Part-5 guys: Will you keep your Part-5 grant after the Part-97 implementation?

– Posted in: 630 Meter General Topics, 630 Meters

I'm trying to work through this question myself...On one hand, maintaining the Part-5 grant could potentially give me some flexibility for doing experiments that I might not have under Part-97 rules, including portability and increased ERP (currently granted 10W ERP max).  For me, the XIQ call sign is also nostalgic. I suppose the complication for [...]

Don’t wait! Initial comment period for ET 15-99 ends August 31

– Posted in: 630 Meter General Topics, 630 Meters

Its seems like an eternity since comments began posting on the NPRM to create a 630-meter band under Part-97, and almost equally long since the comment period formally opened with the publication of the proceeding in the Federal Register almost 60 days ago. Its particularly important for stations that are actually operating on 630-meters now [...]

Signals that just can’t move north – a textbook case of signal behavior when the K – index is elevated

– Posted in: 630 Meter General Topics, 630 Meters

On a number of occasions I have commented about southern-originating signals that struggle to move north during periods of elevated geomagnetic activity.  I get a lot of blank stares when I say this as it is obviously not clear what I mean.  Last night, only a few hours after full dark here in North Texas, [...]

Hamcom 2016 – MF and LF Symposium?

– Posted in: 630 Meter General Topics, 630 Meters

In response to the very positive comments about this year's 630-meter discussion panel at Hamcom with guests Eric Tichansky and John Molnar, I am thinking about hosting a number of sessions at Hamcom 2016 and utilizing the same remote access applications as I did this year in order to bring in talented and experience operators [...]

FCC files NPRM for 630-meters and 2200-meters!

– Posted in: 630 Meter General Topics, 630 Meters

The day has finally come and I think it took many of us by surprise - The FCC announces the NPRM for and MF and LF amateur allocation. The NPRM can be read at:  http://www.fcc.gov/document/implementation-world-radiocommunication-conferences-wrc-07-wrc-12  .  Note that the contents are not terribly user-friendly but lawyers might enjoy it. So what does this mean?  Well, [...]

VLF birds!

– Posted in: 630 Meter General Topics, 630 Meters

No, its not a new game for your IPhone! Its not even really related to the 630-meter band but its very cool nonetheless. This recording is long, maybe 9-minutes, and there is no real reason to listen to all of it unless you just want to. Hear the birds singing?  There is no microphone!  This [...]

Why I choose to use WSPR

– Posted in: 630 Meter General Topics, 630 Meters

A lot of ops ask, “Why do you insist on running WSPR2 when there are modes with better detection limits?”  Still others ask how I could possibly run anything except CW on the hallowed maritime bands.  You really can’t please most people most of the time but I will attempt to very briefly justify my [...]

“What I have sorta been working on recently” or “The project that has been on the back burner for far too long”

– Posted in: 630 Meter General Topics, 630 Meters

Take your pick on the title as they are both accurate.  What the titles do not imply is just how important this little project is. For some time now I have been talking about wanting to go camping and operating 630m portable.  I thought a good start would be car camping at Cedar Hill State [...]

Why 630-meters?

– Posted in: 630 Meter General Topics, 630 Meters

John Langridge KB5NJD / WG2XIQ I am often asked, “Why do you operate on 630-meters when there are easier ways to communicate?” I would expect a question like this from a non-ham, layman, or I-phone carrying teenager but more and more I find licensed amateurs asking that question. In all cases that I have encountered, [...]
