Great Product and Exceptional Support

For 10 MHz Oscillator TCXO 10 MHz +/- 0.28 ppm

I purchased this as a clock source for a portable frequency meter / counter. It is small and compact. Runs on USB or a voltage supply between 5 and 10 VDC. Frequency is spot on. I reached out to the seller several times to discuss appropriate techniques to drive a TTL chip. Response was almost immediate and very useful suggestions were offered. I would definitely purchase from GPIO again.

Works very well

For Hydrogen Line Pre-filtered LNA 1420 MHz

Used the LNA 1420 MHz filter with a SAWBird H1+ 1420 MHz LNA and RTL-SDR dongle v3 to detect 21cm neutral hydrogen in our Milky Way galaxy. The results were a far stronger H1 peek! I recommend using this LNA filter.

Very well filter

For 1420 MHz Bandpass Filter Hydrogen Line Radio Astro

The bandpass filter works very well for my hydrogen line measurements at 1420 Mhz. No interferences any more with the very strong 900 Mhz GSM band. Without this filter, very strong signals in the FFT display. It is also very small.

The GPIO Labs HI LNA is perfect for home Radio Astronomy.

For Hydrogen Line Pre-filtered LNA 1420MHz w BIAS TEE

We've purchased 4 of these amplifiers for our array of radio telescopes. With these sensitive amplifiers we can see the Spiral Arms of the Milky Way in a few seconds.

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, i’m sure you can guess which) to help with the same problem.
