ARRL instructor and AMSAT-NA Ambassador Clint Bradford, K6LCS, Will be presenting his "Working Amateur Satellites With Your HT” session at the Saturday, August 15, 2020 meeting of the Team Radio GA in southeast Georgia. The session will begin at 9AM Georgia time. Team Radio GA (TRGA) is a growing ARES / EmComm group, whose region covers the ARRL’s District 8 in Georgia. Led by Jerome Erickson KK1JE, TRGA was featured in the July, 2020 issue of the ARRL Georgia Section’s newsletter, “Georgia on My Mind.” The groups Jerome has organized focus on digital and emergency communications. Refreshingly, Jerome told the newsletter editor, “I believe that the privilege to operate on the many frequencies we are granted we should make an effort to give back to our communities through radio communications.” TRGA’s expanding Web site is … http://trga.us/ Clint K6LCS has made it his mission in his amateur radio life to show Hams that they really can work a few FM voice satellites with equipment they probably already own. To that end, he has given his presentation more than 100 times to audiences who genuinely desire to expand their ham experience - to clubs, conventions, and hamfests in North America and Canada. An attendee of Clint’s session at the club a couple years ago wrote: "K6LCS gave a fantastic presentation on amateur satellites. It was most informative and entertaining. Clint's passion for the subject was evident, and I would imagine that the club members individually and or in a group will be eager to try satellite contacts in the near future." “We will be using Zoom Video Communications to conduct our session,” Clint advises. “I would much rather be in a room, LIVE, with my audience, but it’s cheaper with Zoom than air fare to Savannah's International Airport … “ Clint always welcomes questions before his presentations.

That picture was all over amsat or some website and reminds me of lots of reading and research before i was able to make my first contact with a ht !
Can you better explain when and how to use multiple frequencies to assist with doppler shift. Is it only used for Rx or is also used with Tx. I use low watts, 5wt or less to transmit and I never hit a bird until it is almost over head.
Check out the frequency chart at http://www.work-sat.com. For working "portable," we only have to really consider the Doppler phenomenon on the 440 side of things. On a decent pass, there is only about a +/- 3 kHZ deviation in frequency on 2m ... but a whopping +/- 9kHZ deviation on 440! If you can use two radios - one for RX with an earpiece and a second to transmit - you will be able to hear yourself coming through the satellite. That is termed, "full-duplex."

Are you still using the email address listed in your profile? If so, I just sent you an invitation. If not, someone else may be receiving it ... (grin) Clint
Any idea why my ts2000 isn't even close for the uplink downlink when you try to use the sat function? I gave up trying to figure it out. Even more disappointing was learning the second receiver only does am or fm so no full duplex SSB sat work. I do everything by hand anyway so tracking while holding a ts2000 is completely out of the question. I use 2 ht's or just one and have a pvc pipe on a tripod holding a m2 4 el 2m and a cheap cushcraft 440 beam. its certainly a challenge but fun
Try posting in the satellite/eme sub-forum. You'll get much better responses. Your TS2000 does indeed do full duplex in SSB, not sure why you are unable to do it (plenty of sat regulars using or have used the TS2000 for linear sats).
Steve Ford touched upon sat work in this QST magazine review of your rig ... https://www.centralmiarc.com/docs/Reviews/ts2000.pdf
