Low Power Problems with standard power GTX-900 mobiles
Posted: Thu Feb 16, 2006 5:39 pm
Hello again,
My next dilemma is a low power out problem with several low / standard power GTX-900 mobiles, both Privacy Plus (M11WGD4CB1_N) & LTR (M11WGD4CU1_N) versions. On many of the radios, it seems like the transmitter is dropping off at around 927.425 MHz to 927.500MHz. This is a problem since our local repeater is on 927.500 MHz, and we would like to have talk-around (on the repeater output) programmed into our radios. Without sacrificing too much TX power on the lower end (i.e. 902.500 MHz), is it possible to adjust the transmitter’s VCO to lock at higher frequencies?
We attempted cloning the code plug from a radio that works just fine at the higher frequencies, into one of the radios, which does not work at the higher frequencies. Unfortunately, this didn’t change the parameters of the target radio’s transmitter.
Has anyone run into this problem, or for that matter found a viable solution?
Thanks,
trg,
