W3EEE on LF radio..

January 13, 2010 | Amateur Radio | By: Mark VandeWettering

It’s too late, I should be in bed, but once again I’m reading up on low frequency radio communication, another of those oddball interests you pick up when you read too much. I blame tuning around with the SDR-IQ this evening, where I found that a number of DGPS beacons were easily heard down around 314Khz. Trying to find more information lead me to W3EEE’s excellent LF website, which makes me think that perhaps I should try receiving NAVTEX beacons sometime. Good stuff.

Hello Mark,

Not directly related, but wanted to thank you for your website. I just found it recently via a mention on soldersmoke. There is indeed endless stuff to explore in this world, and your site adds to my workload – er I mean enjoyment! Now you’d added LF to the list.

FYI, I’ve been working on control systems for largish (1-4m class) telescopes for much of my career as an EE. I developed XEphem along the way, see http://www.xephem.com . Have been a ham since 1974 but activity levels have varied greatly over the years. Lately I’m keen on QRP and, of all things, improving my CW skills, sort of a nod to nostalgia I guess. Now I use touchless paddles from http://www.cwtouchkeyer.com (shameless plug, I think they’re great).

Anyway, thanks for taking the time to post all the various leads and topics you get into, they’re great fodder for more fiddling and learning.

PS: I visited the Pixar facility way back in 1986. I was working on a medical imaging application and we were looking for new ways of rendering CT and MR data in 3D. We ended up making our own custom rendering engine with a few dozen “bit slice” processors and using voxel techniques but I have a fond memory of seeing Pixar at a fairly infant stage.

hi Mark-

Stopping by agn… ref NavTex.

Have you tried the multi-mode digi program “MultiPsk” de F6CTE. The layout is a little busy- like that of a 747 cockpit. hi But fun.

I’ll send you a rcv’d NavTex pic decoded in MultiPsk on 517khz.
