SDR Limits

From the linked article:
The key feature of the LimeSDR, and all boards derived from Lime Micro’s tech is the LMS7002M. It’s a Field Programmable RF transceiver with coverage from 100kHz to 3.8GHz, a programmable IF filtering from 600kHz to 80MHz, and — this one is important — on-chip reconfigurable ‘signal processing’ and a fast USB 3.0 interface to a computer.

County Comm GP-5/SSB

John reviews the County Comm GP-5/SSB Handheld Receiver (AM, FM, SW, USB, LSB ~1.7 to 30 MHz):
"This is not your typical portable Shortwave radio, but a state of the art SDR with full frequency range and true USB/LSB filters.
Whether your requirements are for EmComm, survival kit, or you're a ham that can't leave his rig behind when on vacation, this impressive handheld receiver is definitely worth considering."
I like the County Comm stuff - I've never bought any of the electronics, but I have purchased several odds and ends.

On the Onion of Ham Radio:
"BaoFeng (the marketing name for PoFung Technologies) has purchased the remaining assets from the holding administrator representing Tokyo High Power Labs." 
"Details are still a little sketchy, but the rumored HF Transceivers are reportedly being labeled:
  • BaoFeng Hurricane (SDR with knobs, 250 watt all band transceiver)
  • BaoFeng Tornado (SDR with knobs, 400 watt all band transceiver)
  • BaoFeng Tsunami (SDR no front panel, 100 watt all band transceiver)"
"We could not verify at this moment, but the suggested retail price for the Tsunami is $180.00 US."

Yaesu FT2DR: Touchscreen HT

So Ford is replacing Microsoft's in-car infotainment platform and replacing it with QNX. Several of the comments to the Slashdot article are complaining about the lack of dedicated knobs and buttons. That complaint echos those I hear from those that don't want to do SDR, because they want knobs and not a mouse.

Makes me wonder what the response will be to the Yaesu FT2DR touchscreen HT. Universal Radio shows a list price of $640, so you know how interested I'll be.

HF-One: HF-One MKII QRP HF Mobile

Thanks to Riku for sending me the link to the HF-One MKII 10 W HF radio. Details are limited, but here is what the listing says you get for your $300 (plus shipping):

- 100K--30MHz rx and tx in all band amateur radio band under 30MHz.
- output max:10W
- mode:ssb /CW
- with SDR
- AUTOKEY build in.
- audio REC build in.




Here is where it gets interesting for me. These images looks like the SDR could be controlled by your iPhone or iPad.





The radio looks very familiar to me. And I'm going to be surprised if there is an app for that - controlling the radio. I've e-mailed the seller to see what else I can find out.

$19 Police Scanner

Definitely about the fun of putting one together, since you can just download an app to your fun - and price should not be a barrier here for most.

Android HT

K0NR ponders about the reality of seeing an Android based HT given the availability of open source software and inexpensive hardware - like in the SDR HTs flooding in from China.

I think this would be a good side project for the folks at Flex Radio. I don't know what the business case would be, but I'd love to see what they could build.
