NooElecNooElec SAWbird+ NOAA - Premium Saw Filter & Cascaded Ultra-Low Noise LNA Module for NOAA Applications. 137MHz Center Frequency

Product arrived as promised and works as specified.

It reduces FM radio and air band around 10dB, and now I can receives good NOAA images under 30 degree elevations which is impossible before I install this LNA!

Bad news first: (1) It's too darn expensive for the minimal amount of use I get from it. (2) The extra gain that it provides over their non-sawbird LNA, wasn't worth it to me.Good news: (1) True filtering, it really cleans up the segment it is designed for. (2) Although not superb amounts of gain, if you're serious about this frequency segment, get this LNA, it works.Honestly, the reason for the 4 stars is the price. Would I buy it again, not this frequency segment, but I am not dead set against purchasing one of their other sawbird+ LNA's.

Make sure you install this in the right direction. It isn’t obvious. The white light will go on when it is installed in the right direction.SDR sharp shows significant increase in gain and the images come through very crisp. I use this with RTL SDRv3 and enables bias tee using their Windows application. If using with SDR#, close SDR# before launching rtl_biast.exe. You will probably have to change the device ID from 0 to 1 like I did. If it works then you will get Found Rafael... message then the program quits. Plug in the LNA and the light should turn on. That’s it.

Good for 136-139 MHz. Good signal from Meteor M2-3, my QFH syncs when it’s 5 degrees above horizon.

I had another companies wide-band , unfiltered LNA working. I bought this hoping that perhaps some of the noise in my images might bet filtered out. It works. but produced images of less quality than my other LNA. I probably don't have a problem with nearby AM or FM stations and when I use filters my images just get noisier because the signal is weakened. The SAWbird also caused my RTL-SDR dongle to get too hot. I could fix that by clipping a sheet of foil onto it as a heat radiator. I am using a horizontal V dipole, perhaps this would work better for some urban dweller and or a QFH-type antenna.

I have this installed on my roof (inside a waterproof box). It's been running all summer in pretty extreme heat with no problems. I have it hooked to a Raspberry Pi, RTL-SDR and QFH antenna for receiving NOAA / METEOR weather satellite images. I would definitely buy this again.

Used for NOAA APT reception at 137MHz

Low-noise amplifier with the filtering lower-cost SDRs need for best results. Nicely packaged.

excelente desempeño y precio. gracias

This filter has a feel of quality about it and it has helped improve the NOAA weather images I can receive using a simple horizontal V aerial. Works best with the filter located at the aerial and powered by a biased T.

Der Stick liefert hervorragende Satellitenbilder. Gleich beim ersten Versuch kam ein hervorragendes Bild mit dem Nooelec v5 und einer Albrecht 1300 Desktopantenne. Zusätzlich wird ebenfalls ein Adapter mitgeliefert, inklusive Stromkabel für die externe Stromversorgung. Jedoch ist das externe Kabel nicht vollständig. Man benötigt einen extra Adapter für die Steckdose oder USB. Das Gerät selber fühlt sich durch das Metallgehäuse sehr wertig an. Input/Output sind für den Laien deutlich markiert. Wenn man NOAA Bilder (oder ähnliche APT Bilder) empfangen möchte, ist man hier bei dem vermutlich besten Gerät auf dem Markt bestens beraten.Pro:- Sehr gute Empfangsverbesserung- Angemessener Preis- Eindeutig beschriftet- Zusatzadapter mit LadeadapterKontra:- Für externe Stromversorgung wird ein Steckdosenadapter bis 5,2V benötigt- Stromversorgung zwingend erforderlich

Bon produit pour clef sdr.pour un sdr genre sdrplay pas necessaire.
