I have two 700Ps in the house, and my wife's phone gets substantially better reception than mine. In fact, the RSSI on her phone is typically 10 -15 dB better than my phone. I replaced the radio PCB on my phone with a radio from a donor 700P and saw an improvement of roughly 10 - 15 dB. Since I cannot keep the donor card (belongs to a guy at VZW), is there an adjustment for the radio PCB that will improve reception?
