Hi Doug, Here is the best article on the subject with an explanation of why and what to do: http://www.amsat.org/amsat/features/one_true_rule.html Welcome to satellites! 73, Tony AA2TX AMSAT, VP Engineering --- - Original Message - From: Douglas Phelps dphel...@ameritech.net To: amsat-bb@amsat.org Sent: Wednesday, June 8, 2011 8:59:51 PM Subject: [amsat-bb] SSB Operation on the satellites. I am new to the satellites. Got to where I can hear my downlink if the bird is higher than 15 degrees. My question is about handling the doppler shift. If you do not have a sat program automatically correcting you rig frequency, what is the most common or preffered technique? 1 - Hold the TX steady and adj the RX for doppler or 2- Hold the RX steady and adjust the TX for doppler? I know this must be a basic question but I am learning. Thanks, Doug K9DLP ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] SSB Operation on the Satellites
Hi Satelliters, Might cause some flames with this but here goes: With a good few years of operating on the SSB sats, AO's-10,13,40, RS10, FO-20,FO-29 and 98 countries confirmed I can agree totally with the one true rule in theory. When stations at each end of the QSO use the method it works flawlessly, I have done it with QSO partners using Fod track and with Instantrak computer Doppler correction, but there is the problem. Many of the stations that you want to work will be using manual tuning methods, so as you maintain your frequencies at the satellite, according to the rule, your QSO partner will have to search for you. Then when its your turn to transmit he will have to search for you. The practical solution that I and I believe most of the ops. I have worked seem to use is to have short overs and to adjust frequencies the TX to try and keep the QSO in a fixed spot on the receiver. Following the other often recommended method of adjusting the higher frequency irrespective of its function, up link or down link, cause QSO's to drift across the pass band causing problems for other users. The other point worth making for newcomers to the SSB birds is to start on the easy passes/satellites first to get the knack of manual tuning. For example, try VO-52 with its 2m downlink, and to pick low elevation passes where the rate of change of frequency due to Doppler shift is less. Don't expect to get it right with near overhead passes of FO-29 until you have delevop your skills. We were all beginners once so don't be afraid to have a go and make a few mistakes. I am pleased to say that in my experience the SSB satellites have a great user community who maintain high operating standard and welcome new ops.

[amsat-bb] Re: SSB Operation on the Satellites
A rookie observation…. That article was written in 1994 —well prior to the state of the art in full doppler correction. I use MacDoppler for adjusting the VFOs and it happily adjusts both of them. The ONLY time I run into a problem where the received station is moving is when it is clear someone is NOT using full doppler correction. I would humbly submit that this being 2011 and both SatPC32 and MacDoppler handle full doppler correction, the exception should be the One Tune Rule and the norm should be full doppler correction. I know that when I work someone that is also using full doppler correction, it is a joy as the radio just happily stays tuned and we move during the whole pass. Is the state of the art still such that we are all using radios that do not support full doppler correction? I will put my flame suit on now… 73, Tom Tom Schaefer, NY4I n...@arrl.net EL88pb Monitoring EchoLink node KJ4FEC-L 489389 DSTAR Capable APRS: NY4I-15 On Jun 9, 2011, at 6:23 AM, John Heath wrote: Hi Satelliters, Might cause some flames with this but here goes: With a good few years of operating on the SSB sats, AO's-10,13,40, RS10, FO-20,FO-29 and 98 countries confirmed I can agree totally with the one true rule in theory.

[amsat-bb] Re: SSB Operation on the Satellites
Certainly desirable Tom, but I've been in Amsat and on the birds since the '70s and it wasn't until the last couple of years that I got my PC hooked to my FT-736R! And then just this year to get it hooked to my FT-817 (IF) radio. I will say that there's nothing better than PC doppler and rotator control, having used 3 hands many times in the past. I would be a terrible drummer! But for all fairness, there are a number of reasons that one may not have PC aided doppler correction so the one true rule still holds good. Not a flame, just another opinion. I'm sure this thread will get some mileage! 73, Jerry NØJY A rookie observation .

