When should I start paying close attention to 6m? time of day, >month...etc. Complicated question #1: I monitor 6m whenever I can. I have worked openings from dawn to well into the night. Worked Hawaii first time at 10pm. You can get backscatter at dawn. It just depends. >2. What conditions should I watch for on >http://www.sel.noaa.gov/today.html that indicate 6m may be open? Complicated question #2: - around the solstices you get sporadic E (Es), which is good for stateside. - around the equinoces you get transequatorial Es, which opens up to south america. - at the top of the sunspot cycle (high SFI), you get F propagation. - if the sun acts up (coronal mass ejection) you can get aurora. - you can work meteor scatter during a major shower. Sometimes a high A-index can be a good indicator of the possibility of an opening. There is really no good reliable indicator for Es - thunderstorms and comet debris have been hypothsized, but as far as I know, nothing proven. A better site to monitor might be one or both of these: http://dxworld.com/magicband.html http://dxworld.com/50prop.html These post real time spots of contacts and indicators (like commercial broadcast signals). You can also keep an ear on 28.885. DX Summit spots are useful because you can see what is happening outside of your area. Recently, I watched an opening to VP8 go across north america - I started monitoring around the VP8's spotted frequency, and it paid off; but if I had waited for a local spot, I would have missed it. >3. Where is the action (what freq(s)) for : CW, PSK and SSB? (SRI to >have to ask, lost the notes I made last year) I can't tell you about PSK, but basically you get DX SSB from about 50.105 and up - 50.110 is the "DX calling freq" but DX could be anywhere. Domestic calls on SSB are above 50.125. CW is everywhere - in general, domestic CW is above 50.125 and/or below 50.100. DX CW could anywhere above 50.080. The reason CW is everywhere has more to do with shifting band conditions - a station will call on one frequency and change modes as conditions improve or deteriorate. I have more than once worked a station SSB and then returned a few minutes later to the same freq to work that same station on CW. I have also been calling on SSB and been answered on CW - time to grab the key to complete the contact! That said, most "pure" CW will start at 50.099 and grow down to 50.080 as needed. I can recommend two resources - first, "Six Meters, A Guide to The Magic Band" by Ken Neubeck, WB2AMU is definitely a must (from http://www.wr6wr.com/). I can also recommend, if you really want to stay current, "Six News" from the UK Six Metre Group (see http://www.uksmg.org/ - also a great web site!). hope all this helps a little! - 73 - jeff wk6i >73, Rod N0RC >Ft Collins, CO Jeff Stai Twisted Oak Winery LLC Email jds at twistedoak.com Amateur Radio WK6I ROC Web Page http://www.rocstock.org/ ++++++++++++++++
