I have had my Airspy + HF since the pre order from when first came out. I have never done any updates. I mostly just use as a scope. Any real value of updating for what I use it for. Is there a step

Define 'Golden'. I wouldn't want to use such an antenna with an HF+ Discovery. The HF+ Discovery covers zero to 31MHz and 60 to 260MHz. -- Brian Gregory. bdgregory@... www.Brian-Gregory.me.uk

When I was young (a few decades ago...) the guru of the local ham community preached to use as coax cable for the antennas, also for transmitting, the RG-11 instead of the RG-8.

A discone that covers down to 10 MHz is mighty large! Possible that should read 100 MHz through 1300 MHz? Dave - WØLEV -- Dave - WØLEV Just Let Darwin Work Just Think

This version is already rolled and working in the field. If your flash failed, erase the unit and try again.

When I tried to run the software airspy-fmradion 0.6.10-pre0 at https://github.com/jj1bdx/airspy-fmradion/tree/v0.6.10-pre0 on the Firmware R2.2.0-BB, the software failed to initialize Airspy HF+ (old

Hi Are we still talking about hf+ if so just use what ever youhave-the noise at hf dominates!!!. Hardy Fra:main@airspy.groups.io [mailto:main@airspy.groups.io] På vegne af KennethSejkora via

Hello Duke, If possible, get the lowest-loss cable you can, within reason. Cable loss increases with frequency, so if you plan on doing most of your listening in the upper VHF and UHF region, cable

Did you read the specifications for the AirSpy HF+ Discovery? {o.o}

Greetings, Purchased the Pre-order HF+Discovery. Went to purchase an Antenna from site and they are back-ordered. Have been looking at the Discone antennas with the wip. Says from 10Mhz ~ 1300. that

I just typed in ./gqrx -e Then changed the Device from Complex Sampled to HF+. Thanks to whoever provided the instructional video.

That's really pushing the spec limits. Try decimation or a lower MSPS. I'm surprised it worked on XP at all. That's not a supported OS anymore. Joe M.

Hi there Has AnyOne succeseded to get the AirSpy working on Dell E6410 ATG or any other PC with Intel QM57 Chipset running windows XP ? When I test the AirSpy with the AirSpy_rx Util i get

I found this statement in GQRX in Linux, when I open Configure I/O devices, I/Q input, Device string: file=/path/to/your/file,freq=100e6,rate=1e6,repeat=true,throttle=true /path/to/your/file: No such

I'm very confused by your bandwidth comments here. I don't know much about SDR#, but if it shows a couple of MHz around the notional line frequency of 1420.40575MHz, and allows deep

That hump is likely the hydrogen line signal. What size is your horn antenna? NRAO has a fairly full collection of tutorials on basic radio astronomy, including discussions of

1) What is the aperture of your horn? 2) How much gain do you have after the two LNA4ALL preamps? 3) What is the loss of your BPF for 1420? 4) What is you detection bandwidth? 5) What is the

I have the Airspy Mini and I have built a horn antenna, I'm using 2 LNA4ALLs and a 1420-1470 MHz bandpass filter in between them. I think I have picked up the hydrogen emission signal. I would like to

I realize you posted this over 2 years ago but I'm doing some radio astronomy with Astro Spy and a small homebuilt horn antenna. I would love to compare your screen shots with mine if you still have
