SO-50 1920Z Pass
by Chris Pohlad-Thomas 05 Jan '19

05 Jan '19

Just checking to see if anyone could hear me on this pass a little while ago. I don't yet have an extra BNC to hook my scanner up to my arrow for full duplex, so running off a VX-7R. -- Chris Pohlad-Thomas KC1E

FT-857 and Omnirig
by NA1SA Loon 05 Jan '19

05 Jan '19

I'm using PstRotator with Omnirig to control my new FT-857D. I managed to get the computer and radio to connect, but I cannot get the TX and RX frequencies to display on the OmniRig side of PstRotator, My settings are... Rig Type: FT-857 Port: COM 3 Baud Rate: 4800 Data Bits 8 Parity: None Stop Bits: 1 RTS: Low DTR: High Poll int ms: 500 Timeout: 4000 When in connects to the radio it only shows the RX frequency in OmniRig and it keeps changing the radios VFO to display a shortened frequency number... instead of 145.950 it shows 145.95. I then get a TX ERROR msg when you push the PTT and I end doing a reset to get the radio out of this mode. I'm stumped... Loon

Sat Contacts
by James McIrvin 04 Jan '19

04 Jan '19

Good evening all. I have been trying to make contacts this afternoon, after finding that I could start hearing myself on the birds which I had not been able to do before. I tried and I had a couple of folks respond to me, however, I was not able to pull them out of the noise. Sorry about that, just a newbie trying. also trying to tweak things so I can hear it all and learning how things work. I don't mean to cause anyone issues with me trying to work the birds, just trying to figure things out. So if you did hear me sorry, however, I will get things figured out at some point. Today was a good day so far trying to work the XW 2 birds. Since I have the ts2000 there is a birdie that kills some of the fm work which does not please me in the least. However, I will get this figured out. I just ask that you bare with me and also if you can give me any pointers that would be great too. Have a great weekend everyone and maybe we can work something out on one of these things. 73 de Jim N1IPA <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_cam…> Virus-free. www.avg.com <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_cam…> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>

I tweeted that I forgot my tape recorder and noticed it was gone on my boom so I tried to write calls on my wrist. I got one good one and one partial. ND0C Randal is okayK9ITW - Bill is okay But there were two others I missed before these two at the begin of the overflight in CN87. Sorry to goof up like this and thanks for the help JohnN7AME

Soundcard Packet to ISS
by Les Rayburn 04 Jan '19

04 Jan '19

Now that I’m back on the birds, I’d like to try my hand at making QSO’s using the ISS Digipeater. My IC-910H is set up for sound card modes—I use it successfully with WSJT for meteor scatter work. What is the best software for doing packet work with ISS? It does not have to be freeware—happy to pay for a good product. 73, Les Rayburn, N1LF 121 Mayfair Park Maylene, AL 35114 EM63nf Member WTFDA, IRCA, NRC. Former CPC Chairman for NRC & IRCA.

Greetings to all FUNcubers for 2019. FUNcube 1 is now back to "Educational" mode after the holiday period. Please keep tracking and sending in telemetry as we try to better understand the spin effects over the next few months of full orbit sun. Thanks, Brian (G4BIP)

Thanks for sharing Rick, it helps to compare notes. I have experienced the problem with a single coax feeding a full duplex Icom W32A HT as well as two separate coaxes feeding two radios. The front-end gets severely de-sensed esp when the V/U frequencies get close to harmonic relationship. I guess I need to investigate further. 73!Umesh, k6vug On Wednesday, January 2, 2019, 5:00:36 PM PST, saguaroastro <saguaroastro(a)cox.net> wrote: Umesh, I have not experienced any of that in either mode.

Kenwood TS2000 control versus Icom IC9100
by James McIrvin 04 Jan '19

04 Jan '19

I would like to find out which unit has a better tracking for doppler and general connectivity over all. I have been fighting with this TS 2000 keeping my connection with the pc going. I am about ready to deep six this thing. I have gone to a true IO card for the serial connection, Not a USB converter, changed the speeds to match in the settings in both radio and pc. tried different ports and things like that and at times it will track fair and then other times it does not do anything. I have restarted the pc and the radios, shut them both off and then restarted and still, I am having issues. I would like to have a rig that is going to work with Satpc32 in a reasonable fashion. Just keeping this thing working is taking the fun out of trying to get on with the birds and ready to change if it is going to work better. However, I am looking at general input from those that have used these rigs and if they have had good luck with them or if I am asking for something out in left field. Thank you. Jim

Doug, I been thinking about this as well. One antenna (arrow) for those birds with antennas at 90 (SO-50), and another for those birds with them in line. I've been looking at parallel designs(think "trident") e.g. take my elk, use that for 2m, and have a clip-on parallel spot for a 432 or 1.2G beam. Tired of doing the TX-90-degree-twist. Bill W1PA
