I'm not sure where the article went, but it was very simply retuning the vco voltages. If you grab a service manual and look at the alignment section. it will give three frequencies to check the vco voltage. Change the vco tuning frequencies and tune for specified voltages and all should be good. Much of the overseas market goes down to 440Mhz for commercial so the radio is designed to go there, but for US it is tuned upward. Now I'm trying to interface one with my TKR-840 to act as it's transmitter instead of the internal 5 watt one.
