Quick video demo of the Tuning option in action, shows multiple VFO's even though the sdrplay is set at 2mhz of bandwidth, you will see as I change VFO, the frequency will be come active, then on some I will move the current VFO frequency, you will see the VFO remains in the current window.

So Alexandru Csete has his LimeSDR working under GQRX on Ubuntu, all the earlybird options on the LimeSDR have been taken, the first 500, now the $299 versions are available on CrowdSupply.

This is going to be an interesting ride, Alex is onboard for GQRX, using the soapysdr package, this also means that Charles Cliffes CubicSDR shhould also work great, this means it should work under windows, and also Simon Brown is now onboard and will build in RX & TX support via SDR-Console V3, and he has already said that if enough suppport, then he may compile to run under V2.3 for RX only.

 

Marty Wittrock KN0CK is also designing an RX/TX amplifier board, to give about 12watts output, so this would make a great QRP SDR Setup.

Lime-SDR, worth it or not, who knows

Update: April 28th: 19:35Z So I went ahead and ordered a LimeSDR, now that i know @G4ELI is getting one, there is more than a good chance that SDR-Console will support the LimeSDR, also with @csete on board too, things are looking better....

 

Update: April28th: 18:23Z : So Alexandru Csete @csete has a LimeSDR and is working on getting it working with GQRX under Linux, We will watch with anticipation and his outcome...

 

Update: Apr28th: So the limesdr launched today, starting at $199 up to $799 if you want the snazzy Aluminum case... hmm, so it seems to me that they are concentrating on the IoT (Internet of Things) market rather than the Ham/SWL market, and Range is supposed to be 100Khz - 3.8Ghz, but there is some internal jiggery pokery to get it running below 30Mhz, so HF might now be as simple as it says? Just a VHF/UHF Device?

They are supported by Concanical (Ubuntu) you would have thought they could have funded the original 500 boards and at least given some to the TOP SDR Programmers like Simon Brown of SDR-Console fame, which is what leads me to the IoT comment, all the videos are about Wifi Nodes etc, I know it's only $199, but that's not cheap for somthing that we don't know even works yet, no proof of the ISS info was ever given...

 

 

Stay Tuned....

 

So tomorrow, April 28th a new SDR Radio launches via Crowd-Supply, the LimeSDR, unknown cost as of writing, also unknown is software usage, nothing has been made available, no reviews, only thing I found was a video/stills of a guy receiving the ISS, with the limeSDR attached to a Raspberry Pi, but no screen shots.

 

 

 

The Radio looks nice, and has great specifications, but so far, as I can tell that's it, no software support when you buy it, you're kind of on your own..

 

So we will see tomorrow what they come up with as far as pricing goes, but it looks like they have missed the BIG opportunity to hit the Amateur/SWL SDR market this radio with its coverage could have been a killer... but now, who knows... I just know I won't be spending my money just yet...

 

It looks like they are targeting the wifi market and building your own connectivity, so we will see...

Not just for geeks - FM Radio

So I don't just listen to Ham's. Sometimes we check out the normal FM band to, to see if we can hear any radio stations from another town, or state... Here we have a simple no-gain wire antenna attached to the SDRPlay and running SDR-Console V3, simon has just added RDS Decode, so you can see the decode from the signal, and you can catch the PI code, this helps identify the station you are listening to, and sometimes the ID that shows up, won't be the call of the station yo uare listening to, like my local WEZL, shows up as KART you can check PI codes at db.wtfda.org enter the PI code (in all caps) and it wil give you the station information.

 

This is WCOS (PI - 1B6E) out of Columbia SC, the TX site is about 125 Miles or so (click to enlarge)

 

Just something else to listen too, it's nice to be able to see the signals as well as hearing them, you may miss some of the weaker stations when you are just scanning through on a regular old type radio, I could get better if I put up a dedicated FM band antenna, but this will do for me for right now... 

 

 

The Elusive VK0EK - Heard Island.

So I spent quite a few hours in between work and caring for my wife Terry, the times i was on the radio I never heard a peep out if them, to me it seems most were low band operations, and my low-band antenna is orientated North/South, so my best signals come from the East/West.

 

I never saw the spotted on the higher bands, one local friend was very lucky and managed to grab them, but I was at work. So I guess this one will be on the Not Worked list for quite a while now. If they had been on 20m and up, we have the gain in the Mosley, so we may have worked them, most dx-peditions park on 14.190-14.200 but never saw it.... oh well, just a country... One day... or a case of Not Heard Island. 

 

One stumbling block, see the mountain in the picture, that's the direction to the East Coast of the USA

 


One of the high band beams, still nothing heard from Heard Island... 

 

SDR-Console V3 Tuning

Someone asked for a quick tuning method for V3, a direct keyboard entry will be added soon, but for now, this is the quickest way....

 

1. Click on the keyboard icon in the bottom right corner

 

2. Change the frequency on the pop up keyboard, using the mouse wheel over the digits you will see the waterfall will change also.

 

3. When on the desired frequency, close the pop up window and click on the waterfall and the frequency will change, unless you are accurate, you may be a few khz off, but this is the quick way until direct entry is enabled.

If you ask why it's difficult for direct entry, we have to decide which vfo is active? Does entering a new frequency move the LO? Does it affect the bandwidth span? Will it move to much to make another VFO/RX inactive? So it's not so simple as a single active VFO/RX? The logic has to be sorted out and that is what Simon is working on.....

As a Radio Amateur and also a Professional broadcaster, this is such a sad sight, to see the end of an era and one of the Voice of America locations closing down, and the destruction of the antenna farm.... sad day for shortwave!
