[amsat-bb] W1AW/8 Ohio Satellite Operation
K8YSE will be operating as W1AW/8 beginning at 0001z 20 August 2014 on SO-50 as well as the linear birds. There was no satellite operation during the previous Ohio week in the first half of 2014. This will be the last chance to work this special event station in Ohio. I will operate on as many passes as my schedule permits. This will include FO-29 and AO-7B passes that cover Europe. Hope to work you. 73, John K8YSE ___ Sent via AMSAT-BB@amsat.org. AMSAT-NA makes this open forum available to all interested persons worldwide without requiring membership.

[amsat-bb] Grid Map Updates - CQ Europe/South America
Thanks to the following operators who sent updates and/or provided data for a new gridmap on my satellite website. W0DHB N8HM KB1PVH WA7ETH AC0RA W5PFG WD9EWK KO4MA PD4KH F6GLJ These maps show that there continues to be activity on the birds despite there being fewer to work through. I'm especially happy that we now have two gridmaps from Europe. Grid maps from European operators are always welcome. We could use some from Op's in South America as well. If you are looking for a rare grid to operate from, these maps will help you make a selection. It can be fun to operate on the other end of a pileup. Please continue to update your maps. If you haven't created a map yet please consider doing so. If you want me to create it for you just send two .txt files, one with your confirmed grids and one with the grids you have WORKED BUT NOT CONFIRMED, one 4 character grid per line. No amount of grids worked is too small. Every grid list started with the first grid confirmed! Website: http://www.papays.com/sat 73, John K8YSE ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] SO-50 QSO's
I heard lots of new calls on SO-50 today and I really wanted to give them a shout back and say welcome. Unfortunately, that's about all I heard was a bunch of folks throwing their call sign out. Is there some transmit only mode that I'm not aware of? ;-) On a more serious note, try to hear the downlink first before transmitting. It reduces QRM and greatly increases your chances of making a QSO! Thanks and 73, John W9EN ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] satellite grid map reqeust
Several years ago I started posting grid maps on my website so that grid chasers and grid expeditioners could get an idea of what was needed by active satellite operators. However, some of these maps have not been updated in quite a while. And there are many new grid chasers that have not submitted their maps for posting. If you have a map that is currently posted and has not been updated recently please send me an updated map(s) or just send me a text file of the grids you have confirmed, one 4 character grid square per line And another text file of grids you have worked but are not yet confirmed using the same format of one grid per line. I will generate the maps from these files and you can download and print the resulting map that will be posted. If you have never submitted a map, please consider doing so. Knowing who has what is very helpful to potential grid expeditioners and it is a nice way to keep track of what you need and where that grid is located with respect to grids you already have. It's a lot easier for someone in a grid adjacent to one you need to go there compared to someone who might live hundreds of miles away doing the same. If you send me your grid lists as specified above, I will generate the maps for you. Here's a list maps on my website and the date they were updated: AA4QE 5/11/2012 AC0RA 8/26/2013 CO6CBF 11/22/2011 K6YK 4/26/2011 KB1PVH UNKNOWN KB1RVT 9/6/2013 KB9RID 1/8/2011 KC0YBM 12/31/2011 KD8CAO 10/8/2011 KD8KSN 8/2/2011 KI6YAA 11/30/2010 KK5DO 4/21/2012 KO4MA 10/28/2013 N5AFV 2/25/2012 VA3OR 3/22/2012 W5PFG 9/16/2012 WA4NVM 2/27/2012 WD9EWK 3/4/2012 Info on how to make the maps is on the grid map page: http://www.papays.com/sat/gridmaps/gridmaps.html 73, John K8YSE ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] AO-7 CW Telemetry
It is very rare to hear clear CW from the AO-7B telemetry beacon around 145.972. Most of the time there is no beacon at all. Sometimes there is jibberish. Usually the signal is very weak. With AO-7 going through eclipse on every orbit, the satellite can come out of eclipse in different modes/ options. Recently there have been times where the beacon has transmitted clear CW over North America, something I have not heard over the years. According to the DK3WN website, there was some cw telemetry back in 2002 when the satellite was discovered to be working again. And there was some discussion about what is valid data based on the last 3 digits sent in the 24 group block of data. If the value is 649, 650, or 651, the data is likely valid. I first heard the image of the cw signal around 958. It was so loud I thought it was a valid user at first. But since the cw was all numbers I tuned up to the beacon frequency and there the signal was louder than anything I have ever heard on AO-7. It took a while for me to get the recorder running but I managed to capture some data. After playing it back I found that there was only one block of data where the last group was valid, a 649. Other later transmissions were loud but the data was much different and the last group was not correct. I couldn't locate a telemetry calculator at first so I decided to build one on Excel using the formulae provided by DK3WN. The data follows: AO-7B Telemetry 24July2014 2318UTC POS ParameterRange Raw Real 1A Total Solar Array Current 0-3000ma 171 2094.5ma 1B +X Solar Panel Current 0-2000ma 193 110ma 1C -X Solar Panel Current 0-2000ma 157 830ma 1D +Y Solar Panel Current 0-2000ma 108 1810ma 2A -Y Solar Panel Current 0-2000ma 286 250ma 2B RF Power Out 70/2 0-8watts 204 7.3728W 2C 24 Hour Clock Time 0-1440min 201 15.16min 2D Batt Ch/Discharge Current-2000/+2000 207 -1720ma 3A Batt Voltage 6.5-16.4 361 12.7V 3B Half Batt Voltage 0-10v 397 9.7V 3C Batt Charge Reg #1 0-15v 340 6V 3D Batt Temperature -30 to +50C 300 95.8C 4A Baseplate Temperature-30 to +50C 446 27.72C 4B PA Temperature 2/10 -30 to +50C 401 94.32C 4C +X Face Temperature -30 to +50C 430 51.4C 4D +Z Face Temperature -30 to +50C 498 -49.24C 5A PA Temp 70/2 -30 to +50C 545 29.2C 5B PA Emitter Current 2/100-1167ma 502 92.84MA 5C Module Temp 70/2 -30 to +50C 543 32.16C 5D Inst.

