalf Of Alan Beck Sent: Thursday, April 20, 2006 5:45 AM To: AMRadio@mailman.qth.net Subject: [AMRadio] antenna tuners I don't believe in them. If you can't resonate your antenna, then what are you doing? If you use a tuner, you are creating a voltage divider effect that creates a reactive load in your shack, to ground that makes your antenna feed line + radiating elements. Over the years, the importance of having at least a 2:1 match with at least 1.5:1 some where in the the antenna design. Proper antenna design for your favorite frequencies is the best choice. I currently use a multi-element dipole to cover 80,40,20,15 and 10 meters. I just use a VSWR bridge and back off the power when the SWR rises close to 2:1. I am not saying my answer is the best, I am only stating my opinion. Just like microphones in the sound work I help out with at church. If they are not singing into the mic, I cannot fix it without creating a gain structure that is sucking up to feed back You need to fix your problems at the source. I our cases, it is resonance of your antenna, by some means. Even my hamstick on my jeep does great due to attention to resonance. 73 Alan VY2WU __ 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 __ 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 The information contained in this message is confidential and intended only for use of the designated recipient(s) named above.

RE: [AMRadio] Bad Static Problem
Update on static problem: Yesterday, I tried both a 6 foot wire and my Ringo Ranger 2-meter antenna (just the center pin of the PL-259), and the static is still there, but not as strong as with the hf vertical. I thought at first that I tracked it down, because I found that the dimmer switches for the recessed lighting in the kitchen were making all kind of noise at the very low frequencies (peaked up at 170 kHz). After shutting the lights off, I found that that noise went away, but the noise on all the lower hf ham bands was still there just as strong. It doesn't have any sharp peaks or anything, but there are a lot of places where it does kind of peak up, although it is very broad. The freqs where it seems to peak are (in MHz): 2.4, 2.7, 3.37, 3.55, 3.9, 4.2, 5.0, 6.2, 6.6, 7.2, 8.0, and 8.7. Above that, it starts to roll off quite a bit. The peaks might have something to do with the resonance of the antenna, but I'm not sure. I was using the hf vertical when I measured them. Any more thoughts? I'm thinking probably power lines, but maybe I should try a battery-operated radio and turn off the power to the whole house before I come to that conclusion. -Original Message- From: Bob Macklin [mailto:[EMAIL PROTECTED] Sent: Tuesday, February 01, 2005 1:53 PM To: [EMAIL PROTECTED]; Discussion of AM Radio Subject: Re: [AMRadio] Bad Static Problem Last night I had HIGH static on both my HF receivers.

Thanks for all the info. I guess the next step is to try an indoor antenna made out of a piece of wire, and see what happens. I don't have a portable short wave receiver, but I do have a Kenwood R-2000, which I think, works on 12 volts, so I might be able to try it in my truck with a piece of wire for an antenna. I sure hope it doesn't turn out to be an uncooperative neighbor.

Noise of the specific variety propogates according to the length of the wave. IF it is power line generated and you hear it on 160 and 80 strong and weaker on the higher bands, then it will be far away and carried by the line. The closer you get to the source the higher frequencies will get strong as well. Equipment for finding the specific location of power line noise will be tuneable from 30 to 300 MHz, AM. The closer you get the higher in frequency you should go until reaching 300 MHz and using a beam antenna you can pinpoint the pole where the noise is. Check around your house for sources of noise that has been suggested, TVs, VCRs, your stove (if it has a microprocessor) Satellite receiver (mine has broadband noise), doorbell transformer, your water heater, water softner, etc. If it is in your house you should be able to hear it on the higher frequencies but you say it is not strong there. Remove the antenna connection to your receiver and see if you hear it, if not attach a short piece of wire. Should you not hear it with the short wire, it will be located in your neighborhood or down the street up to a mile or more away. Then you should check your neighborhood with a hand held portable. If you own a portable or scanner that receives the aircraft band, then make up or purchase a 3 element VHF beam and use a short piece of RG 58 to attach it to the portable. Start at lower frequencies and as the noise gets louder, switch to the higher frequencies until you locate a couple of poles. At that point, copy the numbers on the poles and call your power company. Document the call and who you speak to in case they are not very responsive. Sometimes it takes a few days to a couple of weeks for them to fix a problem, be patient and give them adequate time. If, within about 6-8 weeks they have not contacted you, call again and document every call. If they do not respond in about 3 or so months, then send a complaint to the FCC with copies of your documentation. This is all true if the noise is coming from the power company. If it is a neighbor, then notify them verbally, be very nice, but do document. Recently the FCC sent a Notice of Apparent Liability to a man and woman who owned an electric wheel chair and the charging circuit was generating noise. The ham installed filters and the owner removed the filter. After several attempts to convince them to fix the problem and they would not, the ham sent the information to the FCC. The FCC made several attempts to convince the owner and when they would not address the problem the FCC sent the notice. This is probably more than you want to know, but it illustrates where some of these crazy noises can originate. 73 Jim W5JO - Original Message - From: Schichler, Alfred [EMAIL PROTECTED] To: AMRadio@mailman.qth.net Sent: Tuesday, February 01, 2005 7:48 AM Subject: [AMRadio] Bad Static Problem I just started getting an intermittent noise problem on several bands that runs from s-9 to about 20 over.

I was wondering if there are any nets, or just parts of the 75 or 40 meter bands where I could find anyone on low power AM, preferably controlled-carrier, screen-grid modulation. I recently got a DX-40 / HQ-100 AM Station on the air, for nostalgic purposes, but it seems like the only AM stations I usually hear are ones with high-power, high-quality plate modulated AM, and I don't want my puny signal to be just lost in the crowd or ridiculed. (Not that that would necessarily happen, but it seems like a possibility). I haven't listened at all hours of the day or anything, but I haven't found what I'm looking for. I would appreciate any info on this subject. Al, NE2D
