how the hell can a STRAIGHT stacked vertical ... be elliptical poarized??

or is it interaction of the "corner of the roof" producing it??

in my view that stacked verical is nothing special but a vertical stacked antenna ... should produce a vertical polarized signal towards horizon (to reach far away repeaters) ... and only a low signal towards the sky

shoud not a quarterwave whip work better for sats??

or what about a 3/4 wave (with some high angle radiation) ??? should that not work better for sats??

greetz sigi dg9bfc

ps any links to the compac antenna?? did not find it

Hi Jerry. I set a Comet CA-2x4SR NMO in the center of the roof and a COMPAC 136-174MHz/400-480Mhz at the rear corner of the roof. Being elliptically polarized, this antenna has to be on a corner to work properly. I have tried many antenna combinations, including eggbeater types and I like this combination the best. Between the properties of each, I get a good signal. Perfect? No, but simple to rove and power to get into the crowded birds.  KC9UQR

Brad,
Did you build the antennas on your van or purchased?
If so, what manufacturer?

Brad,
WOW!. Thats great. Hardly any money spent on those antennas and you have been quite
successful working the birds. I will get back with you after the holidays for additional info.
   By the way, I forgot to mention that I have a new Yaesu FTM-400XDR.I'm sure I could
use it for the SATS along with my Kenwood TH-D72A.

I just purchased a d710ga as well. What are you using for doppler tuning? And how are you connecting to the radio? I've been using a Flex but would like to try the Kenwood for sats also. I'm interested in the details of your setup for the tmd710ga!

Subject: [Work-Sat] IC-9700 and the SATS

I wanted to ask everyone on the board that owns the  IC-9700 about how do you like it and is it great for the SATS and doppler effect?
I understand it also has D-Star, but that mode is rather dead in my area so I could care less about it.  I would have liked to purchase the
Kenwood 2000, but it is not in production anymore and I do not want to get a used one.
Your input is welcomed.
Thanks,

I'm going to check out the specs right now. I did not
know it was full duplex. All the better.

Jey,

There is a very simply reason it asks to access photos and files on your device, it uses that permission to save the received SSTV images to your images folder. However, if you don't want to allow it, or want to be able to try different settings for an improved capture, just record the audio with any audio recorder. You can play the audio back and have Robot36 decode it or use MMSSTV or other SSTV app on a computer to decode the signal.

Hi Bread,
How are things with you? Yes, I would appreciate it if you could send that file, but I will not be able to use it until some time in January because my PC computer
crashed and i have to either build or purchase another one from Micro Center which is about 30 miles north east from me. I'm using my Apple computer for e-mail.

Thanks Brad,
Great to hear from you again. I have been off the air for a while due to my daughter-in-law had a baby boy on October 10th and we have been spending a lot of time at my son's house.
I think you know the routine. LOL

I'll get back with you sometime this week. Tonight at around 23:23 to 23:35 my time EST, I'm going to try to at least copy the AO91 pass but it looks like it will be in the Atlantic Ocean east of N.Y.
Can't wait to get back in the flow of ham radio. I have a lot to learn and catch up with all the new modes.

Tonight I can only use the 19" whip. My home brew 2M, 8' boom, 7-element is in the garage and will not be able to set it up tonight.
I have a few adjustments to make on it and its already dark and getting colder tonight. I'm going to pull it down from the storage tomorrow
and set it up permanently. I was impressed with the results of using it when the ISS came over and contacted one of the local high schools.