[amsat-bb] Re: SSB Operation on the Satellites
I always varied the transmit. This way the person I'm talking to as well as any other listeners are all on the same freq listening. Growing up on the birds when you had to twist the BIG knob to keep everyone on freq is not not a big deal. And to this day i still don't know why it seems to be a problem now days. It all just takes practice. just like in field day coming up our club tries to get the non HF users to come out and try it. and at times it's incredibly painful to watch the guy that operates Channelized radios. IE: 2 meter FM How it will take them minutes to finally be within 500Hz of being on freq of a ssb signal. And even then most of the time they will be calling someone when it's obvious they are no where near on freq. then it's twiddling the big knob again going right past on freq spot and again try again off freq. Where a seasoned operator will tune them in in 1/2 a sec coming in from one side and stop dead on freq. it all just takes time on the air. simple.

[amsat-bb] Re: SSB Operation on the Satellites
OK my brain may be playing tricks, but if you vary only your transmit frequency such that you always hear yourself on the same downlink frequency, isn't it true that the other station may not necessarily be hearing you on the same downlink frequency and is chasing you anyway? Your doppler is +5kHz (for example) on the receive, the bird is just about to pass overhead of me though so my receive ferquency goes rapidly from +2kHz to -5kHz, your transmit tuning has no relation at all to what frequency I am listening on. Then the bird goes past you and you suddenly switch down 5kHz, so I have to follow you on my receive. Or am I nuts? (Quite possible, come see where I work and you will understand!)

[amsat-bb] Re: VO52 and verticals
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').

[amsat-bb] Re: SSB Operation on the Satellites
Jerry's correct. If you only adjust your transmit frequency, such that your receive frequency appears to stay the same -- then you're automatically correcting for your own downlink doppler, but not for anyone elses. Other hams in the footprint will still have to chase you. The only way to stick with the one true rule is to adjust *both* uplink and downlink during the pass. That being said, adjusting the higher (UHF) transmit frequency on VO-52 and AO-07 only (ie. manual control) will get you pretty close, and you won't drift a whole lot. I hear plenty of hams doing this, as long as there are just one or a two QSO's going on, they don't drift into each other very often. 73 de Dave KB5WIA / CM88 SatPC32 with 2xFT817ND On Thu, Jun 9, 2011 at 7:35 AM, n...@lavabit.com wrote: OK my brain may be playing tricks, but if you vary only your transmit frequency such that you always hear yourself on the same downlink frequency, isn't it true that the other station may not necessarily be hearing you on the same downlink frequency and is chasing you anyway?

[amsat-bb] Re: SSB Operation on the Satellites
Hi! That being said, adjusting the higher (UHF) transmit frequency on VO-52 and AO-07 only (ie. manual control) will get you pretty close, and you won't drift a whole lot. I hear plenty of hams doing this, as long as there are just one or a two QSO's going on, they don't drift into each other very often. Actually, if stations would spread out a bit more on the transponders, this would be even less of an issue. There is so much space that goes to waste on these transponders, when everyone seems to never go more than a few kHz up or down from the center. Sometimes, everyone appears to be jammed up around the center separated by 1 or 1.5 kHz between signals. When we have transponders with 50 to 100 kHz to play with depending on the satellite, that seems crazy. At least there's room where someone can go far away from the center to do testing and not bother those around the center. I'm one of those who does not use computer control, operating portable stations in the field. I try to follow the portion of the One True Rule about making adjustments on the higher of the two frequencies when not using full computer control. Sometimes I have to make adjustments on both frequencies to keep up with those who are fully computer controlled. I use an FT-817ND as my transmitter, and either a second FT-817ND or a Kenwood TH-F6A HT for my receiver (that HT has an all-mode wide- band receiver in it). Whenever I get a home station again, or find a laptop/netbook with an LCD panel that I can see well in the field, I will take another look at putting my 817s under the control of SatPC32. 73!

[amsat-bb] Re: VO52 and verticals
As I currently live in an antenna-restricted subdivision, I have been experimenting with low-profile antennas for a couple of years now. My experience has been that verticals are iffy for a couple of reasons: not enough gain at low elevations when the path is longest, a deep null above 40 degrees or so, and fades due to polarization mis-matches. That being said, I seem to do alright on VO-52 right now with a 1/4 wave UHF groundplane on the uplink and a well-hidden 2-meter Eggbeater on the downlink, at elevations between about 20 and 40 degrees. I am in the process of building a turnstile for 437, which I hope will improve both my uplink on VO-52 as well as my downlink on all the other birds.

This is a great thread. Well, I am going to continue with full doppler and just resolve myself to tuning in some people that are not quite there yet.
