I don’t use this cheap handheld often, on the contrary, I rarely use it.
\nAnyway, I prepared it for the holiday trip, to hear some local Hams and have FM chat.
\nOnce I got there I turned on the small radio and with great surprise I could not hook up any repeater, even the FM broadcast band was quiet or with very low signals. Then, moving the antenna, I realized that this had something wrong.
\nSo I spent the holidays between the pool and the sea leaving the radio in a drawer.
\nOnce at home I dismantled the antenna and with (little) surprise I found that the isolation capacitor had a broken lead.<\/p>\n

Considering the low price of the radio this was not a surprise.<\/p>\n

To open the antenna just remove the ring nut around the connector and with a small screwdriver widen the rubber that encloses the antenna.\u00a0Slowly unscrew the connector counterclockwise until the antenna comes out completely.\u00a0A piece of heat shrink tubing is placed around the capacitor to avoid short circuits.<\/p>\n

So quickly I replaced the 3 pF capacitor with a new one.<\/p>\n

Before putting the cap back on, I did tests that confirmed that the antenna was working perfectly!<\/p>\n

It is not a big problem to solve but perhaps it could often happen if the antenna were to hit or bend due to a sudden movement.<\/p>\n","protected":false},"excerpt":{"rendered":"
