Run this on all of my general SDRs

For FM Notch Filter 88-108MHz Optimized for Airband

I have the wonderful misfortune of living a few KM from the Sky Tower in Auckland, which is a very tall, high power FM broadcast transmitter, amongst many other things.

This filter helps no end with the massive FM overload I get and therefore has a permanent home on each of my SDRs. I have also used it on a HT with less than favourable filtering/selectivity (RX only, iā€™m sure you can guess which) to help with the same problem.

Excellent product & vendor

For Low Noise Amplifier 10-3000MHz; Gain>20dB w/ ESD

I'm using this product for SDR experiments and it works great. The board is also nicely made. This vendor is very responsive via email.

Exactly as described and worked perfectly.

For Mini-circuits LTCC filter design kit (LFCN HFCN)

The circuit boards were exactly as described and of excellent quality. I was able to solder my SMT components without any difficulty. My only issue was the delivery time. I ordered on June 17 and didn't receive my order until July 1st. I highly recommend the circuit boards unless you need them in a hurry.

Recommended : removes FM and harmonics

For FM Notch Filter 88-108MHz ; SMA-M + SMA-F

Removes FM and harmonics with no detectable changes to signals outside the notch.

Nice small form factor as a bonus.

Recommended

For Low Noise Amplifier 10-3000MHz; Gain>20dB w/ ESD

Just arrived, and I compared against a vanilla SPF5189Z. This is cleaner with a better noise floor with good gain. Nice compact PCB, executed cleanly with some useful features like a USB power connection and LED power indicator. The ESD protection is appreciated, too. The folks at gpio are friendly and responsive.

Excelent

For AIS Receive Band Pass Filter at 162 MHz

Excelent Product and delivery. This product is necessary for our research in our department of the university.

Astonishing results from city center / 1st floor

For Ultra LNA 0.01-2GHz Gain >20dB NF 0.5 w USB cable

This changed everything for a default antenna put on the balcony of a 1st floor appartment in a city center block (averages 7 floors, very busy area).

Before using this LNA my RTL-SDR detected at most 10 flight beacons with dump1090, now I get at least 50 beacons almost immediately!

I wasn't expecting that much changes, this totally exceeded my expectations :-)

Great product!

For FM Notch Filter 88-108MHz; Airband applications

Great FM Notch Filter performance with my RTL-SDR (V3) dongle. Using it in front of their Ultra Low Noise Amplifier.

Thanks a ton GPIO for shipping this on the other side of the globe. Packaging was great!

Worked great with my RTL-SDR dongle

For Ultra Low Noise Amplifier 10 MHz to 4000 MHz

Great pre-amp performance with my RTL-SDR (V3) dongle. Didn't expected this much efficiency from this little LNA.

If you're from a noisy environment (like me) then I would suggest to use their FM Notch Filter. Also you may have to tweak the LNA gain from 'input controls' (I'm using GQRX) in case you're input is saturated.

Thanks a ton GPIO for shipping this on the other side of the globe. Packaging was great!

Very good quality RF adapter

For SMA Male to SMA Male Plug RF Adapter Straight Gold

Quality is really good. Using it with my setup of RTL-SDR (V3) dongle + FM Notch Filter + LNA.
Thanks a lot GPIO for shipping this on time. Great packaging!

Great Product, Fantastic Seller

For Low Noise Amplifier 10-6000MHz 40dB Gain, 0.8dB NF

I ordered 4 products from GPIO: two different LNAs, the 315 MHz Bandpass and the FM Notch. All products work excellent. I found that using the filters before the LNA work best with the RTL-SDR dongles. Also, the seller was great to work with. I made a mistake with my shipping address, and GPIO was quickly able to help me figure out who to contact to get the package before it was sent back. I highly recommend GPIO and will definitely use them in the future.

915 MHz ISM Band Pass filter

For 915 MHz ISM Band Pass filter; Amateur Radio RFID

It works great. And it's powered by USB. I strong recommend this band pass filter - as well as the 433 MHz and 2.4 GHz band pass filters. I have several them and I use them on a HackRF and RTL dongle.
