HackRF One – Probably the Rolls-Royce of Software Defined Radio (SDR) – Even Transmits and is open source hardware

HackRF One from Great Scott Gadgets is a Software Defined Radio peripheral capable of transmission or reception of radio signals from 1 MHz to 6 GHz. Designed to enable test and development of modern and next-generation radio technologies, HackRF One is an open source hardware platform that can be used as a USB peripheral or programmed for stand-alone operation.

It's main features are:
* can receive firmware updates (how many other SDR's do that?)
* 1 MHz to 6 GHz operating frequency
* half-duplex transceiver
* up to 20 million samples per second
* 8-bit quadrature samples (8-bit I and 8-bit Q)
* compatible with GNU Radio, SDR#, and more
* software-configurable RX and TX gain and baseband filter
* software-controlled antenna port power (50 mA at 3.3 V)
* SMA female antenna connector
* SMA female clock input and output for synchronization
* convenient buttons for programming
* internal pin headers for expansion
* Hi-Speed USB 2.0
* USB-powered
* open source hardware
* features various hacks by other owners

It's not cheap at around $299 but if you are really serious about SDR this device will see you into the future.

Opportunity for @telegram to fill the Google+ gap?

Apart from Google+, I also use a few other channels to source and sink curated information to/from the www. The one that's surpassed my expectations by far and could potentially replace G+ for me is Telegram, with a little tweak though.

Telegram launched https://telegra.ph/ not too long ago as a mechanism for publishing content that can then easily be embedded into chats, groups or channels. What would complete the picture for me is a Public Stream of sorts that incorporates posts from the telegra.ph posts of contacts that one follows. It's probably not a big thing to build into Telegram but it's likely something that will turn Telegram into a worthy Google+ replacement.

Telegraph
Telegra.ph is a minimalist publishing tool that allows you to create richly formatted posts and push them to the Web in just a click. Telegraph posts also get beautiful Instant View pages on Telegram.
