[amsat-bb] Re: Subject: Was, Is there anyway to get a linear transponder on the ISS?
Notwithstanding the difficulties and complexities of getting something up to and installed on the ISS, why would we want to put an obsolete radio up there anyway? Seems to me that a TM-D710 would be a much better replacement for the D700. For one thing, it has a built in cooling fan which should take care of the cooling concerns. It's obviously not a linear transponder, but then most hams don't have the equipment to use one anyway while most of us have VHF and UHF FM equipment. Coupled with a laptop, it could be used for WL2K comms, APRS and straight up packet in addition to plain old voice comms. Jeff Moore -- KE7ACY On 6/2/2013 6:23 PM, K5VOU wrote: Thanks for all the input regarding the FM 'repeater' on the ISS. Further research into the issues has enlightened me on the machinations of getting things done on the ISS and the complicated processes of working with such varied national interests. It is obviously way above my pay grade and with these comments I sadly end the quest with a feeling of not going anywhere. The Kenwood TM-D700 portion of the Phase 2 Hardware system is apparently overheating. Possibly because of a lack of airflow over the heat sinks. Possibly because when it is made available, the duty cycle rises to near 100% and the unit consumes too much power from the ISS power budget. Since the other parts of the Phase 2 system are fulfilling the needs of the ISS and NASA agenda, there are no resources available to correct the problems with the TM-D700. Indeed, replacing it with a linear transponder of equal bandwidth and much reduced power consumption may be a much better solution but there do not appear to be any benefits to the ARISS program to drive the solution. There was a mention in the paper produced circa 2002-3 of a third phase of the ARISS hardware system to be mounted outside but no mention of such a program since then has been located. Should others want to pursue a program of getting a linear transponder mounted on the outside of the ISS, I wish you luck and refer you to the document; Amateur Radio on the International Space Station - Phase 2 Hardware System by Frank H.

I wouldn't recommend a J-pole for satellite work unless you expect to only work sats on the horizon. The J-Pole antenna has a low take-off angle and almost NO radiation overhead, an plain 1/4 wave ground plane antenna would work better for the sats. J-poles are great terrestrial communications antennas, not so much for working overhead satellite passes.

May 29, 2011 To All RADIO AMATEURS BID: $ANS-149.03 Cornell University Chip Satellite Team Invites Ham Radio Collaboration A group of Cornell University-developed, fingernail-sized satellites may travel to Saturn within the next decade, and as they flutter down through its atmosphere, they will collect data about chemistry, radia- tion and particle impacts. Three prototypes of these chip satellites, named Sprite, were mount- ed on the International Space Station during a recent spacewalk. The thin, 1-inch-square chips are mounted to the external Materials International Space Station Experiment (MISSE-8) pallet, exposing them to the harsh conditions of space to see how they hold up and transmit data. Zac Manchester at Cornell University explained that the chips transmit as beacons with 10 milliwatts of RF power at 902 MHz using MSK modu- lation (minimum-shift keying) with a chipping rate of 50 kbps. The Cornell team invites AMSAT satellite operators to collaborate with this experiment to determine conditions in which the low-power signal has been detected on the ground. The Cornell ground station consists of a 18 dBi yagi with a GNU Radio and USRP receiver (http://www.ettus.com/products). A significant challenge is that the MISSE-8 pallet the chips are on is mounted on the anti-nadir side of the space station, facing away from the earth. The team is hoping to be lucky to catch some kind of reflection off the ISS structure. Beyond being able to detect the signal on Earth, decoding the message requires signal processing. The chips all transmit on the same frequency, each with it's own PRN code. The Cornell team uses these codes to differentiate each one, as well as to provide signal proces- sing gain. At Cornell, data is being recorded and post-processed with a standard PC. To track these chip satellites just use the ISS keplerian elements because they are mounted on the space station. Mason Peck, Associate Professor Mechanical and Aerospace Engineering at Cornell University wrote, Receiving the full sequence of data per se is not of interest, but the mere reception of it (a single digital bit, for us), indicates successful transmission. If you would like to serve as one of the lucky few to try detecting this signal, please follow up with Zac Manchester (z...@cornell.edu). We definitely welcome the collaboration of HAM operators.

[amsat-bb] Re: Operating practice on (mostly) FM sats
Phonetics should already be in use for the sats (I use phonetics all the time regardless of mode and band). It's probably a hurry up and get it done thing - operators don't want to bother using phonetics because it takes too long. I maintain that having to repeat yourself multiple times defeats the concept of NOT using phonetics in the first place. Ultimately, phonetics should be used anytime there is a possibility that the signal won't be clearly heard or understood.

