[amsat-bb] Arecibo
Hi All I have a KLM 436 with 1 db preamp I did not here them yesterday. I have about 2 db of sun noise. The question I have for those who copied Arecibo yesterday how much sun noise do you have in a 2.4 KHz band with filter?

They have an annoying birdie right smack dab on the downlink of SO-50 and AO-27 but both of those are FM sats. You can work around the birdie with a preamp but the pass time is shortened a bit because you are waiting for the receive frequency to get a little bit away from the birdie so you can hear. I don't know of any issues with SSB/CW sats though. Icom is coming out with a new radio that has HF plus sat capapbility but for the price I've heard you could just about buy a Flex 5000A and add the soon upcoming V/U module for not much more. The Flex 5000A is cutting edge technology but you have to get over most hams confounded affinity for knobs. I just got my 5000A today. I chose it over replacing the TS-2000X I used to have with another. It will be awhile before I can afford to add the V/U module but I'm willing to wait because IMHO the Flex is head and shoulders above any other radio on the market today. 73, Michael, W4HIJ On 4/16/2010 12:18 PM, Jacob Tennant wrote: Was wondering today after searching around on the internet, what radios are people using for satellite operations as I noticed the ICOM IC-910H and the Yaesu FT-847 are now discontinued?

[amsat-bb] Re: Radios for satellite operations
Can the K3 do full duplex in the same band? Elecraft's FAQ seems to indicate that they do not support this mode: Can the subreceiver provide unbroken audio using any antenna input while the K3 is transmitting?' This is full duplex operation, which is very difficult to do inside a single cabinet. However, it may be possible if you're using the transverter I/O (0 dBm TX power). We'll be testing this case and will post full specs later. Does the firmware support this? I am very interested in your experiments. Will you need to modify the DEMI transverter IFs? - Duffey On Apr 17, 2010, at 12:44 AM, Edward Cole wrote: Of course, each to his own choice.

Today on my single M2 antenna, many times they are Q5. Their amp has made a difference from yesterday when they were outputting only about 30 watts or so. For those who want to hear them live from a real antenna (25 meter dish!), check out this link: http://websdr.camras.nl:8901/ Move the frequency slider to about 432.044 and they are 20dB over S9! Maybe one day, maybe one day. Hmm, do I have enough room in my yard for a 25 meter dish? Also, I hear them much better on RHCP. And I got my money's worth on my receive preamp. Without the preamp I can't hear a thing. 73 de W4AS ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] LVB Tracker USB serial port driver for Windows 7 x64 Success
In response to my posting yesterday I received one suggestion to use a Vista driver. It did not work. What did work is the following: I downloaded the following zip files from http://www.dlpdesign.com/#Drivers . http://www.dlpdesign.com/cdm20600certified.zip http://www.dlpdesign.com/cdm20600dlp.zip I installed the drivers in cdm20600certified.zip but although the driver appeared to install, that was not sufficient. I then installed the drivers in cdm20600dlp.zip. These are not certified drivers. I ignored the warning. They work fine with SarPC32 so far. 73, Bill NJ1H ___ Sent via amsat...@amsat.org.

[amsat-bb] Re: Arecibo
So, I had pretty marginal copy in both SSB and CW, neither of which were quite good enough to hold a QSO. The odd thing is that CW did NOT improve things, even with the narrow filter on my FT-736R. The antenna is a 2x16 CP thing I picked up at a swap meet (so I don't know the brand). My copy was better with the CP relay UN-energized, so either it's wired backwards, or something is broken. On the man-made satellites, I have used both polarization settings, so I know they both work. Puzzle. There's also a no-name preamp up there, after a bit of coax to get around the rotor. Below the preamp is mostly hardline. Turning on the preamp results in a small but noticeable rise in the base noise floor, so I believe it is working. And I Just got down from the roof, after checking the aiming using the sun. No problem there. I even played with my W9GR DSP box, trying to pull out the signal. Didn't help much. Don't get me wrong - it was a thrill just to hear the moon. But what's wrong with my setup? The only other thing I can think of was that the moon was north-east of me at the time, and that means aiming through a bit of oak tree. Is that the problem?

I had to energize the relay on the antenna in order to hear them. I assume it's RHCP normally, and LHCP when the relay is energized. I actually had better copy during the SSB portion than the CW, but am not sure why that was. --Mike WQ5C On 4/17/2010 4:31 PM, i8cvs wrote: Hi Bob, W7LRD What polarization have you used on your 40 el cp ? RHCP or LHCP ? I am sure that with LHCP it was a very consistant signal and with RHCP nothing was heard. Please confirm !

I wish they would use dxpedition qso methods for more qso/hr. This is a very finite opportunity. Had fun anyway, better luck tomorrow. 73 Bob W7LRD ___ Sent via amsat...@amsat.org.

[amsat-bb] Preamp mounting?
Hi folks, So, a follow-up to my previous message. All this discussion about EME got me thinking... We're always taught to put your preamp as close to the feed point as possible, but as with everything, there are tradeoffs. Where should the Preamp be mounted? Choices: 1 - on the antenna boom, at the feed point (or attached to the CP relay) 2 - on the rotor cross arm 3 - below the rotor, where the flex transitions to the main feed I'm thinking that #1 is a problem. Yes, it's the shortest run, but you've got the weight of the preamp at the far end of the antenna, unbalancing things. Depending on the antenna, it might be right in the middle of a bunch of elements, so putting a metal box there might upset the antenna's performance or impedance. It's would also be subjected to the strong RF fields of the antenna during transmit. #2 is probably the best; fairly short coax run on the antenna side, and somewhat outside of the RF field. #3 (what I have) is most convenient, and has one less set of connectors to go bad, and one less wire to snake around the rotor. Weather proofing is easier when the object being proofed can't move, and mounting the preamp on the tower, for me at least, is a lot easier. And, it's not THAT much more coax to the antenna.
