Question:Why to replace the parts?I tried replacing the 6220 HF out with the regular HF out like on 7210/6610 and I saw no difference.I left the old antenna switch and the phone works fine.
But the PM looks like a nice job!
Salut!

At all no need to change RX filter, just antena switch, add first GSM amplifier /and some parts arround his circuit/ and change GSM TX filter ...

P.S. There important is "mixing" of 6200 6220 and 72/6610 PM-s to achieve speaker sound, low RF PA consumption and good network reception ...

debeliamark · 12-02-2004, 09:12

And also one more - if someone haven't success with BoOzer's pm - try one attached from me
