We've managed to have a quiet and reasonable discussion on the ARRL's policies and their effect on ham radio without the obvious problems of the rec.radio.amateur.policy list. At this time, I'm confident that there is enough interest in the list that it will continue to operate (unlike the last three ham-radio mailing lists I started). Thus, I'd like to open the list to packet-radio redistribution.

Makes sense it might occur up there above 15 meters, I have had similar problems. My diagnostic suggestions: 1. Try a different antenna, or use a dummy load to see if the same ALC readings occur. If not, sounds like RF. 2. If above no help, carefully check the mike cord for loose ground, etc. Might even just add a new mike cord and connector. Don't forget to check the connections inside the 430, that can do it too. 3. Try a different length of coax to the tuner, or check the coax carefully for loose ground, etc. 4. Create a different ground system. For 15 or 10, use a quarter wavelength of wire thrown out on the floor and connected to your ground terminal. See if this changes the situation. Implicates grounding problems. 6. Your antenna may just be radiating a whole lot into the shack. Think about this, look at the likely pattern, how close the antenna is to the shack, lack of balun (?) or other feedline radiation. If this ends up the direction, check antenna handbooks or feel free to write to me and I have lots more suggestions. Yeah, it has happened to me a lot. 73 Clark WA3JPG ------------------------------ Date: Sat, 26 Mar 1994 14:22:29 GMT From: ihnp4.ucsd.edu!usc!howland.reston.ans.net!newsserver.jvnc.net!raffles.technet.sg!ntuix!ntuvax.ntu.ac.sg!asirene@network.ucsd.edu Subject: Ham-related mailing lists To: info-hams@ucsd.edu Hi, Can someone post a list of all HAM-related mailing lists that we can subscribe to?

To: info-hams@ucsd.edu I am considering installing a new antenna in my vehicle and roof-mounting it. Of course, I'll need to make a hole in the roof, so the other day when at my local dealership I asked them what affect that might have on the vehicles value at trade-in/selling time. Their response was that it would lessen the value of the vehicle by $500-$600. This seems a bit steep for one hole in the roof (whether it's plugged or the antenna gets ultimately sold along with the vehicle). Is this estimate anwhere near accurate? What kind of depreciation (if any) should one really expect when selling/buying a used vehicle which has had a roof-mounted object? mla -- Mike Abelson - Network Operations Center abelson@rpi.edu Information Technology Services usergzn0@mts.rpi.edu Rensselaer Polytechnic Institute Packet: kb2kyz @ wa2umx ------------------------------ Date: 26 Mar 1994 14:18:15 GMT From: ihnp4.ucsd.edu!agate!howland.reston.ans.net!vixen.cso.uiuc.edu!prairienet.org!k9cw@network.ucsd.edu Subject: Hole in car roof: Affect vehicle value?

When the cars were sold, no one even seemed to notice the hole plug (I would suggest removing the antenna before selling it). If you want the best VHF or UHF performance, that is where the antenna should be. If, on the other hand, resale value is the issue, I suggest that you go with a through-the-glass antenna so that there is no hole. 73, Drew -- *-----------------------------*-------------------------------------* | Andrew B.

If your RF amp is working at about 10 MHz or less, you probably won't notice much improvement. Above that, a simple test is to listen to the noise with the antenna connected, but no signal present. Disconnect the antenna and see if the noise drops. If it does, then the limiting factor is the noise from the antenna, and not the noise generated in the front end transistor. If it DOESN'T drop, then a lower-noise transistor is called for. You can get real fancy with noise figure measurements if you want, but for ordinary ham purposes, this test will tell you what you want to know. ------------------------------ Date: Mon, 21 Mar 1994 12:58:53 GMT From: ihnp4.ucsd.edu!usc!howland.reston.ans.net!pipex!uknet!EU.net!relay.puug.pt!news.inesc.pt!animal.inescn.pt!ciup2.ncc.up.pt!news.ci.ua.pt!etjfonte@network.ucsd.edu Subject: QSL info To: info-hams@ucsd.edu TNX for reading.

Exchange signal report and progressive serial number starting with 001. Details appear on page 112 of February QST. NNNN /EX ------------------------------ Date: (null) From: (null) SB PROP ARL ARLP012 ARLP012 Propagation de KT7H Solar activity remained very low last week. Geomagnetic conditions ranged from unsettled to active, with a few quiet periods. The most disturbed days were March 17 and 21 when the A index was above 20. March 20 was the most stable day, with the A index at 8 and the K index dropping all the way to zero during one period. For the SSB WPX contest this weekend look for a slightly rising solar flux, possibly reaching 100, with fairly stable geomagnetic conditions. 20 meters should be the best all around band for worldwide DX during the daylight hours and into the early evening. Unfortunately, the short term rise in solar flux should reach a maximum of only about 100 early in the week, and then drop back to around 90 by April 5, when a recurring coronal hole is expected to raise some havoc. April 4 through 7 could be very disturbed, if conditions from the last solar rotation four weeks earlier are any guide. After the drop in solar flux it should increase again to around 105 by the middle of April. Sunspot Numbers from March 17 through 23 were 30, 24, 11, 11, 26, 35 and 32, with a mean of 24.1. 10.7 cm flux was 85.1, 87, 89.1, 88.6, 90.7, 91.1 and 91.8, with a mean of 89.1. The path projection for this week is from Sweetwater, Tennessee, which is between Chattanooga and Knoxville, and United Arab Emirates. 80 meters should be open from 0030 to 0230z, and 40 meters from 2330 to 0300. 30 meters looks good from 2300 to 0330, and 20 meters from 2000 to 0030, with the best time from 2230 to 2330. 17 meters should be open from 1430 to 1930. 15 meters does not look very promising, but check from 1700 to 1830. 12 and 10 meters do not look good at this time, but there is a very slight chance of a 12 meter opening from 1600 to 1900, and on 10 meters around 1800 to 1830.
