but only two are in the ham bands. The rest are a collection of airband, marine, FEMA, search and rescue, National Guard, US Air Force, etc. Most of these frequencies are not legal for the general public to use. An FCC amateur radio license...
NOAA weather stations usually have ham radio operators and equipment on board at you local weather station to monitor the "spotter ham radio frequencies" so they can get the severe weather reports out to the public much faster. Many "eyes" on the ground are much better than radar in many c...
near real-time sounding readings (in MHz) from Boulder CO USA, Athens Greece, Hermanus South Africa, Sondrestrom Greenland, King Salmon Alaska USA, Niue Island, Darwin Australia, Tromso Norway, Ascension Island, Mawson Antarctica, and Jicamarca Peru all plotted on a near real-time sunlit map....
I have made a number of Lindenblads over the last few years, designed for various frequencies, and particularly like their simplicity, robustness and effectiveness for LEO satellite communications. They may not be the ultimate NOAA 137MHz antenna, but they’re pretty damn good in my opinion. If...
Finally on to the studs that hold the instrument panel on. They are long so I had to invest in some nut drivers that had hollow shafts that would allow them to get to the nut. There is almost no room under that dash to get at the studs, especially from straight on. It took me da...
Under theFrequencies tab– if you find there are no frequencies listed for the different modes, position cursor in the Working Frequencies window and right click and select ‘Reset’. This should populate the window with all the frequencies. ...
That part remained true until about ten years ago – but especially five years ago when we moved from our beachfront condo on Sand Key Island near Clearwater Beach, Florida where we had lived for eight years before moving to our current home inPotomac, Maryland– 15 miles from theWhite Hous...
WeRebuild have even set upan IRC channel for ham operators monitoring these frequencies. TheHuffington Postquotes some of the messages. As I write this there are 91 posts ina discussion thread on QRZ.comdebating the use of ham radio by the protesters and overseas operators. Amongst the majorit...
On September 11th, the A index jumped to 21 and the next day it went to 35 as a result of a geomagnetic storm caused byCoronal Hole High Speed Streams (CH HSS). Frequencies 20 meters and higher were affected so everyone was crammed on the low bands. ...
Since my build, I I made a mod in order to give me not two, but three selectable frequencies. I added an octal tube socket to the left side of the cigar box and installed another DPDT toggle switch. The octal socket will accommodate two FT243 crystals so by wiring per my diagram belo...
