Thanks for posting all the information.  Reading and understanding prop prediction and values is one thing I really need to work on.  Everyone is on the air now talking about a huge sunspot today.

Try this link: http://amzn.to/1bbccDx. Best $20 in Ham Radio, although receive only.

Then download free software from (for example) www.sdrsharp.com.

Heh! I like that.^^^ I'm going to have to give that a try.  ;D

^ Those are very helpful pages on this mode. They got me up and running quickly and properly. Thanks for putting those out on the web.

I've been keeping an eye out for your call sign but haven't seen you yet. One of these days though.

I mostly run PSK-31 or JT-65A. I have been dabbling in Hellschreiber lately too. I haven't made a QSO on it yet though.

I still have to try Olivia but I plan to soon.

General discussion (QSO) / n00b introduction - K3WHO

Greetings all! My name is Jason and I've been an amateur operator since 2000. My main radio interests are HF digital modes and satellite operation. I've been dabbling a bit in Hellschreiber a lot lately too. I tend to migrate from one thing to the next. There's just so much interesting things to try in amateur radio. I'm looking forward to seeing everyone around the forums and hopefully on the air too!

I just picked up a pi, and intend to use it for ADSB and general reception. Idea is to convert from RF to TCP as close to the antenna as possible. My plan is to mount all of this at the top of the chimney.

See http://zr6aic.blogspot.com/2013/02/setting-up-my-raspberry-pi-as-sdr-server.html for someone else's work on getting things set up.

Awesome idea!

Hey, Folks.

I write the monthly columns covering radio propagation and space weather, in CQ Magazine, Popular Communications, and CQ VHF Quarterly.

I use various software tools, to help both analyze propagation, and also predict the conditions of various radio paths that I wish to engage (for DXing or other hunting).

One of the tools I use is ACE-HF Pro.

ACE stands for Animated Communications Effectiveness, a coverage display technique originally developed for U.S. Navy submarine communications. ACE-HF PRO, Version 2.06, is the System Simulation and Visualization software written for HAM Radio Operations and Short Wave Listener Operation. See the reviews, below, for the full details on the features for Ham Radio and SWLing.

The ACE method shows a sequential series of coverage maps. When the maps are animated, a movie is shown that displays reception of the signal in question. This helps you see in a glance what operating conditions are like during the period you are modeling. In addition, all graphs and circuit analysis results can be animated, to give you a complete picture of what's expected in the model you are displaying.

I've written various columns covering some key propagation topics:

HOW-TO: How do you make your HF ham station work more efficiently? The ANTENNA is the key! - introduction to Antenna Modeling
HOW-TO: Is HF Propagation Reciprocal?
HOW-TO: De-mystifying HF Radio Propagation and Modeling

REVIEW: An Amateur Radio Operator's Review of ACE-HF PRO version 2.06
REVIEW: A Shortwave Listening (SWLing) Review of ACE-HF PRO version 2.06
