Tried a very cheap transceiver

In MTB and backcountry skiing, we often need to check each other's location, but sometimes cell phones are out of service area or the act of making a call is troublesome.
A full-fledged radio would be best, but you need a license to begin with and things are not cheap.
So I came up with the idea of a specified low-power transceiver, which was popular in the past, and bought one from Amazon.
It is a very cheap product.

昔に流行った物ですが、携帯電話に頼らず簡単に合図を送ったり確認する手段としては安い、免許不要でかなり良かったです。
シビアな性能を求めてはだめですが、グループ内で持っていると全然違いました
