SO-50 – Amateur Satellite

SO-50 satellite information

SO-50 carries several experiments, including a mode J FM amateur repeater experiment operating on 145.850 MHz uplink and 436.795 MHz downlink. The repeater is available to amateurs worldwide as power permits, using a 67.0 Hertz PL tone on the uplink, for on-demand activation. SO-50 also has a 10 minute timer that must be armed before use. Transmit a 2 second carrier with a PL tone of 74.4 to arm the timer.

The repeater consists of a miniature VHF receiver with sensitivity of -124dBm, having an IF bandwidth of 15 KHz. The receive antenna is a 1/4 wave vertical mounted in the top corner of the spacecraft. The receive audio is filtered and conditioned then gated in the control electronics prior to feeding it to the 250mW UHF transmitter. The downlink antenna is a 1/4 wave mounted in the bottom corner of the spacecraft and canted at 45 degrees inward.

Uniden BC346XT Handheld TrunkTracker III Analog Police Scanner

The Uniden BC346XT is a handheld scanner that’s packed with features. Program up to 9,000 channels or 500 trunked systems in dynamic memory. GPS support gives you location-based scanning, location alerts, and crows-flight navigation with a compatible GPS unit. Fire Tone-Out Alerts you when fire pages are issued, Band Scope gives you a graphic representation of signal activity. Close Call RF Capture tunes to nearby signals with no programming needed, and so much more. Plus, PC programming and control makes setting up the scanner easier than ever.

200 Channel Base Station Scanner Receiver – GRE PSR-200U

The GRE PSR-200U is an affordable scanner with innovative features. You can also receive the FM broadcast band which is an additional capability not found in the previous PSR200 model. Other features include: 200 memories and five pre-programmed bands (Marine, Fire/Police, Air, Amateur and Weather). Plus there are 20 memories just for the FM broadcast band. There is also a built-in priority channel. Another recently added feature is CTCSS decode. The weather capability features SAME technology (with 10 FIPS area memories) and there is a Skywarn function. This radio scans at 40 channel per second and sweeps at 80 steps per second. And you can search Up or Down in either direction. There is also a keypad for direct frequency entry. The large LCD is backlit. This radio supports programming by a PC and unit-to-unit cloning. There is a 3.5 mm earphone jack and BNC external antenna jack on the rear panel. The PSR-200U comes with a screw-in telescopic antenna, AC adapter and manual.

X-Class solar flare sent us a CME? Not this time…

Sunspot AR1598 has erupted again. On Oct. 23rd at 0322 UT, Earth orbiting satellites detected a strong X1-class solar flare but don’t expect anyone to warn of of much more than a lot of the same.  Why create panic for a small possibility of a large impact to our power-grids, radio communications, etc.  I digress, It was spectacular and probably will not change much of anything in your day.  Take a look at this view of it.

October 2012 X-Class Solar Flare -

This flare, however, did not unleash a coronal mass ejection, so it is predicted to cause little disruption on Earth and no special auroras. Its powerful radiation was enough, though, to briefly disrupt radios here last night.X-Class Solar Flare on earth facing side of the sun

GRE PSR-700 Ezscan Radio Scanner w/ Built-In Frequency Database on a 2Gb Hd Mem Crd

Hear all of the action in your area without the complicated programming of frequencies. The GRE PSR-700 EZ Scan-SD is a revolutionary approach to scanner listening. The PSR-700 combines the simplicity and a familiarity of a portable media player with the power and sophistication of a state-of-the-art scanning receiver. It provides unprecedented ease of use, especially for the beginner. The PSR-700 includes a 2GB SD card with a special on-board library containing the entire USA database for all known analog trunking systems and many conventional frequencies. So no matter where you are in the USA, you can easily and instantly access the analog trunking systems and conventional frequencies of interest.
