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.

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
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.

There have been numerous updates, and the text transfer has been updated to make it more adaptable for use to insert blocks of text for broadcast. All the other functions of the BSR and FIX apply to the text function. If you were tasked with sending the participants of a net a rather intricate set of instructions, taskings, or specifications, and had to be sure each member had received it properly, you could spend a major part of an hour with requests for fills or repetitions, words phonetically, groups, or numbers. With easypal, you get what you get on the original transmission, and you send the BSR (Bad Segment Request) and the sending station sends the FIX file containing only those segments. Each member receives benefit of any bad block that they missed in a FIX file sent to another member, since it is a broadcast (non-connected) protocol. If you were involved in dial-up file transfer in the 80s, when text files were "captured" you will remember that it took as much time to capture a space as it did a letter. Transfer protocols were created the compressed ASCII on the fly to improve through put, I seem to remember J-modem, I-modem, y-modem and others that had the compression routines built in. I remember using a shell on ProComm Plus to allow choosing up to 14 different transfer protocols, dependent on the type of file you were transferring. I had at least 9 options available on the BBS I ran from the late 80s to the mid 90s. If Easypal can send a perfect high resolution picture in a 20K Wave file, you can imagine how small a 2 page document would be when converted to binary, data digitized into a wave file then sent in this manner to assure error-free reception. The repeater function allows the file to be sent to a central repository then retrieved individually by the members who could retrieve the file list. The program is getting very polished, and has great potential. I don't know if it is getting much exposure in all regions, but it is a valuable tool for the toolbox. As far as acceptance, MARS is a fairly diverse group of folks. Some are up in age, some are retired and homebound, some are fit and ready for deployment at the drop of a hat. Since there are requirements for continued membership, participation requirements, reporting requirements, requirements for pulling NCS and ANCS, requirements for NIMS compliance, now the requirement for a General or higher license Then you can see that the members have to meet certain obligations and benchmarks to continue to be a member. With this in mind, the program has some fairly receptive members, who wanted to go further in their service in, and understanding of the art of communications.. Most of them are quite willing to try something new. We haven't spent the degree of time on Easypal as we have with MT-63. But with each region having up to 10 one hour long nets scheduled each day, and each net has the requirement for some sort of training, and many members are uniquely qualified in one aspect of the training or another, it becomes fairly easy to see how a new mode can be introduced, explained, setup and operation help given, and results seen within the course of an hour and in an interactive manner in a disciplined net structure. Is MARS the silver bullet? Hardly. It has it's growing pains as much as any organization. In Amateur Radio, if there is a community that has 3 Amateur Radio operators, there will be 4 opinions on every subject and pretty soon there will be the need for 5 repeaters to be established so they can communicate with their "group". We all can key the Mic, but many times, as "communicators" we show that we can send out a signal, but actual communication is not often what results. The organized format of MARS, the requirements, continuous training, forward looking (not driving the car by only looking through the rear-view mirror), the disciplined net structure. All of these things help form a group that is dedicated to the art of emerg

The FCC rules are antiquated. Sending anything other than voice or image is illegal there if you use only one sideband. However, if you use both sidebands (B7W, B8W or B9W), any content is legal. 73, John KD6OZH - Original Message - From: Rick W To: digitalradio@yahoogroups.com Sent: Friday, March 27, 2009 13:56 UTC Subject: Re: [digitalradio] Easypal in MARS Although Easypal is currently the primary digital SSTV program , it also can be used to transmit any kind of data.