Some sensors might not be working properly since some values are out of range. However, the solar panel numbers might be somewhat correct. I wouldn't doubt it if the transmitter was putting out 7 watts at the time. Perhaps there are those who are familiar with the AO-7 telemetry that can make some sense out of the data. Unfortunately we don't have multiple blocks of good data to compare readings. Maybe some have recorded recent CW data and can find some good blocks that can be shared here. The data was copied on my Arizona remote and Skype was being used to listen. But I am fairly confident that the cw copied is correct. 73, John K8YSE ___ Sent via AMSAT-BB@amsat.org.

Soundcard interfaces to existing voice radios were a good start, but it's time to move past them. I've designed several modulation and coding schemes to fit existing radios, and their inherently limited bandwidth is a major pain. For ARISSat-1 I agreed to cram everything through a SSB filter, and I'm not doing that again. Not only does the narrow bandwidth often limit the data rate to much less than what the link budget could actually support, but it enormously aggravates the Doppler problem. It doesn't help that there are no industry-wide standards for SSB phase response or computer tuning, or that every time you retune one (which is often) there is a poorly characterized phase jump. Doppler is much easier to handle at high data rates because it's the ratio of the symbol rate to the Doppler that matters, not the absolute amount of Doppler. Now that we have a variety of pure digital radio front ends to choose from, it's time to set aside the voice radio + soundcard model. Not only do the SDRs support wider bandwidths but they tend to be considerably smaller, lighter and easier to work with in software. Some, like the Funcube dongle, are even considerably cheaper than conventional radios. --Phil ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

Re: [amsat-bb] going digital
Is there some reason why a digital signal cannot be passed thru an analog/linear transponder? What goes in is what comes out. It seems the lack of transponder bandwidth limits the digital signal experimenter... Maybe that is why commercial transponders on satellites are linear.

You will have changed the Icom address of one of the radios to allow control of both radios.. If the program starts - for example - with FO-29 choose the address of the radio at the 70cm antenna (downlink) as the first address value in the Radio 1 section of menu Radio Setup. and the address of the radio at the 2m antenna (uplink) as the 2nd address value. Uncheck the option Satellite mode and check the option Autotmatic Rx/Tx change. Withh FO-29 (v/u) the program will then steer the radio at the 70cm antenna as RX and the other at the 2m antenna as TX with FO-29. You can tune the VFO dial of the RX around the passband and the TX will follow. When you switch to VO-52 (u/v) the program will exchange the roles of the radios as RX and TX. You can tune the dial of the radio at the 2m antenna and the other will follow. 73s, Erich, DK1TB - Original Message - From: Ronald G.

