I've found myself playing with amateur radio in my observatory because of all the cloudy nights in Southern California over the last year.  In fact it has been so horrible for the last several months. So while having no images to process, I have started working with the software defined ration (http://www.rtl-sdr.com/) - an incredibly inexpensive device which receives from about 30MHz to over 1 GHz.  After I get my license I will be getting a proper rig for transmitting.

 

So my question is, is there any other Observatories which are outfitted with amateur radio and do you chat with other observatories/astrophotographers over the air waves?

 

thanks

Jim

Once I get a telescope, I'll be using the scope right outside the house and expect I'll be monitoring my favorite bands while outside.  I have an sdr radio (anan-100d) that I can run with a laptop or Android tablet; I should have this running in the next week. 

     Good luck getting your license.

Haven't yet. Perhaps we should start a Cloudy Nights net.

It is truly amazing how many ham ops have an interest in Astronomy.  Even the Brother's Net has an evening dedicated to astronomy trivia.

There were a couple of nice Celestrons at the last Breezeshooters Hamfest

It would be pretty cool connecting with other imagers over say VHF (only saying VHF since I don't have my General License yet and erecting an HF antenna in my tiny backyard is not happening. )  Comparing weather conditions, seeing, and especially transient events etc between observatories.

This sounds very interesting. I agree that VHF would be a great way to go. It's more accessible due to cost of equipment and antenna requirements. A net could be started using IRLP which would allow anyone in the world to connect on their VHF radio.

The people at http://Papasys.com invited me to provide them a presentation on astroimaging.  So there is an interest from the mainline ham radio folks.  I am hoping that some of their very seasoned and knowledgeable hams would advise me on the best path to follow.  They already suggested that I use UHF and connect through the Papasys repeaters and reflectors.  I can connect into the repeater on top of Mt Palomar at 448.540 MHz.  I recently got a Baofang UV-5R handheld UHF radio.  I'd love to do a CQ with an astroimager if we can set a schedule and frequency.

 

I passed my Technicians Exam and am waiting to receive my call sign.

I can also use ("see") the repeater at 146.520 MHz.

I control my Observatory remotely from my "Shack", where I listen to the HF Bands on my Kenwood HF radio. The Observatory is in the back yard. I've often thought it'd be nice to rag chew with other Amatuer Astronomers while monitoring the imaging sessions. I could do HF or VHF, although I've never tried the VHF over the Internet thing.

We need a volunteer who knows how to setup and work IRLP to organize a net.... Or maybe even a "meeting place" on the air where people could check in each night.

Send a PM to SL63 AMG he is big time into ham radio.  He has a station set up in the Bahamas or somewhere down there.

Jamaica to be precise! K1LZ and I (KY1V) built the 6Y1V contest station. Consists of 4 Icom IC7800, 4 ACOM 2000A's, a 160m Delta loop, an 80m 4 square, stacked Monster SteppIR's on a 140' tower consisting of a 3/3 stack on 40m, a 4/4 stack on 10m/15m/20m at 70' and 140', as well as a 110' rotating tower with stacked 6/6 on 20m, 6/6 on 15m and 7/7 on 10m.

 

Currently, and quite temporarily, I am in an HOA restricted neighborhood in Arizona and I am inactive, but in a few months I am moving to a 120 acre ranch about 25 miles north of Prescott. I have a 180 foot of Rohn 45G and a 55 ft crank up tilt over which I can install there when I get ambitious.

 

My call is KY1V. I have been a ham since 1976 and have an extra class license.

I met my wife in Prescott, love the place. (Except it got big! Spent a couple of days there this sping and it's grown since I left 33 years ago)

 

Let me me know when you are QRV, we'll set up a sked.

Hey Larry,

You do MARS radio by any chance? I talked to a guy from Bloomington yesterday for a phone patch.

Chris,

 

I used to be a member of Navy MARS but dropped out about 10 years ago. I just saw a note in the latest QST that the DoD is going to shut down Navy MARS. Kinda too bad, there were some very competent operators in the group.

 

What' your callsign Chris?

We're the Tigers out of Ellsworth.  :)  We really appreciate all the help you guys give us.  You have no idea how nice it is to have BLOS communications without relying on a satellite.

I live in Gillette Wyoming now, just moved from Sheridan, call sign is N7JZE.  Haven't keyed a mic in over 20 years.  Keep my license current though.

Nice Bob!  I cut my teeth on the  DX-60.. way back in 1970!  Lots of memories, up all night  working  Africa, Antartica... having loads of fun as a High School student .  

thanks for sharing!

Those were the good days!  I had a Realistic DX-150A communications receiver.  I gave it away and later picked up a ICOM  R8500 (impressive, but I have to use it more often in order to burn the feature controls into my memory).

I was trying to reproduce my first system from '64. I had a Mosley CM-1 and a Globe Chief Deluxe.

I'm going to learn how to build radio telescopes. I just moved to a 120 acre ranch with lots of space... pun intended.

 

Anyone want to help?