Why not just use phonetics to begin with and make it easier for everybody to work stations? Just an idea. Comments welcome. 73 Mike K5TRI ___ Sent via AMSAT-BB@amsat.org.

So, What is your modest proposal?? Jeff -- KE7ACY - Original Message - From: Thomas Doyle tomdoyle1...@gmail.com The bulletin board system AMSAT is using is well suited for information that is useful for only a relatively short time. If there is a trip to a rare grid location that information is of little use after the event takes place. IMHO what is missing is a way to share information that has relevance beyond a few days. When I became active again on the sats I asked a question on the board. I received an email telling me that that question has been asked several times before. It was helpful beyond belief. In the last few days someone posted a nice check list of things to do to try and get your SatPC32 station running. A bit later someone posted a correction that added a vital step that was missing in the first posting. Suppose a newbie subscribes to the board today - he has already looked at the articles from 1997-2004 in the new users section on the AMSAT website but needs a little current info. He posts a message on the board asking about getting his SatPC32 station working. Lets hope no one sends him a message telling him that that question has been asked before. I also hope no one sends him a message suggesting he uses the search funtion. That would be like the 4th grade teacher who responded to my question How do you spell pneumonia ? - by telling me to Look it up in the dictionary - I spent a lot of time looking for words that started with N before asking my folks when I got home. If they did search - what would they look for. What are the chances that they would find the initial post AND the correction post. I realize everything is perfect as it is but perhaps it would be nice to have something similar to the Yahoo Groups where subscribers can post files and pictures of things that would be of interest for more than a day or two. Take a look at the SDR-Radio or Softrock groups on Yahoo. There are files and pictures that have been very helpful to me. There was a recent posting here from someone asking for a current Doppler.SQF file. I sent him mine but it would have been better if there was a place to store it where anyone could access it. Some people have their stations working well but are not all that excited about spending a lot of time documenting it and posting it for a handful of people who might look at it before it disappears into the abyss of the message archive.

[amsat-bb] Re: KD8KSN/M a question
I could be wrong, but I suspect a couple of things: 1. The fact that your downlink antenna is always vertically polarized rather than steered to the polarization of the satellite. 2. The position of the antenna on your vehicle could also have a huge affect as well as the orientation of the vehicle to the satellite during the pass. Isn't the FT-350 full duplex capable? 73, Jeff Moore -- KE7ACY - Original Message - From: Zachary Beougher zack.kd8...@hotmail.com Hi All, Thanks for the QSO during my few mobile ops the past couple days – and for your patience. We had three small road trips planned for various reasons Wednesday-Friday, so it provided a great opportunity to try the mobile equipment out, find out what combinations work better than others, etc., etc., so I can perhaps get on the air a little more while mobile during vacations and such. I will be uploading all QSOs to LoTW within a day or so, and if anyone wants a card just email me the QSO details. I did have a question: One consistent issue I found while operating is that I could just barely hear a bird from AOS-TCA, but from TCA-LOS I could hear fine, even down to 10-5 degrees. I am not understanding why I can’t hear one side of the pass, but I can hear the other fine – almost full quieting with the preamp. I should also mention that I experienced this issue on AO27 and SO50, not AO51. I would thinnk it would be a polarization issue, but that still doesn’t make sense to me. My main setup consisted of: Uplink: TH-D7A (7w plugged into 12VDC), Comet CA-2x4SR mag for uplink. Downlink: FTM-350AR, ARR SP432VDG preamp on battery or 12v, Arrow duplexer (440 side hooked up which solved my desense issues so I could work full duplex), and a 19” quarter wave mag. I had posted here about a month or so ago wondering if intermod would be an issue using a preamp while mobile. I monitored about 7-8 passes over the past three days while mobile and intermod was never an issue. I did have a little bit of alternator whine on the FTM-350AR’s receive, but it was very minimal. That could be solved by running the cables directly to the battery. Since we were in the family vehicle I just used the cig lighter (I know that’s not a good idea, but it was only for a couple days). 73! Zack KD8KSN ___ Sent via AMSAT-BB@amsat.org.