[amsat-bb] Re: AMSAT-DL and Bochum Observatory receive signal from retired NASA spacecraft
Outstanding achievement! John - AG9D On Sun, Mar 9, 2014 at 8:17 AM, Peter Guelzow peter.guel...@kourou.dewrote: see also: http://www.amsat-dl.org/index.php/news-mainmenu-97/199-ice-satellite-received-in-bochum - AMSAT-DL and Bochum Observatory receive signal from retired NASA spacecraft On March 1st and 2nd, 2014 radio amateurs were able to detect the beacon signal from the retired NASA deep space probe ICE (International Cometary Explorer) at the Bochum Observatory (Germany). After some changes to the ground equipment and aligning the receive antenna to the predicted position in the sky, the beacon signal could positively be identified due to its frequency, the position in the sky and the frequency shift due to the radial velocity (Doppler shift). For this detection the 20m radio telescope from the Bochum Observatory was used. In 2003, AMSAT-DL converted this former industrial monument into a fully functional groundstation for deep space probes. Since 2009 the facility is being used by volunteers almost full time as ground receive station for data from the STEREO mission with its two spaceprobes monitoring the sun from different viewing angles. The International Sun-Earth Explorer 3 (ISEE-3) was launched in 1978 and became the first spacecraft to orbit the Earth-Sun L1 Lagrange point, measuring the interaction between the Earth's magnetic field and the Sun. It was the first spacecraft to detect the stream of particles (solar wind) approaching Earth. In 1982, the spacecraft was renamed the International Cometary Explorer (ICE) and diverted to the Moon, where its gravitational pull placed ICE on a heliocentric orbit. In 1985, the comet Giacobini-Zinner was visited (the first time a comet had been encountered by a spacecraft), followed by observation of Halley's Comet in 1986. While the instrumentation on board was still functional and fuel for more trajectory maneuvers was available, support for the ICE mission was terminated in 1997, though the spacecraft transmitter was left on. It was last detected by the NASA Deep Space Network in 2008. Its orbit however results in the spacecraft returning to Earth-Moon space in August of 2014. A small propulsive maneuver and lunar flyby could allow ICE to be directed into an Earth-Sun L1 halo orbit and perhaps resume a science mission, depending on instrument health. However in February 2014 a NASA study determined that the required resources to contact the spacecraft were not available anymore and due to budgetary constraints no further contact attempts were planned. In light of the recent observations and the available facilities in Bochum, additional studies about the economic feasibility to add a suitable uplink are being done. We would like to thank Jeremy Bauman from KinetX Aerospace (Tempe AZ, USA) for providing the ICE trajectory solution which was essential in finding the spacecraft and Jon D. Giorgini from the Jet Propulsion Laboratory (Pasadena CA, USA) for his support. About AMSAT-DL: AMSAT-DL (short for AMSAT-Germany) is an organization consisting of engineers, scientists, students, radio amateur operators and space enthusiasts. They design, develop, build, operate and use satellites in their spare time. In addition to ca. 600 members of AMSAT-DL other national AMSAT organizations count in total about 6000 members. AMSAT-DL is one of the few space organizations which lead satellite projects from the drawing board through design stage and construction into the operative service. AMSAT-DL projects strictly follow the open-source principle so technologies and procedures can be used by third parties. This includes also lessons learned and scientific results obtained during the satellite's operation. About the Bochum Observatory: The Bochum Observatory is a recognized and sponsored higher-education institution of the state Nordrhein-Westfalen (Germany) and is also funded by the 'Landeszentrale für politische Bildung NRW'. Next to optical sky surveys the focus of the current work is the recording of earth monitoring data from satellites. The main task is the scientific analysis and the public presentation of this data to understand the function of the 'earth system' and to characterize the effects and risks of human actions in the context of globalization. contact AMSAT-DL: Dr. Achim Vollhardt, icet...@amsat-dl.org contact Sternwarte Bochum: Thilo Elsner, i...@iuz-bochum.de mailto:i...@iuz-bochum.de, +49 177 50 70 797 --- ___ Sent via AMSAT-BB@amsat.org.

