Title: Cirrus 4ch 40Mhz Aerial Repair
Post by: over_powered84 on July 17, 2009, 04:19:00 pm

Hey Guys
I Have A Problem, Aerial Wire Has Came Loose From The Rx And I can't Find Where It Goes Back To Get It Soldered

I Was Hoping One Of You Guys Might Have The Same Rx And Could Possibly Open It To Find Out Where It Goes With
A Picture Please Guys....It's For My Old Mans HFM Deep Dive

If you scan both sides of the circuit board on a doc scanner then folk familiar with rc electronics could X-mark the location.

Just talking general terms, but normally the aerial is connected via a small capacitor to prevent unexpected DC appearing at the input.  Normally I would expect to see a bit of track with soldered wire on one side and the broken bit sitting down the hole on the other side - since this hasn't been found, it is possible that the aerial was just tacked onto the track side of the said capacitor.  Look for a capacitor near the edge with one end not going anywhere else.

Hi there,

Here you go. I'm sorry about the quality, as the magnication required was beyond my camera.

You will notice that the wire is soldered to a 'black thing' by the blue resistor on the edge of the board. Please do not put your fingers on the tracks of the chip as the static might do some harm.

I hope this helps

Ken

ps .... I posted this once and one of the pics was oversize and my machine froze!!, so here is the second go.  :embarrassed:

pps ....  this took a bit of modifying.  ok2