See comments in line below: Jeff Moore -- KE7ACY - Original Message - From: Glen Zook gz...@yahoo.com I can assure you that in basically 52 years of working DX that geographical names definitely work better in the vast majority of situations than the ICAO phonetics. Yes, eventually, the ICAO phonetics will be understood. However, the station on the other end is generally going to work stations that are the easiest to recognize and that includes what phonetics are used. Therefore, how much time you spend in the pileup depends on how well the DX station understands your transmissions. As for me, I prefer not to spend a long time in a pileup! == If everybody is using the same phonetic alphabet, then there shouldn't be any problem understanding what one is saying. I give up! The same arguments that are made time after time on QRZ.com for using only the ICAO phonetics are being made here. Frankly, the ICAO phonetics do NOT work well, if at all, for certain letters when the other station does not have English as their first language, especially when QRM or QSB is present. == Don't you ever wonder why you keep seeing the same arguments?? The ITU phonetic alphabet works fine if it's used. I keep saying that ICAO phonetics are fine when English is the first language of the person or if the person who does not have English as their primary language has had formal training in the proper use of the ICAO phonetic alphabet. However, when the ICAO phonetic alphabet fails, then the operator needs to have an alternate phonetic alphabet available rather than continue to attempt to get the information across using the ICAO phonetics. == Training comes from use. What I don't understand is how you can advocate a phonetic alphabet that by your own admission isn't even documented legitemately anywhere let alone recognized or recommended. I am receiving numerous E-Mails from people who definitely agree that when working DX using geographical names usually works much better. But, those persons are hesitant to enter into this discussion. == Could it be that they understand the quicksand you're standing on? Basically, everyone is chasing their tail. That is, those who think that the ICAO phonetics are sacred and need to be used no matter what against those who believe that certain circumstances require using an alternative phonetic alphabet. Few persons are going to change their minds! == There's nothing sacred about the ITU phonetic alphabet. It's just the current Internationally recognized and recommended standard that should be used. Anything else just confuses people. One needs to look at the public safety arena where the ICAO phonetics are just not used. If the ICAO phonetics are so great then why is there an APCO phonetic alphabet? The basic answer is that public safety organizations have found that the ICAO phonetics just don't do a good job. Therefore, the APCO phonetic alphabet. == Public safety organizations use their own phonetic alphabet for the same reason they use their own numeric codes, to confuse the general public and make it harder for them to understand the info being passed. It has nothing to do with one being easier to understand than the other. I can assure you that this discussion will never end because those who insist that the ICAO phonetics must be used no matter what seldom realize that they are no panacea and that alternate phonetics do have a place in radio communications. == You're right! As long as people argue against the accepted, documented, recommended prevailing standard, the discussion will go on. Come up with a documented, better phonetic alphabet and get it internationally recognized and recommended and then this discussion will go away (or at least be changed to an argument between the old and new standard). As long as there is no official alternative (and I don't give a rip about how long the geographic non-documented non-standard has been used), the internationally recognized standard is what should be used. You can play your word games all day long on DX, but as soon as you start working emcomm - you'd better be using the accepted standard or you're putting people's lives at stake.

Jeff Moore -- KE7ACY - Original Message - From: Glen Zook gz...@yahoo.com Actually, the NATO phonetic alphabet was NOT developed by the military. It was developed by the International Civil Aviation Organization during the 1940s. It was adopted by NATO during the 1950s. Again, my position is that the ICAO phonetics usually work very well with those who speak English as their first language. It works fairly well with those persons who do not speak English as their primary language but who have been specifically trained in the use of ICAO phonetics. It generally works very well on radio links that do not have extensive QRM or QSB. However, when dealing with untrained individuals who do not speak English as their primary language and when QSB and/or QRM is present, geographical names work considerably better. The same arguments that are being presented herein are routinely posted in the discussions on QRZ.com concerning the proper phonetic alphabet. Frankly, the majority of people have made their decision and they are not going to change how they use the phonetic alphabets. Some use the ICAO phonetic alphabet no matter what and some people do adapt to the situation and use alternate phonetic alphabets of which the geographical name version is the most used of the alternate phonetic alphabets where amateur radio is concerned. When working DX through a pileup the vast majority of time stations who use geographic names are going to get through a lot faster than those who insist on using just the ICAO phonetic alphabet. This is contrary to the opinion of those who insist that the ICAO phonetic alphabet must be used. However, for those stations who routinely work DX the vast majority do use geographical names when working DX. Now when working stateside the vast majority of those operators do use the ICAO phonetic alphabet. I have heard these same arguments numerous times before concerning the ICAO phonetic alphabet versus geographical names. A relatively few persons who have insisted on the ICAO version do realize that the ICAO phonetics are not a universal savior where communications are concerned and do change their operating habits to fit the situation. But, those who insist that the ICAO version is the only correct phonetic alphabet generally are not convinced. Frankly, these discussions go on forever and no resolution ever happens. As such, those discussions are eventually shut down and things return to normal. As for me, I will continue to use the ICAO phonetic alphabet for stateside contacts and when the other station has English as their primary language. However, I don't like to spend a lot of time in pileups when working DX stations and therefore I will continue to use geographical names and work the station generally along time before those who use ICAO phonetics get through. Now getting back to satellite communications: Generally, since the vast majority of stations worked by United States operators do have English as their primary language, I definitely agree that the ICAO phonetics should generally be used. For stations who do not speak English as their primary language then using geographical names is definitely a viable alternative.

