Hi Robert, NH7WN Yes KKS-1 in beacon mode of sending time and date only our friend Mike DK3WN has a nice Satblog daily updated with a lot of fresh and new information. http://www.dk3wn.info/p/ thanks Mike for this great work. 73 de Nader, st2nh www.st2nh.com

Optimum HT for FM satellite use?
by Gordon Bousman 01 Feb '09

01 Feb '09

I'm getting started in satellite work and interested in purchasing a suitable HT for portable satellite use using an Arrow antenna. Wondering what is considered to be an optimum HT especially considering ease of managing the Doppler shift during a pass. I understand that the HT must be full duplex capable and thus rules out some models. Thanks, Gordon, NW7D

STARS observation

Hello All, Just heard both mother and daughter CW transmissions from STARS using 2 receivers. They transmit independently; not synchronised to start alternately. Also heard PRISM and KKS-1 transmitting a date and time message. 73 de David VK5DG

If anyone copied my image on AO-51 on 1/31/09 around 2330Z, please send me what you received. I would like to write an article for the local radio club and it would be nice to have a received image (you will get full credit for the image!), Joe KC8RAN

Re: FT-736 tuning dial problem ? Any ideas ?
by Glenn Miller 01 Feb '09

01 Feb '09

It sounds like the tuning shaft bearing is seizing. I'm not familiar with the mechanics of that rig's tuning shaft, but I've had similar happen with other rigs. You may be able to access the bearing by removing the tuning knob and clean and lube it without removing/replacing it. Good luck. 73 Glenn AA5PK _________________________________________________________________ Windows Live™: E-mail. Chat. Share.

FT-736 tuning dial problem ? Any ideas ?
by Alan Sieg WB5RMG 01 Feb '09

01 Feb '09

Strangest thing. I've been using my FT-736 since 1989 - trouble free. There is a dimmer or noisy connection somewhere in the house that sometimes give me fits, splattering all over the 2m band. Well this evening it was S9+ and I could barely copy ISS. After the pass I'm spinning up and down the band in USB hoping to find a freq with the most noise, and the dial starts to drag. Only slightly at first, but over a 5 min period it got worse and worse, to where it was actually squeaking some. Then I could no longer use the spinner, and it was getting hard to turn. Now I have to use several fingers grip, and it squeaks a lot. The freq does change with rotation, but now I have stopped messing with, as it is nearly too tight to turn !!! Has my 20 yr power-train warranty just expired ? What a difference 10 minutes can make. Tell me this isn't happening !.! Surely someone has had experience with the tuning shaft in this rig, and can offer some guidance as to what might be going on. I'm gonna remove the top and bottom, so as to un-hinge the front, but I doubt I can see anything obvious. But I'm gonna look. Suggestions are welcome, except the ones like "It's gone bad - just send it to me - buy a new radio..."

KKS-1
by Robert Smith 01 Feb '09

01 Feb '09

Aloha I am looking for the "easy way out" here. I've loaded up the current Celestrak keps for the new satellites. Names have now been assigned to KKS-1 and PRISM (amongst others). Several days ago I was copying KKS-1 and PRISM with significant separation in time. Suddenly the new keps have them orbiting much closer. Since I copy in FM I have to translate a recorded signal on audio software. This morning I copied (per the new keps) what I thought was KKS-1 and then switched over to PRISM. I experienced "fading" on both birds. Later "translation" of the first CW signals revealed the following: 609/01/2403:17:00 609/01/2403:17:00 609/01/2403:17:00 ,,,,, etc etc. This data does not resemble previous KKS-1 beacons I have copied although the time and freq. appears very close to the new KEPS. Certainly, I will continue to investigate but perhaps someone already knows the answer/s?? Mahalo for your kokua (Thanks for your help) Respectfully, robert, NH7WN Honolulu

AO51 SSTV: thanks !
by Henk, PA3GUO 01 Feb '09

01 Feb '09

To the AO51 Operations team: "THANKS For SSTV mode (145 up, 435 down) the past week" Was a lot of fun, in fact I have done my very first SSTV transmissions ever, cool ! Impressive to observe that even at very low elevation pictures are still quite readable. When AO51 was for both OZ2MA and me at only 5 degrees elevation, OZ2MA could still see it.

> FWIW the FT-51R has memory tune > as well as full duplex, ... And another thing the FT51R has is DTMF Text Messaging. This is compatible with the TH-78 as well. There are dozens of thousands of these radios out there, and we hope to integrate their TEXT Messaging capabilties into the global D7 and other APRS text messaging and Email system as part of the Universal Ham Radio Text Messaging System. The goal is text messaging by callsign alone, between any hams, anywhere, anytime, using any device. see www.aprs.org/aprs-messaging.html All we need is a little software as a gateway. ... So we are looking for an idle programmer... Bob WB4APR