Preliminary keps are based on the trajectory when each is released? Ø Otherwise if they were released all at once, how would NORAD know which is which? Doesn’t much matter when they are released, they still are all in the same orbit more or less for quite a while. Even if the springs release them at 1/2 meter per second, they are all going at 7000 meters per second so it takes days for them to separate very much. Let’s see, at ½ meter per second separation, then they are 100’ apart after the first minute, 1 mile after the first hour. And not until they are a few miles apart can NORAD distinguish them enough to start getting good tracks on them. By then it is impossible to know which is which. Hence the guessing game until each owner decides which object best fits his downlink experience. Continuing on, they will be 24 miles apart after the first day where they will be about 5 seconds apart when tracked from the ground. After a week, then maybe 175 miles and ½ minute apart. After a month, maybe 750 miles and 2 minutes apart. After a year, maybe 9000 miles and 30 minutes apart. And finally, after about a year and a half, they will be half an orbit or about 45 minutes apart, beyond which, they start getting closer again… Something like that unless I screwed up… Bob ___ Sent via AMSAT-BB@amsat.org.

Years ago when a building was being built near the phone company building where I worked, the microwave signals would fade for no apparent reason. As the building, a block away, started to appear above the nearer buildings, we saw the crane used to raise material for the construction rising up in height, also. It turns out the crane cab was at the 250 height of our tower antenna. Whenever the cab swung into position to put it's load on the new building, we lost signals to/from our next relay tower, a major route node. Using a bit of hype, we told the crane operator that he would become sterile if he kept getting in the beam between towers. They moved the crane to another location. Both parties were happy.

I was glad to receive it. The problem is apples and oranges. Yes, they got ”37% efficiency, similar to the most expensive solar cells”, but the difference is that solar energy imparts about 100 watts of energy per square foot on a solar panel – remember, ONE HUNDRED WATTS/sqft. The amount of energy from a Cell tower onto a small antenna 1 mile away from the cell tower (typical) is only 0.0004 Watts. So there is about a one hundred trillionth of the practicality. Or another way to look at it. If you could hold their RF energy collecting antenna 1 inch from the cell phone tower (not one mile), to get more power, then the most power he could get would be only 3 watts. Still nothing close to what the sun provides. Plus, he would be absorbing all the power from the cell phone tower making it useless, plus the energy is not free. SO to get the same power as a palm sized solar panel, his RF capture antenna would have to be ONE INCH away from THIRTY cell phone towers. And, to generate that same 100 watts worth of RF energy, it takes about 300 watts of electrical power. (1 inch away) All to deliver about 1 Watt of power compared to the Sun which is free. Thanks.

The economic realities of this day and time make the possibility of a launch extremely remote and I don't see that changing in the near future. I can't understand why AMSAT continues to string people along with promises of maybe someday if you donate. Why can't they just be upfront about it and tell people, Hey it aint going to happen. There is absolutely nothing wrong with the new direction AMSAT has taken in pursuing cubesat technology and launches, I applaud them for it but the continued lip service to the we want an HEO crowd gets old.

[amsat-bb] Re: so long
Stefan, I second the comments . I brace myself every time I go to a hamfest to represent AMSAT. I would say I spend 75% of my time getting told that we are a bunch of morons and how the person complaining used to be a member but will never join again because we don't have a HEO bird. I spend time, politely too, with them explaining the world has changed in terms of launch cost and ask them if they have any ideas on how we can raise the money, that usually sends them on their way. I came to a great revelation this year looking back on my time as a club president, secretary and one of the 10% that actually does something other than complain and came to the conclusion that 75% of the rank and file hams want to open a box, sit in a chair, plug it in and yak in a microphone and complain. The other 25% are involved in experimentation, construction, education and pushing the service forward. The last time I checked, moaning and complaining to another ham who does nothing but complain doesn't get anything done. I should think that if there was anyone reading this mail service that had $10M to spare, they would have bought the launch by now. But go ahead and keep crying to the same group, maybe there's a recent lottery winner here.

We can have the best of BOTH FM and Linear!

