- 0710Z 11396kHz Jakarta SELCALs many times on LQDM (IDF B738 A-001). It appears this flight departed Jakarta 0230Z and according to FlightRadar24 was last positioned over South East Sulawesi
- 0720Z 11384kHz San Francisco calls Jetstar 24 (Tokyo-Melbourne) and requests they try and contact Indonesian Air Force 2 on guard. A short while later JST24 advises no joy contacting IADF2

- 0639Z 5687kHz Airforce Auckland advises Warrior 07 (RNZAF NH90) that the landing area is a small rugby field in the centre of the township with a steep landing and only one aircraft permitted. This is probably related to the 7.5 magnitude earthquake in the South Island of New Zealand
- 0723Z 5687kHz Warrior 07 calls Airforce Auckland and advises they are just departing Kaikoura with 12 PAX and estimate Christchurch at time 50. Airforce Auckland advises they are now on SELCAL watch

- 0018Z 8867kHz SAM807 calls Auckland with no response. This flight was advised on VHF that at position GULUT contact Auckland on datalink and monitor HF 8867. SAM807 departed Wellington is probably en route Brisbane with Secretary of State John Kerry
- 0334Z 13261kHz QANTAS 27 (Sydney-Santiago) calls Brisbane and advises they are CPDLC and SELCAL code is MQDE (QFA B744 VH-OEG). Brisbane advises primary is 13261 secondary 8867 and the SELCAL check is good
- 0257Z 8867kHz Aussie 211 calls Auckland and reports REPOL 0255 FL360 MOMTA 0349 SELKA next. This is a Boeing P-8 Poseidon probably en route from Honolulu to RNZAF Whenuapai for the RNZN 75th anniversary

- 0904Z 8867kHz Kiwi 265 calls Auckland and reports RUMIX 0404 FL250 LEBOL 0429 SALAG next. Auckland advises they should be calling Nadi on primary 8867 secondary 5643. It never surprises me how the RNZAF get simple things like this wrong. Even looking at skyvector.com it clearly shows who’s airspace you are entering if you are at waypoint RUMIX.
A few days again the courier left me an SDRPlay at the front door!
This rather unassuming looking device packs a decent punch for the princely sum of USD$129 plus shipping, 10kHz – 2GHz!
On opening the package I was quite surprised at how light it felt and in reality it is just a PCB inside a plastic container with a USB port at one end and an SMA antenna connector at the other.
I’m not too sure why I wanted to buy one of these, but I think one of the drawcards was the software that SDRPlay provides for driving this little receiver. SDRuno is a version of that very costly Studio 1 product but having bought the rights from the owner SDRPlay now provides this free, and not just for the SDRPlay RSP1! I had been using the software with my v3 RTL-SDR and also with my Elad FDM-S2 and really, I quite like its GUI.
I had read a fair bit about the noise this receiver allows to creep into its insides but frankly, I’ve not had an ounce of problems despite using a USB cable with no ferrite chokes and sitting next to a desktop PC and two LCD monitors.
As for performance, it’s not got as low a noise floor as the Elad but that can only be expected for the cost. On one evening last week I was picking up aircraft over the Bay of Biscay talking to Santa Maria and as of yet I have been hearing all the stations that my Elad hears using the SDRPlay. The SDRuno software has sufficient flexibility to reduce noise, change gain settings but the one lacking feature is the ability to draw out the signal on the waterfall display visually. This makes me sometimes think that the signals just breaking contrast are too weak to hear but when tuning to the signal it is perfectly audible and adjusting the AF bandwidth I can make it a pleasant receiver to listen to HF signals with.
One very good feature of this is the wideband settings of between 500kHz and 8MHz. Mostly I find 2MHz sufficient on HF and this saves me having to adjust the local oscillator too often when browsing the more wider of the HF bands.
Of course there are the VHF airband signals as well, which was another reason I thought I might like it and testing with a poorly made homebrew antenna has shown much promise. This is where the 8MHz bandwidth comes in real handy!Read More
