Friday Night 60-Meteers APRS Tests with "UI-Microserver"


Starting at 9:00 PM Friday evening US Eastern time (0100 UTC Saturday morning), I will be testing again on 60-meters APRS.

As before, I will be operating on US "Channel 5" (5403.50 KHz USB). 

The new twist this time is my new "UI-MicroWebserver/Igate".   I have cram-fitted two copies of UIview, APRS Messenger and the UZ7HO Soundmodem into a USD $65 7-inch Windows 8.1 tablet.  This device has a whopping 16GB of flash memory (That's the OS and applications and data!) and a total of 1 GB of RAM. See review of this device here on my website at

Note that this is different from the usual "WA8LMF Special Events APRS Webserver" you may have accessed in the past.  If this works successfully, I can radically cut the power consumption of the web server.  The normal spec events server is running on a Lenovo M57 low-profile desktop PC and consumes about 45 watts.    The tablet-based "Micro-Server draws only 2.9 watts.

Further, the tablet is easily powered by a 12VDC power source via a standard lighter-jack 5VDC cellphone/iPad charger.  The total drain is only .25 amps at 13.8 VDC, making the device ideal for temporary in-the-field igate/digipeater operations in a car.

Here is a quick-and-dirty snapshot of the tablet, the Behringer UCA202 USB sound card, and the TS-2000 it's hooked up to.