We have that now in PSK31. Up to 30 channels in a single audio channel. So the ideal AMSAT transponder is a linear receiver (on 28.120 MHz) and an FM downlink of that single channel on UHF. This has the advantage of 30 individual linear uplinks to share amongst everyone, and the advantage of FM downlink so that everyone gets the same waterfall without added Doppler. It's a win/win. And it is FULL duplex so that everyone can transmit simultaneously and everyone can receive everyone simultaneously. What more fun can that be!!!

[amsat-bb] The USA Lower 48 Worked all 488 Grids non-Award
in 2013. Eight of those final 9 grids were handed out by Tom KA6SIP. He heard about the need and decided to make a grid expedition to put them on the air. He did 7 of them in one trip. Then Bob W7LRD went to the beach in CN77, operating away from home for the first time. That left CN72. Tom just got back from Hawaii and quickly made plans to camp out in CN72 and gave me the final grid on AO-7B, 20 August 2013 at 2332z. Then he put CN71 on the air on 22-23August, also a very rare grid square but one that I already had. Many others worked him there. There is no award for working all 488 grids on satellites as there is for six meters (FFMA). The ARRL awards committee has looked at it and will implement it if someone on the Board of Directors brings it up for a vote and it passes. Hopefully that will happen soon. Having that type of award gives everyone something to work for. It promotes grid expeditions and interest in working through the satellites. If we all contact our ARRL Director, it might just happen. There may be others who have already worked all 488 grids on satellites. K6YK might be one of them. I know there are several others who are getting close. It is not any easy thing to accomplish even if you operate every day. It is something you can work towards over the years. I want to thank everyone that made satellite contacts with me that ultimately led to working all 488. Many went out of their way to put on a grid. Over half of the grids worked were from grid expeditions! If you haven't experienced operating away from home, please consider it. With new operators showing up on the birds every day, there is always a need for an uncommon grid. And you will have a lot of fun doing it!

Now is your chance to work this grid and state. Mike was able to work down pretty low. This is a great opportunity. He was worked on FO-29. 73, John K8YSE ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Sub orbital launch from Wallops Island Virgina
A Sub orbital launch from Wallops Island Virgina will carry a payload built by students from Eastern Shore Community College as a RockSat-c project. I am posting to this group in hopes that some of you mid-Atlantic hams with high gain 2 meter antennas and possibly elevation control (depending on where you are- approx 70 miles elevation at apogee) will give a listen for it. Due to antenna constraints it will have a very low eirp. It will be transmitting standard aprs packets on 144.390 Look for kn4ge-12 or kk4pgr -12 as the profile changes. Launch is scheduled for 5 am EST on June 20th. Keep abreast of any delays or follow the launch at: https://www.facebook.com/NASAWFF?fref=ts Also, you can watch the launch live from Ustream when the time comes. http://www.ustream.tv/channel/nasa-tv-wallops Any reception reports are invited, even partially decoded packets at thomas.c.ri...@nasa.gov Of interest to many hobbyist, it will carry the first Raspberry Pi into space and also a nooelec SDR dongle that may possibly also be a first. I apologize in advance for any flooding of aprs that it causes but promise you it is a very fast flight. The profile change above 15k is intended to minimize potential for flooding.

[amsat-bb] WINAOS error message
WINAOS was working earlier on one PC (V. 4.0) but giving an error message on the other (V. 12.8). Now I get error messages on both PC's with both versions: V 4.0 - Listenindex uberschreitet das Maximum (0) V 12.8 - Listenindex uberschreitet das Maximum (-1) With these errors, I can no longer print out a list of satellites for a desired time period. Any help would be appreciated. John Kopala N7JK jkop...@gmail.com ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] Re: AMSAT needs volunteers ???
If AMSAT asks for volunteers its usually for newsletters, booth duty or web site maintenance. The AMSAT BoD raises money, provides it to groups doing development of amateur satellites and provides general services like this mailing list. In my experience, satellites are developed by dedicated teams that will ask for volunteers for specific tasks. For example, I was a volunteer for Eagle U-band receiver development. AMSAT might have passed on a name and the position had already been filled. 73, John KD6OZH - Original Message - From: Tom Lubbers K8TL k...@earthlink.net To: AMSAT BB amsat-bb@amsat.org Sent: Friday, June 07, 2013 15:55 UTC Subject: [amsat-bb] AMSAT needs volunteers ??? Over the past half century I responded several times to AMSAT’s call for volunteers and never heard back from them. I was happy to hear from my son when he volunteered his software talents to AMSAT and told me that they had asked when would be a good time to contact him. His job title is Software Engineer with over 30 years experience, a number of published articles and winner of a number of design contests. He is also comfortable with hardware and firmware. If I mention a piece of hardware or software that I wish was a available in my ham shack it is usually available the next time he visits. Oh by the way I see AMSAT is still looking for a software guy, they never followed up on their request of when they could contact him. They sure blew an opportunity there.

