AA6E Station Log: Fun with WSJT-X

http://blog.aa6e.net/2014/07/fun-with-wsjt-x.html

Notes from an Amateur Radio operator. AA6E's "static" web site. Monday, July 21, 2014. Since this weekend's ARRL 100th Convention, I've been trying out WSJT-X. The latest from Joe Taylor K1JT in his series of "Weak Signal" programs. It supports the JT65 and JT9 digital modes, mainly for HF communications (1.8 - 30 MHz). It's a more modern and user-friendly program than the original WSJT. Subscribe to: Post Comments (Atom). Martin Ewing ( www.aa6e.net. Branford, Connecticut, USA. Access by Topic (label).

AA6E Station Log: Internet Speed Tests

http://blog.aa6e.net/2014/04/internet-speed-tests.html

Notes from an Amateur Radio operator. AA6E's "static" web site. Sunday, April 27, 2014. At AA6E, we are using the Comcast. Xfinity" "blast" service, which originally provided 50 Mb/s download, but now seems to have been quietly upgraded to 100 Mb/s. Oh, we seem to have IPv6. Service now, too. Effectively using that. In my home network will be a challenge. (One that I don't need at this time! Test with http:/ speedtest.comcast.net. But Boston is not. Subscribe to: Post Comments (Atom).

AA6E Station Log: September 2014

http://blog.aa6e.net/2014_09_01_archive.html

Notes from an Amateur Radio operator. AA6E's "static" web site. Monday, September 29, 2014. Matt and Andrew from XX Towers. Stopped by to repair the latest problem with my 3-element SteppIR. After a recent storm, I discovered high-ish (2.2) SWR on the lower bands and approximately 0 dB Front-to-Back ratio. Effectively, I had a so-so rotatable dipole. (Still, it was fine for many contacts with JT65. Sometimes directivity is over-rated! Links to this post. Subscribe to: Posts (Atom). Access by Topic (label).

AA6E Station Log: January 2015

http://blog.aa6e.net/2015_01_01_archive.html

Notes from an Amateur Radio operator. AA6E's "static" web site. Wednesday, January 14, 2015. FlexControl for Linux #hamr. Lately I've been on the air with a FLEX-6700 from FlexRadio Systems. It's a great rig, but that's a story for another day. Today's subject is the beautiful FlexControl. So that's fine, but I'm mainly a Linux guy. For unfortunate but understandable reasons, Flex only provides Windows control software. What does the FlexControl look like when plugged into a Linux system? You can set up ...

AA6E Station Log: Radio Warmup Issues

http://blog.aa6e.net/2014/08/radio-warmup-issues.html

Notes from an Amateur Radio operator. AA6E's "static" web site. Friday, August 15, 2014. Software has various uses. One neat one is to measure frequencies and drifts accurately. This is the warmup curve for the TenTec. Is this result good or bad? Clearly, we are in spec at this particular operating temperature, but in fact the specification does not really tell us what to expect in terms of accuracy or stability at any particular ambient temperature. Some newer rigs are better. For example, the Flex.

Notes from an Amateur Radio operator. AA6E's "static" web site. Wednesday, May 14, 2014. Tiny Python Panadapter (QST 4/2014). This posting refers to my QST magazine article, "A Tiny Python Panadapter". April, 2014, pp 33-38. For latest information, see my website. The code repository and a support mailing list are available at SourceForge.net. Message from Gary KM5TY:. Would the python code be a bottle neck for the data? Limited CPU power of the tiny cards. The USB soundcards and the RPi/BBB are commodit...
