A $1 range tester for VHF/UHF handheld transceivers
Grab just 4 components and build a range tester for a VHF/UHF handheld transceiver.
You'll be able to walk or drive around and have instant feedback on if your mobile signal is being received at home or in a car.
Don't be afraid to experiment with values for the resistor and capacitor if it doesn't trigger with your transceiver or you want to alter the timing. Eg the 1k resistor can be as high as 10k and the 10 uF can be as high as 100 uF.

QUANS
quansheng-uv-k5-top-3-hf-receiving-tips
When loaded with suitable firmware the Quansheng UV-K5 can receive HF signals down to about 17 MHz. However performance can be lacking if you don't pay attention to antennas, filtering and settings. Here's three tips that will help you get great HF reception from this amazing radio.
Purchase your own UV-K5 via eBay here: https://ebay.us/Ca4YzA
IJV firmware (latest is v3.13). More here: https://www.universirius.com/en_gb/pr...

AMPLI
amplified-crystal-set-tunes-hf-amateurs
An amplified crystal set receiving amateur activity on 80 metres.
There's nothing special about the circuit - it's just a normal crystal set with an airwound coil covering 3.5 MHz. Audio is fed to a 1 transistor amplifier - again a common circuit - to drive a crystal earphone.
The main point of this demonstration is the effect of the 3.5 MHz beat frequency oscillator (previously featured on this channel). It provides some RF bias to the diode. This improves its weak signal performance and allows reception of CW/SSB signals.
Hence it's effectively a direct conversion receiver. However the gain seems to be a touch higher - almost all very simple DC receivers have at least a two transistor audio amplifier, whereas this uses just one.
Note that you do need a good antenna to get good results on this or any crystal set-type circuit. If it's not resonant an antenna coupling unit is essential - without one you'll hear nothing.
Part 2 follows.