Currently, the only way that AMSAT-NA seems to be able to work with non-US citizens is via NASA which can more easily obtain the required approvals. 73, John KD6OZH - Original Message - From: Jaime Robles ja...@robles.es To: amsat-bb@amsat.org Sent: Friday, June 07, 2013 18:37 UTC Subject: [amsat-bb] Re: AMSAT needs volunteers ??? I answered last year to a call and I got an answer from AMSAT ... but it was negative due to the ITAR regulations and my Spanish nationality :-) Maybe if the US relax ITAR for hamradio satellites we (non-US hams) can help in future projects. :-) Just my 2 cents :-) Jaime, EA4TV El 07/06/2013 19:43, John Stephensen kd6...@comcast.net escribió: ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Re: Help in Hearing ISS
Les, Everyone has given good information. Let me add a couple of other suggestions specifically about ISS. We are using the Erickson radio ( basically an HT) in the Columbus Module. This is due to a fault with the Kenwood D-700. Maximum output on the Erickson is 5 watts. The radio is also used for ARISS school contacts in FM voice. The crew instructions for each contact give instructions to reset from voice to packet after each school contact. However there are activities aboard which require the ham station to be powered down from time to time so there are times it may not be active. We are finding with the reduced output power of the Erickson and the placement of the antennas on ISS that results will vary with ascending versus descending passes as well as whether the station passes to the east or west of your location, which means your signal will be going through the superstructure or unobstructed to/from the antennas. For the voice contacts we've always recommended a pre-amp at the antenna, even more so now, but I'm not sure how packet has been effected if at all with the change in radios. Anyway, it sounds like you are having fun. Keep it up! 73, John - AG9D ARISS Operations Team On Mon, May 27, 2013 at 10:10 AM, Les Rayburn l...@highnoonfilm.com wrote: I ran a Google search this morning, and there is still no known cure for operator error. So I resort to searching for more medicine on the list until a cure can be found. Please give generously until a cure can be found. :-) Been on satellites for about five weeks now, and have managed to work a few contacts through SO-50, FO-29, AO-7, and VO-52. Have copied CW beacons from other birds including a few of the small Cubesats. The system seems to be working well. Some bugs had to be worked out along the way, including adjusting Doppler correction on SATPC32, fixing an audio distortion problem, and desense in Mode J. But despite my best efforts, I've yet to hear a single peep out of the International Space Station. Not just in voice modes, mind you, but I can't seem to find the digipeater signals, or anything else. I'm clearly doing something wrong. So, here are my questions: 1.) My IC-910H is controlled by SATPC32 in satellite mode. Simple enough. But when I make the ISS the active satellite it stays in V/U mode, and won't easily let me go into simplex mode to work the ISS voice circuits or FM repeater. Is there a fix for this? How do other IC-910H owners deal with this issue? 2.) What frequency should I be looking for the packet signals on? I don't have a TNC, but do have a Rigblaster USB Advantage sound card interface. I know it's possible to use this to monitor (and possibly transmit signals to the ISS) Is there a link to a web site explaining how to configure the software, etc. for beginners? 3.) How often is the ISS in FM repeater mode? Not often, I'm guessing. Anyone know why? 4.) Any other tips on working the ISS? It would be quite a thrill for me! Please pardon the newbie questions. This list is great, and I really appreciate the help. We now return you to your regularly scheduled programming for smart, capable operators, already in progress. -- -- 73, Les Rayburn, N1LF 121 Mayfair Park Maylene, AL 35114 EM63nf 6M VUCC #1712 AMSAT #38965 Grid Bandits #222 Southeastern VHF Society Central States VHF Society Life Member Six Club #2484 Active on 6 Meters thru 1296, 10GHz Light __**_ Sent via AMSAT-BB@amsat.org.
