Small Wi-Fi Routers

I can imagine some instances where you want to quickly set up a WLAN consisting of a few Raspberry Pi.  Internet access would not necessarily be a requirement but using DHCP to hand out a few addresses would be.  Has anyone had good luck with a small wireless router ?  Ideally the administrator screen would play well with mobile devices ex: an iphone or ipad.  Then after I see the RPis are working, I could log out and leave it along until it was time to disassemble the demonstration.    -- Scott KD5NJR

Raspberry Pi 2 Breakthrough!

For those of you that are interested, the Raspberry Pi foundation has formally announced the Raspberry Pi 2.  It is a quad core next generation ARM processor machine with six times the speed and twice the memory.


And there is even talk about Windows 10 running on it.


For those applications (primarily DSP) that were borderline to run on the Pi, this may be the breakthrough that brings them on board.


By the way, all of this is at the same retail price of $35.

Hands-on FLDIGI Training February 7th OKC

For Immediate release

The communications software FLDIGI training is set to be offered February 7 from noon to 6 p.m. at the Oklahoma City Police and Fire Academy, 850 North Portland Avenue, in Oklahoma City, according to Jeff Scoville, AE5ME, instructor for the class.

The training is free and is sponsored by the Tulsa Digital Radio Club.

"Fldigi is a computer program intended for Amateur Radio Digital Modes operation using a PC (Personal Computer). Fldigi operates (as does most similar software) in conjunction with a conventional High Frequency Single Sideband radio transceiver, and uses the PC sound card as the main means of input from the radio, and output to the radio. These are audio-frequency signals. The software also controls the radio by means of another connection, typically a serial port." 

According to Stan Bradley, KS5B, the training will also be available through the services of the Tuttle First Baptist Church video streaming service..  "Look for the FLDIGI icon after connecting"

For more information, one may contact Jeff, AE5ME regarding FLDIGI and Stan, KS5B regarding the training feed.

More success from AE5QL Soft Rock + Amplifier kit!

First of all, Happy New Year to everyone.  Looking forward to lots of neat stuff in the coming 2015 year!

Looks like Mike AE5QL is already having quite a good time with his SoftRock receiver and transmitter and a 30 watt amplifier that he built to go along with it:

Tonight I have made my first contacts using my Softrock RX/TX and my EB63A amp. I am running about 3/4 output on the Softrock to achieve about 30 watts on the EB63A on 40 Meters, (7.070 +300 Hz to 1800 Hz showing on FLDIGI. The signal looks good on the O-Scope and nobody has complained so I hope things are working well. The contacts are from the East Coast, New York, North Carolina and Florida.

I had to tune the carrier operated relay (COR) circuit, it was way too sensitive, It now works well with digital, it may require more tuning to get the SSB phone working as well.
