Hello Gents
I would like to request a "somewhat" consistent L and / or S mode availability on AO- 51. A recent post by John-K8YSE correctly explained that long term L/S availability is almost counter productive. If we define that by the number of operators to pass ratio. There are a few of us L/S holdouts mostly from AO-40 (sobsob). If we could plan that for say three days (or whatever) at a given date we can expect those modes, and be ready. Right now it appears to be a month to month variable decision with nothing definitive. If there were more availabilty and chit-chat about L/S modes it might inspire others to try it. AO-51 is the only testbed for varied L/S modes. The only way I have for "tweeking" my S band gear is to put a -35Dbm signal source at the end of my driveway and tweeking my equipment and antennas. Real world evaluation is always the proof of success.

Bob, I second that! Right now I'm trying to locally sell my 2 K5GNA downconverters and seriously considering getting rid of a FT736r with the 1.2GHZ module because of the inactivity. My FT847 is all that gets used. The last local flea market this year is 2 weekends from now and then I have to think about doing an eBay.
A 3 or 4 day session on L/S, U/S or V/S once a month allows for experimenting and tweaking in addition to trying to work 1 or 2 of those days into your other commitments.
Thank goodness for baby monitors and older cordless phones so that I can periodically scan the horizon to check out the K5GNA's :-)

I would vote for some sort of return of that if possible.

Dave,
I see you CCed the ao51-modes address. They are always looking for input for both new and old but popular modes.

Actually I just hit "reply" so it wasn't a concious decision!

I like more a rotation of the modes week by week so we can prepare use to the mode. And, please, less packet radio.
Please more packet. John

Yes, you have my vote. More frequent rotation of modes L/S, V/S or U/S. Ron n6paa

Hi Bob W7LRD
Instead to use a -35 dBm signal source why you don't try to receive the Sun-Noise ? Using my 4 feet parabolic dish and an overall Noise Temperature of 75 kelvin (1 dB NF) of my receiving system with 50 kelving from the cold sky yesterday I got 3,5 dB of Sun-Noise with the actual 72 sfu (Solar Flux Units ) which is a very low value of Sun activity.at 2800 MHz 10.7 cm Using the program NOISE.EXE this metod allow you to compute if the Sun-Noise level that you receive is in agreement or not with the receiving parameters of your receiving system i.e. it is a small radioastronomy exercise and a more accurate method than using a Signal-Source. In a separate email I have sent to you the progam NOISE.EXE The site where to get daily the Radio Flux in sfu at 2800 MHz 10.7 cm as requested by NOISE.EXE is:
