[amsat-bb] AO27 status
Heard AO27 a couple of times. Both yesterday and today. Today I heard it around 18:10 UTC. The telemetry was good and strong. Hopefully they can get this old girl working again as well. It was a nice FM satellite after the demise of AO51. Reid, W4UPD ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] Re: AO-10 and AO-16
On a side note. Do we know the 'physical' status of AO-40? Is it still orbiting the earth? I don't believe I heard anything about it re-entering. I do remember a conversation here on the BB some time ago about making an attempt to command AO-40 again to see if it will respond. However, the command team stated they were reluctant to do so in the event it might cause further harm to an already bad situation. My comment would be that if this were the case what can we lose since we've gone this long without having its access. I think that if there is even a 1 percent chance of commanding it, it should be attempted since we've nothing to lose. Again, I may be in left field and missed something here, but I feel if there is a chance, it should be given a shot. If things go wrong, we're not any worse off then we have been without it being operational so long. Then again the command team may have already made an attempt and my comments are mute.

It was a low pass, and I hope to check again in the next few weeks. If you'll remember, the problem with keeping the satellite ON is temperature related. If it gets lots of sun (little eclipse), it will be warm enough to remain on. Otherwise, it won't...and the orbit is such that it doesn't get enough sun--and it probably won't for another 10 years or so. But I check periodically. About every week or two Drew KO4MA and I try to turn AO-51 back on. My latest try was last Saturday. Nothing heard. IO-26 is still up there, and still humming; it needs to be turned on from time to time, so I do that. But we haven't figured out how to run it in voice like we did with AO-16; it doesn't appear possible. Don't know about AO-10; I haven't listened for a while.

Kind of cool and sounds like a lot of fun. I decided to try Yuri's movements on a marine traffic URL. The chart can be be found at: http://marinetraffic.com/ais/ You can put in the name of the ship. In this case just the Barnacle works. At this email writing, the chart shows him at: N46. 31', 01.62, W072, 12'53.89 or 46.5171, 072.2150 Of course by the time this email gets out he'll be a different location. This program is neat and I use ti to track passenger ships as well. Again, sounds like a really neat experience that most of us would envy.

He had gone through the Welland Canal which connects Lake Ontario to Lake Erie on the way to Thunder Bay and would come back through on his way out. The Welland Canal is very long, has 8 locks and takes the boat from a water elevation of 572' in Lake Erie to 246' in Lake Ontario. On the way in it took him about 8 hours to go through. My thought was to drive up there and watch him go through and hope we could get within shouting distance of one another. But where you do go to get close and how do you find your way around in unfamiliar territory? You may have heard VE3RCN on the birds, sometimes from different grids and sometimes on the warship Haida. Kevin is in the Royal Canadian Navy (hence the callsign) and makes his home in Welland! After some email exchanges and some research on Kevin's part he offered to host my time in the area. That took all of the stress out of the situation. He knew everything about the canal. Yuri sailed out of the Detroit River on Saturday night and into Lake Erie. I was able to contact him on 144.200 sideband where we chatted for almost an hour, much different than the quick grid square exchange on the birds. He estimated being at Lock 8 in the Welland Canal around 8am. After 4 hours of sleep and a quick shower I was on the road at 3:15am. After a few questions by Canadian Customs (they know what to ask to determine if you are telling the truth), I was in Canada. About 15 minutes out of Port Colborne, the entrance to the canal, Yuri called on 146.52 to say he was about 15 miles out. Fifteen miles later I was at Tim Horton's (the Canadian Starbucks equivalent) where I was to meet Kevin, VE3RCN/VA3OR. He arrived their shortly after me and we were off to the Lake Erie shore to catch a glimpse of the MV Barnacle. And there she was off in the distance. It was all coming together. The Lake was calm, the sun was shining, it was about 32 degrees but there was no wind. The fish were jumping. After the ship started moving closer to the channel we got into position to watch it come in. As it rounded the bend and we could see the bridge, Yuri spotted us immediately and was waving. He seemed as excited as we were. As he got closer we were able to shout back and forth. At Lock 8, the first lock, we were able to talk back and forth; we were very close. There are places on the canal where you can stand on the bank and put your hand on the ship going by. The clearance may only be six inches. After that we went to get some breakfast; then we lost track of where Yuri was. Kevin made a quick call to his xyl Donna, VE3WIZ, and she was able to relay his position so we could catch up with him again. We waited for him to pass over the highway at Thorold. The road actually goes under the canal! Next stop, Lock 7. We were waiting for Yuri at Lock 7 where the Canal Pilot changes. We were standing at the fence when things started to come together. The invitation to come on board was given and before I knew it I was ushered over the lock to the other side of the ship and boarded as the ship lowered to the dock level. A minute later I was on the bridge with Captain Yuri UT1FG. Finally I was able to meet a guy that I've been working on the satellites in hundreds of water grids since April 2009! At that point Kevin went back home to get Donna and they then followed us down the canal, waving and watching us at every highway crossing and vantage point. An experienced Canal Pilot takes command of the ship through the locks. He stands on the port or starboard side of the bridge so he can see the ship's hull with respect to the edge of the canal. There may be only inches to spare so it is a tedious effort. The Pilot calls out the commands (Starboard 20, Port 10, Slow Ahead etc) and the first officer carries out the orders. Yuri is usually with the Pilot and helps relay the commands etc. There is very little time for anything else except when you are actually stopped in the lock. It's one thing to see the ship going through the locks from land but quite another to experience the change of level from inside the lock itself. It truly was an experience of a lifetime. Yuri took me to his cabin one level below the bridge. His quarters are quite

[amsat-bb] Re: Mirage preamps
I agree on the possibility of some line loss to the unit. The longer the coax run the more problems you may have with it properly switching. I found this to be especially true of the early models of the Mirage mast mounted preamps. Even the power T can be a problem if the wire run is long. Presently, I am using my unit on the IC-910 without any problems, but the coax run is less than 50' of 9913. I would recommend holding onto the KP-2 for awhile. If the rig is border lined with the output voltage being around 12 volts instead of around 13.8 volts, there could be enough loss (even .5 volts) can cause erratic operation. Using the KP-2 allows you to use a separate voltage allowing sufficient amount to the preamp.

I have had some success with vertical monobanders on all of the birds including VO-52 and A0-7. I use a Ringo Ranger II on two meters and a 1/4 wave homebrew two meter groundplane for 70cm, which makes it 3 waves long for 70cm. The main disadvantage I run into is that two different antennas located at different locations on the house here cause dissimilar tracking of the birds. Remember, a vertical antenna with gain will cause your angle of radiation to be lower than a simple 1/4 wave for that particular frequency. I find that with the Ringo my best angle is about 15 - 50 degrees. The 1/4 wave 2 meter used on 70 cm is a bit better. It is difficult to work AO-7 with this arrangement but is doable. Some day I'll get my arrays back in the air (down since the storms of '04').

The schematic locates the capacitors in the rotor for elevation and in the control box for azimuth. This unit uses relays to perform the actual switching. So check the following: 1. Disconnect wires 4, 5, and 6 to the elevation rotor. If you don't disconnect the wires, you will get a reading on both pins 4 and 5 measured from pin 6 due to the run capacitor. 2. Use a voltmeter to check for AC voltage between pin 6 and Pin 5 when you press the UP button. 3. Check for AC voltage between pin 6 and pin 4 when you press the down button. 4. I don't know the exact voltage but would guess something around 25 to 30 volts AC. 5. If these work correctly, the problem could be the limit switch, the run capacitor, or the motor, all located in the rotor housing. 6. If either voltage is not present the problem is in the control box and could be either the relay or the relay driver transistor. That should help pin things down quickly.

As I am using the Trackbox, and i did not have under my eyes the control box, I heard the Trackbox passing from ISS to AO-51. I gave an eye to the control box and saw it was stuck at 35 degrees and it did not go down to the 0 degrees to start the AOS. I have pulled out the connector which connects the control box to the Track box and tried manually To bring down the antennas. I've tried to press the DOWN switch, but they did not move from that position. I've tried to press the UP switch and noticed that the antennas moves going up. Then i have tried also with the RIGHT and LEFT switches of the Azimuth and noticed also that the antennas moves in both sides. At the end i can say that the antenna moves in all the positions except for down. Please anybody can tell me what is happened? As the antennas are now stuck at 45 degrees i am afraid that the wind can cause problems. I Hope in an help. Any help will be really appreciated.

[amsat-bb] SATPC, IC910 Doppler
I may missing something obvious, but when tuning the IC-910 on FM satellites I noticed that under normal SQF files for AO-51, as an example, both uplink and downlink do doppler adjustment. In the case of FM or AO-51 in this case, I want the uplink to stay the same and only the downlink to doppler adjust. I also find that if I select the mode of downlink only, when the tracking and doppler starts the mode changes to downlink uplink and then blanks out so you can no longer change it. I have found a way to prevent this but it means manually setting the uplink frequency. If I edit DOPPLER.SQF to have downlink only and an upplink of 0, it prevents the uplink from adjusting. However, I had to manually set the uplink to the frequency I wanted. This works, but I feel I'm missing something simple. Also, I've gotten use to using the IC-910 for 2-mtr band A and 70cm band B and only band A transmits. Unable to do this in SATPC. However, no big deal as the Satellite mode all works well, except the doppler adjustment of the uplink. Anyone with an idea what I'm missing here? This is the first chance to really use SATPC as I have been normally doing manual tracking and the AFC on the downlink which works quite well on the IC-910.

Since the changes made to AO-51 the other day, it appears I am having more difficulty in copying the bird than others on this list server.

Although I have owned Kenwood equipment (and still have the TS711/811 pair) I purchased an Icom IC-910 and have been very happy with it. I have a few friends with the TS2000 and although it is a nice rig, I found the IC-910 to be more sensitive to weak signals related to satellites and have at times received the signals without using my preamp. The TS2000 also have some birdies in the satellite frequencies that can be annoying and this problem has not nor do they plan on fixing. If you do not have a rig yet and wish a unit that covers HF/VHF/UHF than this may be the unit. Frankly, I don't like having all my eggs in one basket in the event the rig fails, you lose it all. You can get other rigs cheaper that cover HF/VHF/UHF that are not satellite rigs at affordable prices and still get the Icom IC-910 which is what I did. Also, if you want to add 1.2Ghz it is less than a 5 minute project on the IC-910. The TS2000 is a bit more time consuming and difficult. Just my two cents.

[amsat-bb] Re: Icom 910H vs Kenwood TS2000
Sorry to hear about your power output problems on your IC-910. I do not have that problem. It requires an SWR of over 1.5:1 before I start seeing it degrade in output power. I have almost 100 watts (stays around 98 watts output) for the entire 2 meter band until the swr goes above 1.5:1. 70 cm is the same. I have at least 75 watts out on 70 cm even running it into a 2 meter ground plane or MFJ discone. However, the 2 meter ground plane is very narrow for use on 70 cm and only allows reasonable swr on the satellite frequencies. I find that a simple 70 cm 30 degree sloper ground plane gives me better band width and of course works better on the satellites than the 2 meter. The two meter is only being used due to my sloper being rebuilt right now. I agree on the comments you made about the TS2000, but have definitely found the the TS2000 lacking in it hearing sensitivity. For a complete DC to light rig, the Kenwood is great, but like some of the other features about the IC-910 and already have many HF (dc to light ) rigs such as an Omni VI Ten Tec, Yaesu FT-817 and FT-857 and another hf/vhf/uhf rig was not necessary. I find that my preference is the IC-910 due to the comments I have made. I know of many who really like the TS-2000. As I stated before I have the Kenwood TS711/811 which have been super units, but no longer supported by the new software now available. Reid, W4UPD Reid, W4UPD Mark L.

The TS-2000X allows adjustments of modem/TNC levels in/out of the rig, 910 does not. The TS-2000X has built-in TXCO and DSP, 910 does not (yes, they are expen$ive options). The TS-2000X lets you work mode A, 910 does not. The TS-2000X gives me the full rated power output on both 2M and 70cm, the 910 does not (same antennas, feedlines, etc.)---does anybody have the solution to this? Even with flat SWR the 910 cuts back output to about 70-75W on 2M and 40-50W on 70cm!! Bummer The 910 receiver is much better on 2M than my TS-2000X, which is actually pretty deaf on 2M(even after doing the resistor mod to improve receive).

[amsat-bb] Re: Icom 910H vs Kenwood TS2000
I am amazed at how many people take things stated out of context on this reflector. I never said that any of the arrays would not work due to being too narrow for satellite work. An individual asked about the problem they were having hearing the satellites and it was stated that if none of the other suggestions worked to consider that the arrays they are using are pointed correctly in the correct direction of the satellite. Pointing being off, the nulls could easily block the satellite's reception. The larger the array the more this might be evident. The larger the array, stacked arrays and even dish antennas, pointing becomes a bit more critical. Reid, W4UPD John Geiger wrote: I have used a Cushcraft 13B2 (13 elements) on 2m and a Cushcraft 719B (19 elements) on 70cm on the satellites with no problem.

Not to prolong this thread but Jerry's append (below) brings up another question. How much antenna is too much for satellite operation.

[amsat-bb] Re: Frustration
I concur with what Drew states here. I am presently using (not by choice) a minimum setup with a 1/4 wave 2 meter homebrew groundplane for 70cm reception. I have an in-shack pre-amp that I use when I get serious in working AO-71 but I hear it rather well above 20 degrees without the preamp. I am limited to about 20 degrees or higher due to using the ground plane and a Ringo Ranger II for the two meter up link. Above 20 degrees the ground plan works well but the Ringo begins to lose signal due to radiation angle. I recommend following Drew's suggestion and also insure that your array is pointed correctly. An 11 element array can be narrow enough to easily null out the signal if you are not in the 15 - 20 degrees beam width. Reid, W4UPD Andrew Glasbrenner wrote: Do you hear a noise increase when you power up the preamp? If not, are you sure you are getting power to it? Can you hear terrestrial repeaters, and does the signal change when you cycle the preamp power? Check your ins and outs on the preamp to make sure they didn't get reversed. Same thing for any diplexer you may be using as a high pass filter. More of the obvious...sure you are tracking correctly, and at the right time? I wouldn't suspect any of the cabling or adapters other than one being flat out broken. The preamp should easily overcome any shortcomings of the cable you've described. 73, Drew KO4MA ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] Re: IC910
I tried working AO-51 the last couple of days on !.2Ghz, but no luck. I thought I heard myself a couple of times but sure. There was more activity than I expected to hear and I noticed that although the transponder signal was good as usual, the signals coming through were lower from those I have heard using the UHF uplink when on. I was using the usual 435.300 downlink as I do not have my stuff for 2.3Ghz put together yet. My attempts to work AO-51 was an experiment which I really didn't expect to work as I have about 50 feet of 9913 which is actually in three sections to allow it to reach the rig (IC-910) with each section being spliced with a N barrel connector. Each of those induces a fair amount of lose, especially at 1.2ghz. Next, I had that running to a general purpose MFJ discone that runs from 50mhz - 1.3Ghz. So as I figure it, I probably had about .5 watts ERP to AO-51 at best, hi! I plan on building a reasonable 1.2Ghz, maybe the loop one shown in the books as they appear to work well. I may look at getting or making a 100 watt (2C39) amplifier. However, I did hear a couple of portables on the pass, so I suspect a reasonable antenna will work wonders. Not sure but I do not think the sat antennas will not do much good without considerable modifications. By the time you do that you might as well make one from scratch. They're not that difficult to make. Since I'm new to the 1.2Ghz operation, you might want to solicit from others that have more to contribute than I do.

[amsat-bb] Re: SO-67 22Nov2009 1410z eastern USA
May be a note of interest. First chance I had to try and work the new bird and noticed that I had similar problems to the drop outs as previously mentioned. However, in my case I discovered at the end of the pass that I had forgotten to turn on the tone! I wonder how many may still may not have their tone enabled or wrong tone frequency? I also noticed that the bird was quite strong on the arrangement I was using and did not bother to turn on the receive preamp. I was using my IC-910 running one watt for the up link on a Ringo Ranger II vertical and my down link antenna was a two meter simple ground plane which seems to work well on the satellite frequencies. It is obviously three time larger in wave length for 70cm and narrow (only has good swr on the satellite frequencies) but does surprisingly well. I also wonder is some of the the drop outs might be due to the tones over deviating on signals and not known since they are not heard. Suggested narrow FM would probably reduce that particular problem. Way to go Amsat-SA looking forward to more on time and sounds very good.

[amsat-bb] Re: adding UX-910 to radio
I concur with all of the comments that have been forth coming. I recently bought my IC-910H not knowing that the unit was going out of production. However, its replacement appears to be a Kenwood TS2000 type which includes HF as well as the satellite bands. Since I already have multiple HF capabilities, I wanted something that would be more satellite specific. I also have the old Kenwood TS711/811 units that I might sell but I have found them still good units even being over 25 years old. I have seen more and more 1.2Ghz activities in satellites and terrestrial and suspect that it will continue. In the meantime, HRO (Ham Radio Outlet) has reduced the price of the IC-UX910 unit to a nice value, and with their free shipping and no sales tax, I found it to be a good deal and bought one. It only took less than 5 minutes to install. I doubt if you would go wrong in the additional investment.

The same pot is used in both azimuth and elevation. The pots can do 360 degree rotation and therefore are different from standard pots.

They can answer that question for you. While you are at it as I did not think to ask would you inquire if they have any info on who made the potentiometer in the AZ and EL rotors for them and do they have a manufactures part number for it. I believe they are the same part. I am sure there are lots of folks here that would like that info.

Why so many you ask? I was going to order a few of the pots for the rotor as well while I was at it and found out they no longer stock them. If you have a 5400 I would call Yaesu and get some of the control box pots while they are still available.

[amsat-bb] Re: Got Yaesu 5400 rotor control box problem
This is similar to a problem I had some time ago and it was both bad pots. You have two pots to calibrate the meters and two pots for computer control. The computer control ones were very sensitive to EMI. I replaced both pots and the unit has been fine ever since. I had found the one end of the pots were open preventing accurate adjustments. Hopefully this is all that is wrong with yours. The pots were fairly inexpensive from Yaesu. I took and paralleled a regular 500 pot externally (alligator clip wires) to confirm this and found that I was able to adjust the unit. Regards, Reid Bristor, W4UPD John Price wrote: I have hauled out my spare 5400 rotor for field day and found I have a problem. The control box is not sending accurate readings to the computer. It works fine as far as the rotor and the meter readings. I know the problem is in the control box as the one I use for everyday operation works fine with this rotor. I have checked the voltages at the transformer and they are OK so I am now suspect of one or both of the pots that adjust output voltage. I when I connect it to just one side of the rotor I can not get it to adjust to 1023 in the calibration routine in the software. Connecting it to the other side shows the same result. What I do see is a value that bounces around at random. I guess my question is does this mean that I have two bad pots or is there some common connection between the AZ/EL output that would exhibit this result. Any ideas would be greatly appreciated.

[amsat-bb] Re: IC-910 Data Connections
I am using that very arrangement. However, I am using the Yaesu CT-39A cables since they were cheap and have the same mini-din connector. The xmit is not a problem since the same pin on the IC-910 is the same for either speed. However, I tied the 1200 and 96000 rx leads together and since you can't do both speeds at the same time, I found no problems with that configuration and no interactions. I am also using a DSP2232 that I use to use on my Kenwood TS711/811. Reid, W4UPD James Denneny wrote: I would invite comments on a recent change to cabling my IC-910H with my AEA DSP-2232 TNC. Until now, I have cabled the 910 main sub data port sockets to the 2232 five pin din radio input port. The cable was made up using the 910 data socket 9600 bps convention. I did this in order to communicate with satellite BB services such as GO-32. Unfortunately, this convention does not support 1200 bps. I would need to swap cables in order to switch RX audio from data port pin 4 to pin 5 for 1200bps AFSK. To get around this shortcoming, I am replacing the data socket cables with a cable using ACC port to connect with 2232. Icom manual says this should work for 9600bps FM mode or 1200bps FM/SSB modes. Does anyone know whether using ACC port vs Main Sub data sockets compromises anything? Jim K7EG ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] Re: Yaesu G5500 rotor trouble.
I tried once, but the last reply never came through AMSAT-BB yet. So I'll answer yours directly which also answered a previous one on getting the parts. I believe your G5500 uses the same elevation (G500b) as my G5400 late model. Also it probably has limit switches in the rotator which will prevent the down from working until it went up a bit. Mine still has a bad motor (actually the armature due to my own fault). As long as it draws current and the lamps dim on the UP selection, the motor itself is probably still good. * RESEND I find this hard to believe unless its related to the G5500. I just got done ordering stuff from Yaesu for my G5400/G500b elevation rotator. Unfortunately, the IPB I had with my rotor was for the G500a and the parts were wrong and I had to send them back. They did give me credit for the returned parts as well. I have a bad motor and they one they sent was for the G500a and was $85.00 However, its size kept it from being close to being able to be used. When I checked the G500b IPB and gave them the part number, it was $207.17!!! So I said forget it. I'd figure a way to fix it. The cap you can get anywhere if that is all that is wrong. Mine had over a pint of water and as such rusted and dried and packed the grease keeping the motor from working. I suspect you have little choice but to take it apart and confirm the problem. Again, unless it is due to being a G5500, I had no problems getting parts from Yaesu as recently as last month.

You can get a replacement from Yaesu for $10-15 including shipping. Replacing it is not hard, but it is very tedious and messy. Unlike other versions, the G-5500 has the capacitor in the motor housing rather than the control box. I had exactly the same symptoms you describe, and it was the capacitor in my case.
