well, i just found this under the user service agreement= 9) Determine your own precedence based on your current communications requirements for each pass. In general, all use is routine except for special circumstances. Typical Special usage is for demonstra- tions, and long term events. Priority usage may be for VIP demos or special one-time events. Use good judgment, being fair to all other usrs. To alert other users to your precedence/priority, Set your period and position comment as follows: STN CLASSPRECEDENCE PERIOD ICON POSITION COMMENT --- -- -- - Mobile/HTEmergency .2 min anyEMERGENCY Priority .5 min anyPRIORITY Special 1 min anySpecial Routine 2 min anyOff-duty,Enroute,...,etc Termnl Pkt* ALL X * 2 N/AShort BText Base StnsALL X * 2 House Off-Duty GPS Traker ALL X * 2 GPSxyz N/A so, i guess routine notification status will work.

ahoy amsat and wb4apr/ Bob, i believe i read, that to digipeat thru no-44, the status message in a th-d7a had to be ABOVE a certain "level". i leave mine on as status= SPECIAL. i cannot find that info now, but did run across something different=Kenwood D7 and D700's use the Mic-E format (Turn off any status text) from http://www.aprs.org/pcsat.html just after 'end of mission'.the SPECIAL status is listed as 'pos comment', not status text, in the d7a. what are the correct settings, in a kenwood th-d7a, for digipeatingpackets thru no-44 ? it seems someone got fancy with aprs-is-ce, recently, and now i amgenerating pop-ups, so i will have to remember to switch it back forearth packets. tnx, happy fathers day, robert k f zero g cn81 > Date: Sat, 16 Jun 2012 17:13:03 -0700 > From: engdahl at snowcrest.net > To: k...@arrl.net > Subject: MIC-E Notification > > Robert: > > Your tracker, KF0G-9 is sending MIC-E "Special" notifications as you > travel.

F-1 CubeSat is ready for its scheduled launch in July 21, 2012 from Japan. If everything goes according to plan, the F-1 CubeSat will be delivered to Japan by the end of June. Then along with four other CubeSats (RAIKO, WE-WISH, FITSAT-1 and TechEdSat) F-1 will be loaded onboard HTV-3 Kounotori transfer vehicle for integration with the JAXA HII-B launch vehicle. These CubeSats will remain aboard the ISS until September, 2012 when Japanese astronaut and radio amateur Akihiko Hoshide KE5DNI should deploy it into space from the ISS using the Kibo robot arm. F-1 carries two Yaesu VX-3R transceivers using 145.980 and 437.485 MHz. The FSpace team are offering the public a chance to send their name/ callsign and a message into space onboard the F-1 CubeSat.

[amsat-bb] Re: US Towers TMM-433HD for sale
Don't give up so easily... Massachusetts is one of the states that has codified PRB-1 into state law, so your fight should be easier than in a state where one has to go thru the federal courts. Does Holden have an antenna ordinance, and if so, what does it say? What steps have you taken so far, and what has been the outcome? Remember, the FCC & the courts have said that any "balancing test" is not allowed, arbitrary height limits do NOT meet the requirement of "reasonable accomodation" and "minimum practicable regulation", and under no circumstance can the municipality's actions have the effect of precluding amateur communication.

[amsat-bb] Re: perfect groundtrack contest
Hi Domenico, Thanks for the link. Most of the commercial GEO satellites in orbit are bent pipe translators, similar to the amateur linear transponders. Only in very few satellites in recent years have used on board processing and switching. The Intelsat IRIS payload, the INMARSAT F4 satellites supporting the BGAN system, and the ViaSat-1 satellite are some of the recent satellites that use various forms of on board switching. Most VSAT networks have the hub/control on the ground. All remote to remote connection are "double hop". Only remote to hub are single hop. There are some systems that are full mesh and allow single hop remote to remote communications. Commercial bent pipe transponders are typically 36 to 72 MHz. wide and are very linear. Each satellite typically divides their available 500 MHz of C or Ku bandwidth into transponders. The frequency can be 100% reused by using polarization diversity. They usually have fixed gain on the transponder controlled by uplink attenuators and downlink gain settings. It is up to the satellite operator to be sure that the total power of all the transponder users does not saturate the transponder SSPA. In almost all cases, this is a manual operation and if a single uplink site is transmitting too much power that user needs to be contacted and the offending station adjusted, really not much different than ham radio :) VSAT network operators can usually control the transmit power of their remote sites from the hub station. The current major GEO operators have an average of 80% capacity utilization. The going price for GEO capacity is in the range of $5,000 to $10,000 per Mhz. per month! . -Howie AB2S > From: domenico.i8...@tin.it > To: howied...@hotmail.com; w7...@comcast.net > CC: amsat-bb@amsat.org > Subject: Re: [amsat-bb] Re: perfect groundtrack contest > Date: Sat, 16 Jun 2012 01:02:57 +0200 > > Hi Hovie,AB2S > > You are correct but there is another reason that make very difficult to > use a commercial satellites for amateur communications. > > The Amateur Satellites and our ground stations are FDMA i.e Frequency > Division Multiple Access in wich the satellite passband is shared at the > same Time by all ground users depending on the frequency that they > chouses for the uplink and downlink. > > On the other side the Commercial Satellites are mostly TDMA i.e. Time > Division Multiple Access in wich a master Ground Stations send to the > satellite transponder the sincronization pulses to switch the onboard > multiplexer at very high speed and specific Time between all client ground > stations as explained in the following web page. > > http://www.satsig.net/vsat-equipment/tdma-explanation.htm > > In simple word the TDMA often called "switcher" operate as a citizen > Telephone Central Station that is not on earth but on board of the > satellite. > > 73" de > > i8CVS Domenico > > - Original Message - > From: "Howie DeFelice" > To: > Cc: > Sent: Friday, June 15, 2012 11:31 PM > Subject: [amsat-bb] Re: perfect groundtrack contest > > > > Unfortunately the hardware on board isn't programmable.
