Kirisun S780: Update

Some more info on the Kirisun S780.

I watched the following video at Han's place.



I also found (surprise!) a Yahoo Group for the S780.

Which then lead me to this most excellent blog - http://radiosification.blogspot.com:

"This blog will be closely linked with my YouTube account and will feature similar themes. I aim to cover topics to do with radio including the use of scanners; software defined radio; PMR446; UHF and VHF radio; amateur radio; shortwave listening; digital modes such as DMR, dPMR, NXDN, TETRA, maybe even D-STAR, and decoding some of these modes."

Which, of course, turns out to be the same person that did the video. He's got a lot of good info on the S780. I've added him to my RSS feed.

Watching and reading all the stuff above has me even more interested in the S780 - despite it being outside my normal price range.

Chromecast

Chromecast - a $35 (plus shipping/tax) HDMI dongle for streaming video to your TV. It will stream from Chrome, Youtube, and Netflix. They same more to come - Amazon maybe? You can control it from a PC or tablet. Buy now and you get 3 months of Netflix free. I have a Wii for Netflix in our living room, but the TV in our bedroom isn't connected at all.

I'm in for one.

harrymccracken Now Google’s unveiling Chromecast, a tiny HD-streaming gizmo you plug into a TV’s HDMI. Yup, another Google approach to Net-enabling TVs. Wed, Jul 24 12:51:50 from Tweetbot for iOS

Word of the Day

Malaise.

Must Have Feature

My wife's car is in for service. I'm driving a seven year newer version of her car as a loaner. It has lots of fancy features - rear camera, radio mutes when the car is in reverse, a button to engage the parking brake, etc. Of all the changes, the one thing I wish I had the most - the cup holders. The cup holder in our car is horrible - basically unusable.

I have found the source of some of the cheap radios - the US Marshals.