Do any of the current or classic satellite HT's (FT-51R, IC-W32A, etc)
allow you to create a single channel with a FM bird rx/tx pair in full
duplex?
I.e. I turn one knob and get 435.310 145.875
{click} 435.300 145.880
{click} 435.290 145.885
I could do this with the 20 DUP channels on the Ft-100D.
Even though the IC-W32A has two knobs, it looks like (from the manual)
only one can be in memory mode at one time, so TX would be in VFO mode,
and the other would be in channel mode. Is this correct?
So for each change (AOS, MID, LOS), I have to turn both knobs
one click, correct? Even if I can have memories on both sides,
I still have to turn both knobs -- If so, why wouldn't I just use a
VX-170/VX-177 pair of HT's, and turn both knobs?
I can program my DJ-V5 to have the odd split (TX144/RX432)
single knob channels, but of course, it is not full duplex.

Horizontally polarized beams will not work very well for satellite use. For maximum utility, I'd get crossed yagis set up to switch between horizontal, vertical, and circular polarization. Use the circular polarity to work the sats, horizontal polarity to do weak signal work, and vertical polarity to pull in those weak repeater and FM simplex signals.

One concern that I have is that the horizontal antennas seem to have a somewhat limited frequency range, and I'm not sure of the impact. Also, is it prudent to go with separate azimuth and elevation rotators to allow for future expansion (6m etc...), although the separation required between booms is height prohibitive with 6m? Is anyone running a setup similar to this? Are you happy? Any thoughts, opinions etc... would be appreciated, Zach N4ERZ ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author.

[amsat-bb] Re: Logbook software?
I like the DXKeeper app that is part of the DX Lab Suite of apps. Others will likely have other suggestions. Jeff Moore -- KE7ACY CN94 - Original Message - From: Bryan Green kl7cn...@gmail.com What's the favorite logbook software for satellite work? I've asked a few prolific ops privately but am curious in public. It seems to me that the usual suspects for HF work are not adequate for the roving grid hoppers among us. The one thing it seems software could do nicely is automate the (now possible) LotW upload and reconciliation. I'm not much of a Linux desktop user, but I do use both Mac and Windows. Any recommendations? Thanks in advance, and obligatory apologies to the OTs for repeating a question. :) Bryan Green KL7CN Usually /W6 in CM98fn 408-836-7279 ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Re: KIT
Insulting people probably won't get you what you're looking for. I did a search of the QST archive and came up empty, so I doubt if there was an article (I could be mistaken). Most kits out there are for HF equipment usually QRP (low power), I don't personally know of a 2m/70cm kit of any kind. There are lots of homebrew projects but again they are mostly for HF. If you have more specific information, by all means post it here. I'd be interested. As for other forums, they are too numerous to list. Your best bet would be to go to Yahoo groups and do a search on applicable topics and/or equipment models. There are a lot of hams that still build stuff - mostly antennas, but other equipment as well. There just aren't very many kits out there anymore. If you run across a vhf/uhf kit of any kind, I'd be interested in learning more about it. Jeff Moore -- KE7ACY CN94 - Original Message - From: Kevin Deane summit...@live.com Is there another forum, because obviously everyone here just buys everything and maybe have forgotten what this hobby is all about! I know there is a kit out there for a receiver and or a SSB converter. 2-meter/70cm SSB receiver. I heard there was an article in QST so it must exist. I am young, enthusiastic, and have lots of time, any help would be great. :) Kevin KF7MYK ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

One thing you might want to consider is the online tracking sites like the AMSAT site and the N2YO site.

