Hello America and ships at sea,.. I just got a Kenwood R-1000 receiver and I was wondering if anyone knew what kind of antenna I could rig up for it. Can I clip something on to the stainless steel backstay and expect to get a signal? I'm watching the other ssb thread that suggests you can get a weather fax from it too. Thanks as always. Hello Ray, Sure, you can try the lifelines, the backstay, or a random length of wire you have handy. Try them all. See which works best. The downside of that sort of antenna is that it is likely to pick up a lot of unwanted noise as well as signals of interest. Of course, at sea the noise issue will be less. If you find reception is poor with these antennas, you can always use an antenna resonant at the frequency of interest (hopefully you won't have more than one or two of these) or you can use a simple antenna tuner. For reception only, the tuner can use very small and inexpensive components. Keep in mind that we're at the bottom of the 11-year sunspot cycle and high frequency propagation can be pitiful at times.

: Any sign yet of an upturn in the cycle? It's an 11 year cycle.... You can watch it on: http://solarscience.msfc.nasa.gov/predict.shtml The most fascinating place about it is at: http://www.spaceweather.com/ Today's sunspot number is ZERO! NO SUNSPOTS! Arrghh. Sure glad there's Skype...(c; Spaceweather can EASILY occupy an entire evening exploring. Canada accurately tracks the Solar Radio flux on 2.8 Ghz: http://www.drao-ofr.hia-iha.nrc-cnrc...sol_home.shtml So, from their prediction graph, it looks like a nice peak in 2012. This is perfect as that is the year my Socialist Security checks start rollin' in and I can stop working for all my money and live off the kids at Mickey D's flipping hamburgers. Who knows. I might just put W4CSC back on the air...(c; At night the only thing that's working for me on Winlink/Pactor is 80M. 80 and 160M act more like AM broadcast band than shortwaves. They're pretty predictable as a good nighttime freq with groundwave only on the sunny side of the planet. 40M up to 10M is what the solar cycle hits so hard. I have seen 75M SSB totally unusable for nets a few times. Of course, to become "net control" on an ARRL net, you must NOT own a proper ANTENNA or BIG LINEAR AMPLIFIER so you don't sound like you're talking on a wet string with 10 watts, no matter what the conditions...(c; I used to be active on the SC SSB net on 3915 many years ago. One night at net time you couldn't hear hardly anyone it was so bad. At that time, I was running an old Heathkit HW-100 SSB transceiver (tubes, cheap) and a home brew little amp I made out of some power company parts and a PAIR of 4-1000A tetrodes in a 7 ft tall old navy transmitter rack, about 4' wide. Using "minimum power to establish communications" that night meant running 6000 VDC at about 950ma on the little tubes. That's about a kilowatt, right?....(c; The AM station down the street ran 200W on 1260 at night in a 3-tower directional array over my house. EJ, the chief engineer and night DJ at the transmitter building used to call me and ask if I would hold off transmitting until he read the antenna current meters wildly moving around too far to fill in his log. He joked I had more current in his towers than he did...hee hee...(c; Those were fun days....no money, homebrew everything. I carried a melted 2' section of RG-8A/U coax into a ham club meeting and said they just don't make coax like they used to....my little amp melted it...(c; Larry "POWER is our FRIEND!" (Robert Mitchell, AAA Communications, paging) "You can tell when your ham station is tuned up, easily, by seeing how dim the lights are in your neighbor's house." - (me) |
