Re: Suitable SDR hardware for HFDL
Mike, The USAF transport aircraft are regularly on L band but rarely on C band, never seen any positional data for them as they cross the Atlantic Cheers, Paul On Tue, 13 Nov 2018, 20:43 MadMike <virtualtrains@... wrote:

Re: Suitable SDR hardware for HFDL

Hi Paul, I agree with Dick, there are a very few USAF aircraft on HFDL on trans-Pacific routes, but the number seems to be reducing all the time, so possibly on C-Band/L-Band now.

Dear All,To the best of my knowledge, the only way to find a transmitter is with a directional antenna and some type of signal strength indicator--what in US Amateur Radio circles is called a "bunny hunt." It also depends on the length of the transmission. If it only occurs sporadically and of short duration, it will be much more difficult to find. The Federal Communications Commission has some very sophisticated direction finding equipment, but they still have to follow this routine to catch illegal transmissions. (They are also severely underfunded, so it is hard to get them out to locate illegal transmitters, altho when they do, the fines are truly punitive--typically in the $10,000 range!) doug, WA2SAY, retired RF engineer |

Re: Suitable SDR hardware for HFDL
Hi
Dick,
Not
looking very hopeful for me, I have monitored L band in the past and as you say
plenty of USAF mil traffic, thats why I was expecting to see them on C-band, but
no luck so far.
Unfortunately
until I get more equipment I cannot receive both L band and C band at the same
time so I'm not monitoring L band at the moment.
Time
will tell.
Cheers,
Paul On

Re: Lime Transmit
Excellent! I have a LimeSDR, GPIO board for it and the LMS-8001a Companion Board. Ready to test when you are!

Dear All, Good Day, I want ask about if there is any way to locate the transmitter location or defined the transmitter by code or any way to know who is transmitting now over VHF 2 meter . I am using Icom ID-5100 , Airspy HF+ & NESDR SMART NOOELEC. tHANKS |

Re: Suitable SDR hardware for HFDL

Hi Paul,
My November-12 log shows 4534 messages logged on 8942 KHz (Shannon) between 09:02:06 UTC and 17:00:15 UTC. It contains 1588 coordinates. USAF aircraft are rare on HFDL. Logging just one frequency (8942 KHz Shannon) and searching for ICAO AE revealed these for this month: ICAO AE025D ICAO AE0140 ICAO AE0560 ICAO AE0803 ICAO AE013D
Searching for Flight ID = MC revealed only 2 records for this month: November06.txt:08:22:26 UTC Flight ID = MC0003 LAT 41 43 47 N LON 33 27 46 E November06.txt:10:30:36 UTC Flight ID = MC0003 LAT 40 41 54 N LON 13 14 11 E This was ICAO AE0560 using Reg: 50003B ~ 85-0003 Lockheed C-5B Galaxy
I did log quite a few AE.... on L-Band when I was playing with JAERO in June this year.
Cheers, Dick

Re: Lime Transmit
USB 2.0 should be OK for 5MHz bandwidth. On TX I drive at 3.072MHz.

Hi,
I’m tidying up a few things, today I hope to get the TX Spur reduced further. I will ask Lime owners to join the test team for initial testing. Myself I’m using the Lime on TX and Airspy HF+ for monitoring the output.
So, even if not kit today I do hope to have a kit tomorrow.

is the TX support for the LimeSDR (USB not Mini) ready and publicly available?
Many thanks in advance for your answer.

OK,
With 8v from a PSU it’s transmitting much better, now I must tune the software which will take a day or two.

Re: Suitable SDR hardware for HFDL
Hi
Mike,
Thanks
for that info, disappointing - do you ever see any Military traffic on HFDL? I
was hoping to plot the USAF transport aircraft across the Atlantic (C17's and
KC135's - I haven't found either on C-band yet)
I'll
give it a go and see what I can find, a learning curve if nothing else :)

Re: BladeRF
Hi,
If you’re using the latest firmware then very probably you must use the bladeRF2 support, I doubt the old library (bladeRF) will support newer firmware. In the future this is the support library that will be supported.
I can’t really give any suggestions for the transverter I’m afraid, I have never tried it. If features are missing let me know.
Hoping to have TX support this year ready for the Es’Hail 2 satellite.

Hi I have a bladeRF X115 and XB200 transverter and am having a few problems. On a Windows 7 / 64Bit workstation I can connect to the bladeRF via the bladeCLi application all good, and I have loaded the latest FPGA image etc. When using SDR Console v3, I can only connect to the bladeRF using bladeRF2 in the radio settings section. Is this correct ? Secondly how do I set up the HF transverter in SDR Console v3 ? Any advice about gain & settings ? Finally on the same workstation, SDR Console v2 didn't connect at all to the bladeRF I have. Thanks to Simon for such a great piece of software! Adrian Rees M1LCR
