Comment on Our Review of the Airspy HF+: Compared against ColibriNANO, Airspy Mini, RSP2 by Max

Airspy HF+ SDR vs ColibriNANO SDR on VHF

Comment on SDRplay Release the RSP1A: A $99 14-bit 1 kHz to 2 GHz Revision of the RSP1 by Juanro

Very improvable design. Minimum 16 bit in ADC. Filters and LNA incorrectly positioned. High noise level, having ultra low noise economic MMIC. The frequency cuts of the filters do not correspond at least with Region 1, and their quality can be improved. The notch filters can also be improved in quality and in frequency, a fourth filter is needed to avoid the annoying LTE of 700/800 Mhz. Cutting frequency in the ideal filters to preserve aeronautical, communications, satellites bands and avoid broadcasting:

0-0.526
0.526-1.607
1.607-14
14-30
30-87.5
87.5-108
108-144
144-174
174-230
230-390
390-470
470-960
960-1710
1710-2000

Hopefully in a few years it will be improved even if it costs a little more.

Airspy HF+ SDR vs ColibriNANO SDR on VHF [00:03:11]

On this video I am comparing The New Airspy HF+ SDR-receiver and ColibriNANO SDR on VHF VOLMET signal (124.325 MHz)
Antenna is Vertical Dipole
In the first part of the video, The signal from antenna is connected directly to antenna input of the receivers. At the second part of the video, the -32 dB external attenuator is connected between the antenna and SDR input.

RTL-SDR Discussion • Re: Can you help me with this? Stick doesn’t detect / work

I got the same error. Did someone get any solution?

Thanks for replying! I also left a note on Github, since I was trying anyway possible to contact you.
At the very least I need any name, date, anything. The no name causes an error for me.
TY!
Jeff

Hi Jeff,
I did as a matter of fact spend some time on that since, because it was bugging me as well. I’ll check and push any changes to GitHub. Stay tuned 🙂

Hi Geo,
I have an issue with your great meteor RPI program.
The attachments that are sent via email have no name.
That is causing a problem in the usage I have in mind.
Is that correct? Or did I do something wrong?
Is there any way toa dd the file name to the attachments?
TY!
Jeff

Receive Noaa and M2 transmissions (NJ/NY area) without antenna and receiver.

I am streaming my 137mhz receiver via Spyserver. You can receive these signals using SDR# and entering my URL:

sdr://k2sdr.dyndns.org:5556/

In SDR# For NOAA use WFM with 40 khz bandwidth. Use WXTOIMG connected via soundcard for NOAA. For Meteor use WFM with 128 khz bandwidth. Use Meteor Demodulator plugin and LRPTAnilizer (AMIGO Version) for decoding/display.

For tracking use New York City or 40.10N -74.01(W)
