Lilacsat 2 beacon

This evening at 0000 utc I listened and taped the beacon as the satellite passed my qth and it wasn't loud but very audible. So my question is... What software will interpret it and is it available to amsat members. Also, I use My Sats app on my phone and the up links and down links seem to confuse me and I would like to work it if possible. Is it FM? And are there two sets of frequencies. Thanks for any information. JohnN7AME

Yaesu FT-857D and Doppler
by Hasan al-Basri 01 Nov '18

01 Nov '18

I have been told that this radio will not accept CAT doppler adjustments while it is transmitting. I definitely see that it doesn't, but don't know if I might be doing something wrong. Here is how it behaves: If not transmitting, doppler correction works perfectly. As I assert PTT, doppler adjustment stops and I slide up the band...pretty quickly on high passes. If I hold the ptt for more than a couple of seconds, I will go right out of the passband of my 2.2 kHz filter...and of course become unintelligible. As soon as I drop PTT, and key the mike again, I'm dead on freq...and as long as I hold the PTT on, I drift up the band. *It appears the the FT-857D will not accept CAT commands while PTT is asserted.* At this point I need to know that there is no real solution to this problem with this radio. If that's true, I can get pretty good at doing this: 1. Assert PTT and start talking. 2. Grab VFO knob, adjust as I talk to keep sounding good. 3. Drop PTT and begin to listen to other station. (at the drop of PTT, tx freq snaps to "proper" place that it couldn't get to when PTT was asserted) 4. My turn to talk: Assert PTT and I'm dead on freq where I belong. Basically, I'm doing manual uplink adjustment to freq while I'm talking and letting the CAT adjustment for doppler to take place (to the uplink freq) while I'm listening. *If there is a better way to do this, please advise*. Note, it is not practical to drop PTT quickly enough and often enough to prevent the problem...I can only speak a couple syllables at best, before I slide away. Equipment and Setup: Rx: SDRPlay RSP2 Sofware Defined Radio with SDR Console v 3.03 providing Doppler to Rx Tx: Yaesu FT-857D controlled as External Radio by SDR Console v 3.03 providing doppler correction to the External Radio. p.s. I have tried other doppler control programs and they behave the same way. Any and all help would be most appreciated, even simply: You are stuck with the way you are currently doing it. 73, N0AN Hasan

PSK31 on PSAT -- it works!
by Scott 01 Nov '18

01 Nov '18

Now that I have successfully transmitted a 10m PSK31 signal to PSAT (NO-84) and have found it on the 70cm FM downlink, I feel foolish that it took me this long to figure it all out. The antenna for 10m is a My Antennas EFHW-8010 (130 ft. wire), so it did not require a beam or anything directional: http://myantennas.com/wp/product/efhw-8010/ Here is a tweet w/ screen shots that I posted: https://twitter.com/scott23192/status/1058007013265944576 ... and here is the excellent how-to from 2M0SQL that finally got me going with this mode: https://www.2m0sql.com/2018/10/29/using-the-no-84-psat-psk-transponder/ Hope to complete a QSO with another station soon! -Scott, K4KDR