[amsat-bb] Re: Is it possible to work LEO sats (FM or SSB) withantennas in attic?
The first half dozen or so satellite qso's I did were done from inside the house using a handheld 70cm yagi. Uplink was done via an outside dual band groundplane on the roof. The receive was done with the yagi and by experimentation, I discovered that reception was much better outside than inside. Problem was it was TOO cold outside at the time. Given all that, your az/el setup with decent yagis (preferably x-yagis with circular polarity) and a preamp for 70cm downlink should be very workable unless you have metal roofing. 73, Jeff Moore -- KE7ACY CN94 - Original Message - From: David Mennerich david.n2...@gmail.com I have HOA rules that prevent me from putting antennas on the roof where I live. However, I can put antennas in the attic. I have an Az/El setup that I could mount up in the attic, but wanted to get some feedback from folks on any experience they've had working the LEO satellites with antennas in the attic.

Hi Loren, I would hazard a guess and say in one word -- NO! :-) The split between the satellites may be similar to what others are doing, but I seriously doubt if ANYONE is working the satellites to the level that you are. If you stopped at 1000 qso's, how many did you actually work?

[amsat-bb] Re: thd72a
Hi Bruce, You need to spend some time with the manuals (both the printed and cd-rom versions). This is an extremely complex radio system do not be fooled by it's size. Date/Time is set automatically when you turn on the internal GPS (page GPS-2 cd-rom). You have to set the time zone manually via menu 196. Page 33 of the printed manual tells you how to input text/data to the menu options. It's likely that most of the APRS defaults will work, but spend some time with the manuals and the APRS web-sites to figure out what options are needed/required in your particular area. Contacting a local APRS Elmer would be helpful as well. Have fun! 73, Jeff Moore -- KE7ACY CN94 - Original Message - From: Bruce kk...@arrl.net oh, boy, got a thd72a. however, this is my first kenwood radio and i got it to turn on and figured out how to put it on a local repeater. that works. next i thought i would give the aprs a try. i have never used aprs before. i put my callsign in. but have no idea what to do next. the manual isn't really any help as i don't know what values need to go into the aprs fields or where to program in the aprs frequency. which i don't have either. i may have bit off more than i can chew with all the features of this radio. also, how do you set the time/date. looks like there is a place for it at the bottom of the screen but can't figure out what to punch to get it to do something. 73...bruce ___ Sent via amsat...@amsat.org.

[amsat-bb] Re: Transit Satellites
Bob is loking for possible suggested uses of the satellites. I have a suggestion (I don't know if its workable or not): How about uploading the latest satellite keps and using the Transit sats to update the keps for people that are located in areas where they don't have ready access to the Internet like at sea or in places like the Yucatan or remote Africa. You could put a receiver on line with your computer and when the sat is in range download the latest keps. That would give you accurate pass predictions allowing you to work the ham sats or download weather info, etc. w/o needing the Internet to keep the keps up to date. What do you think?

