    Are there reverse beacons for SSB? I've seen them for digital modes, I'm not sure if there are CW/RTTY/SSB ones.

    Just curious if the signal strength for CW on the same band/frequency might vary if it were PSK, etc.

    Its a great tool and a great service. I like not having to hunt down so many bits of info that are available but spread over the internet--its all in one neat place. And for those (like me) that don't understand all the minutae of the propagation stuff--practical to saying '40m NIGHT: POOR' is good too. Its not 'guaranteed' to be poor, and people should still try it anyway (not expecting much). Perhaps a fluke in local conditions changes something, like a weird skip/thunderstorm/etc.

    Many thanks for it for the tools. Very much appreciated.

    Possible alternative to ARRL's Handbook explanation of HF Propagation? Video doesn't directly say it... but if it can affect Auroras and Earths Magnetic Field.... then...???

    My personal theory is that these magnetic explosions form cavities that are large enough to form an RF cavity that can absorb and re-radiate HF signals. This would be the mechanism that allows HF signals to appear to Reflect/Refract back to Earth. The more of them there are the more the band is "Open".

    Well fellas, I refer to the website several times a day and find it reasonably accurate more often than not. It is a great baseline to get an idea what's going on. Just getting on and calling cq is good too. It's another useful tool I appreciate very much.

    Thanks Biz, keep up the good work!

    After all this discussion over the past couple of days, I decided last night just to try 10 meters for the heck of it. As I was tuning around, I noticed a CW beacon on 28.299 ... K6 ... K6FR something /B. I can't remember the call now... But was surprised that just as the sun was going down that I could hear a California station on 10 meters, when all indications say that 10 meters sucks. So... Even I was proven wrong! :)

    I try and run WSPR across 40-10M when I remember to, before I start working the bands. This gives me a near real time propagation report of whats happening. If I dont run WSPR, I throw all caution to the wind and start transmitting. I have stopping relying on bandconditions.com as I feel its not a reliable source, and neither is the prediction graphic in this site.

    There's an old saying: If nobody transmits and everyone listens, every band will sound dead.

    ----

    I think the real issue is.....expectations.

    It used to be that practically all new hams came up through the Novice ranks, using simple gear on 80 and 40 CW. Their expectations were pretty low - a simple rag chew with someone 100-500 miles away was a big deal! Other bands and modes, and better equipment, came later in one's amateur radio "career".

    That's all changed now. Many amateurs come into the ranks via UHF/VHF and then 10 meters - all voice. Their idea of HF is what's above 10 MHz, not below, and they expect world wide DX with simple antennas round the clock. When it doesn't happen, "HF is dead".

    This is exactly the progression I've gone through, after getting my license in 2013, and then advancing to General in 2014. The conditions have changed a lot since even just then, and it's become more difficult to make contacts. I'm certainly not giving up. Infact, I recently got an FT-817nd and am learning CW so I can work the radio waves anytime I feel like it, rather than being tied to SSB on a 100w rig in my shack. I certainly hope people don't give up. I do know that if I was a technician, and tried 10m now without any luck, I might never have thought to go one to General class without someone showing me what it's like. Sure I've taken the easy way into the hobby, but I love it now...not sure that would have happened if they hadn't removed the code requirement. That said, more devoted elmers would be helpful for sure. Even for me, someone who already has a touch of experience. I can try to be an elmer myself, but could really use more people passionate about helping other hams too.

    I'd suggest also trying Fldigi (a freeware) so you can experiment with other digital modes, and RTTY as well. Some people prefer these methods for the ragchew element that JT65-9 doesn't allow for. I've had a lot of fun with PSK and RTTY. With conditions lately I am lucky to call into a 20 or 80m net within the same timezone and be understood. Last year seemed a lot better--hope it gets better soon!

    The QRP side of the FT-817 makes it a lot more challenging, unless you have a really good antenna and/or an amp attached. But it looks like a good rig and I wouldn't mind having one :)
