RE: [digitalradio] Easypal in MARS
Howard, I am a member of Army MARS in the state of Georgia. Actually, I should say Region 4 MARS, as we are now under the Region concept and are merging into a Tri-Service organization. So far, AF MARS has completely revamped their call-sign structure to adhere to FEMA Region numbers. and all Navy/Marine Corps guys are Zeros. Don't ask me why the zeros are leading the pack; they seem to be immune to change.

[digitalradio] Re: WSPR power levels
The odd power ratings are often caused by (PSK) QRM. I even copied stations with 0 Watt... So not all spots in the database are necessarily correct. It also happens that a locator is decoded, but that it turns out that such a station is in the middle of the ocean.

In that context, Weak Signal has traditionally meant that the signal at the receive end of the QSO is at or below the noise level.

[digitalradio] WSPR power levels
I note the comments about people running high power. As I understood the original idea of this mode it was for very low power transmissions. That is the power applied to the transmitter, not the radiated power from the antenna. Bonnie you are not correct. WSPR was intended to see what could be done with low power, not with 100watt transmitters, which we know will reach around the world. The fact that people on EME may use high power has nothing to do with WSPR, you are confusing the argument. Yes on 144EME I will use high power, and a high gain array, but you are trying to overcome a lot of distance and a lot of noise, however on 1296 I can use 60watts and still see my echoes.

[digitalradio] Earth-Venus-Earth using CW and SDR
The reception of Amateur Radio signals bounced off the planet Venus is an impressive acheivement details of which can be seen at http://www.southgatearc.org/news/march2009/eve.htm It was done using the oldest digital mode CW coupled with modern SDR techniques. A video showing Karl Meinzer DJ4ZC, Freddy ON6UG and the 6 kW 2.4 GHz amplifier used to achieve Earth-Venus-Earth (EVE) can be seen at http://tinyurl.com/EVE13cmAmp The 2.4 GHz amplifier will be used by Radio Amateurs to sent signals to control the P5-A Amateur Radio Mars spacecraft. On its journey to Mars it will initially swing by Venus.

Weak Signal = Received signal strength levels that are close to or partially embedded in the natural noise. QRP = Reduce Transmitter Power QRPp = Very Low Transmitter Power 73 Bonnie KQ6XA
Re: [digitalradio] Unintended Consequences: Recent FCC Order on Repeaters
I suspect I know what you're thinking of :)... probably the same thing I was thinking of when I read the Order: A digitized voice mode where the transmit channel data rate is sufficient for transmitting at least twice what is required for the compressed voice; packetizing the voice into something that requires less than half of the available bandwidth, an having a non-repeater re-transmit the signal in the intervals between the packets it receives. Setting a 'has been retransmitted' bit in the packet would prevent double packets messing things up on receive if the receiver hears both signals. Sounds like fun. Or, if that wasn't what you were thinking of, sounds like there may even be *more* fun out there. 73, Paul / K9PS expeditionradio wrote: The FCC recently posted on Order clarifying what it believes a repeater is. Due to the law of unintended consequences, while this recent FCC order closes one small perceived loophole for D-Star and P-25 signals, it simultaneously (pun intended) affirms something else... the existence of an opportunity for other type(s) of digital voice relay systems that will absolutely not be considered repeaters by FCC! I'm not going to spill the beans on exactly what RF digital methods or other techniques this speaks to, but it has far-reaching ramifications for wonderful new developments in ham technology on HF/VHF/UHF. I will say that I'm quite gleefully watching what happens next... this is going to be fun! 73 Bonnie VR2/KQ6XA

RE: [digitalradio] Easypal in MARS
Paul, Glad to hear Navy is giving it a try. The rest is grossly off-topic, but I feel the need to expand my understanding. On the Zero, it is a sore point across services, as is the full call debacle on initial check in that I believe came from Bo's influence. I can declare abbreviated calls are authorized, before I establish ANCS, and take 5 to 8 check ins per minute with out duplicate transmissions. In many cases, using abbreviated calls, I can get an entire working net of about 20 stations, establish ANCS, make the call for emergency or priority traffic, have ANCS make the same call, and have 54 minutes for training, administrative business or emergency net operation. Since we have to use full phonetics (Our prefixes are more complex than NNN), and we never fall back to Abbreviated Call Signs (Our prefixes are more complex than NNN), and we never give a call sign non-phonetically (our prefixes are more complex than NNN), and we use FEMA Region designators to be able to geographically determine the effectiveness of the net (our prefixes are more complex than NNN0) We find that the attempt to require full call signs on initial check in to be a surefire way to create Chaos. Also, in preferring the concept of training the way we would operate in an emergency, we have generally found that requiring full calls to NCS, when the net can only have ONE NCS is as well thought out as being asked if we want fries with our fries, when we just order fries. One day, I may be fully expanded enough in mind and maturity to fully understand the full call requirement. I'll bet you guys are still laughing about that part of the new voice SOP.

Re: [digitalradio] Easypal in MARS
I liked it better back in the early 1960's when I was in Navy MARS with the call N0YUI. Of course, today that has been reissued as a ham call.