[amsat-bb] Re: Circular Polarized Antennae
If you're going to post an ad, you should at least provide the proper contact info like web-site etc. so that we can take a look at your products - don't leave us hanging. Jeff Moore -- KE7ACY CN94 - Original Message - From: Spectrum International, Inc spectrum.ma.ultra...@rcn.com John, LA2QAA That was an interesting message you posted to the -bb this morning. It has many true observations; however there is one serious mistake, an unforgivable error. Quote: . particularly by the newcomers - who apparently, and mistakenly, think that high power is necessary. It's *NOT* . . . nor is an EME class aerial array necessary to work the LEO satellites. Ditto circular polarisation. FACT:polarisation is *ONLY* circular along the boresight of an aerial. Unquote. Your polarization statement is not 100% accurate. Unfortunately most antenna manufacturers, who supply/sell alleged circular polarized antennas do not state that their antennas are circular polarized ONLY along the boresight. They conveniently (?) do not mention that their alleged circular polarized antenna is only circular polarized on boresight, that it is linear polarized at 90 degrees off of boresight and is elliptical polarized of varying ratio at all angles in between! There is however one (and only one that I am aware of) antenna design that is circular polarized over its entire radiation pattern. I refer you to the Q_uadrifilar Helix Antenna_ described by Dr. C.C.Kilgus in IEEE Trans., Vol. AP-16, July 1968, pp. 499-500. Also Bricker, R.W. and Rickert, H.H., in RCA Engineer, Vol.20, No. 5, February/March 1975. There is an excellent review by Walter Maxwell, W2DU, at http://www.IAG.net/~w2du/quadfinal.pdf. When installed pointing to the zenith, the ideal, theoretical Quad Helix has 360 degree coverage in the azimuthal plane and 90 degree coverage in the elevation plane. It is circularly polarized over the entire upper hemisphere. There is no radiation in the lower hemi-sphere; the energy in the lower hemi-sphere of an isotropic radiator is uniformly distributed over the upper hemi-sphere. Hence the gain of an ideal Quad Helix is 3.01 dBi. However you can modify the elevation pattern to give more gain at the horizon and less gain overhead by adjustment of the overall length to diameter ratio. It is possible to adjust this ratio to give constant signal amplitude, at an earth based receiving station, from a satellite in a circular orbit where the range ratio (and hence signal path attenuation) between AOS and the zenith can be significant. This results in a little radiation below the horizon and also avoids the nasty mathematical boundary value problem at the horizon in the ideal case. Quadrifilar Helix antennas are used on many LEO satellites for VHF, UHF, L-band and S-band communication. One of their parameters of interest to satellite builders is that they do NOT require a ground plane provided they are at least a quarter wavelength above the satellite structure. Hence there is negligible critical location requirement and they do not occupy satellite surface area that is required for solar cells. The Quadrifilar Helix antenna is popular with earth based receiving stations for receiving the VHF image data signals from the NOAA weather satellites. Right-hand circular Quad Helix antennas for the 137MHz NOAA weather image signals and 137MHz left-hand circular Quad Helix antennas for receiving the ARGOS programme signals, are available from Spectrum International, Inc. Spectrum also supplies both right-hand and left-hand versions for the 2M and 70cm Amateur radio bands. May we suggest you sprinkle some Grow More fertilizer around the base of your chopped down satellite array every Sunday morning and offer a few words of wisdom while so doing. With a little help and the dregs of Saturday night's Black and Tan, your mini array might grow. Regards, Spectrum. ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author.

[amsat-bb] Re: Former NASA head on Downed Plane - update
I've heard that Reuters is reporting their survival and I certainly hope it's true, however, based on the press conference I just watched from Alaska, there hasn't been any official release of survivors names. Only that there were 4 survivors, 2 of whom are in serious condition - NO NAMES. Jeff -- KE7ACY CN94 - Original Message - From: David - KG4ZLB kg4...@gmail.com ORLANDO, Fla. (AP) - A former NASA spokesman says ex-NASA chief Sean O'Keefe survived the plane crash in Alaska that killed former Sen. Ted Stevens. Glenn Mahone says O'Keefe's teenage son, Kevin, was also among the four survivors. The plane crashed Monday night near a remote fishing village in Alaska, killing five. The former spokesman for the space agency says he has talked to O'Keefe's family. They told him that O'Keefe and his son had some broken bones and other injuries.

[amsat-bb] Re: Icom 910H vs Kenwood TS2000
The IC-910H is officially discontinued by Icom. It's being replaced by the IC-9100 which is a dc to light all-in-one box like the TS-2000. The IC-9100 isn't yet available in the US - still awaiting FCC approval. According to Icom, the IC-9100 is a combination of the 746Pro (also discontinued) and the 910H. No pricing yet either, but I wouldn't be surprised if it comes out substantially more expensive that the TS-2000. Icom plans to debut the IC-9100 at next years Dayton Hamvention. If it's significantly more expensive than the TS-2000, I'll buy the Kenwood rig. Jeff Moore -- KE7ACY - Original Message - From: Tom k...@cox.net I plan to purchase a new home transceiver in the next few months and I've narrowed my choices between a 910H and a TS2000. Thinking only of satellite operation (ignoring the HF capability of the TS2000), is there a general preference in the Amsat community of one over the other? Reasons? Thanks for your opinions.

[amsat-bb] Re: Icom 9100 release date?
According to IcomAmerica, the IC-9100 is slated for release at the Dayton Hamvention next year. When it actually becomes available on the US market is up to the FCC. It is the replacement for the 746 Pro and 910H, hopefully it won't cost as much as both of them together. Jeff Moore KE7ACY CN94 - Original Message - From: John Geiger aa...@yahoo.com Subject: [amsat-bb] Icom 9100 release date? I see that both the Icom 746PRO and the Icom 910H have been discontinued, and I am assuming that the Icom 9100 is the replacement for both of them.
