Hello,
I am not a huge fan of the chinese radios, but this one was given to me. It transmits and receives quite well overall, but the problem I have with it is a bit odd. The channel selector does not affect transmit freq at all. And, I noticed when adjusting the VCO it acts like a VFO. The radio never loses lock and I was seeing it vary from 10m freqs all the way down around 10mhz. The radio never loses lock it seems. Of course the power out and receive drops off as expected into the dummy load. I was just wondering if anyone had ever run into this? The only thing I did notice is this radio is fitted with a socket for the PLL chip and has a Fujitsu MB8719 installed.
