Works out of the box. Great piece of kit.
Great piece of kit. Easy to use and loads of support material and videos. At least as of May 25 its a really good buy. Best ham radio thing I bought so far. Supported & designed by a Dutch genius. So pleased with it.

Spectrum Analyser
Works very well for the price. Certainly good for upto 800Mhz calibrated and upto about 12Ghz max. Amazing. Unfortunately have no separate signal generator to test except Bluetooth and Wi-fi signals but appears to pick these up. Reception relies on a reasonable antenna. Antenna supplied works well enough and detects FM broadcasts. The FM demodulator is a great bonus just to hear the broadcast; quality is great for just checking to see what's there. Overall fantastic piece of kit.

3.5mm jack disconnected inside
Overall a great item and everything functioning. However, suddenly, I wasn't able to use the 'Listen' feature because of constant plugging and unplugging of the 3.5mm jack. I unscrewed the back to check the port and it was completely disconnected from the PCB. I had to solder it back on. Just beware that the solder isn't strong enough to hold the 3.5mm jack.

Great bit of kit for the price
Much more affordable than the bigger spectrum analyzers. Great for general use. Don't forget to visit the tinysa website for instructions on enabling ultra mode.
