Re: Removing surface mounted resistor #ubitx

Hi Robbie,
I was hesitant as well, in the beginning.? I am blind in 1 eye.? I have no depth perception.? I can do it.
I watched several youtube videos on removing parts.? Here is a good example:?

After watching a few videos, I was confident.? Make sure you use plenty of flux and a fine tip.

Good luck,

I have the R3 board, and have tried to duplicate the anti-pop cct from the R4 schematic (current on a proto board).
The mod works ok, in that there is no 'pop' on transitions between TX and RX, but the CW sidetone is no longer coming through the speaker...

I want to try changing the value of R70 from 10, to 1000 Ohms (as per Rev4), but I've never tried removing a surface mounted component before, and a bit scared of damaging the board/resistor (in case I need to put it back).

Can anyone advise how best to go about this please?

I'm even toying with the idea of cutting the tack on either side so I can bridge the gap with a new value (or feed lines to my proto board for testing of various resistances...
