No, that's not true!
I had one of the first batch in 2006 and it was a nightwatch. 'Looked real pretty in the dark.
It was also a POS and I had to send it back and traded it on a Magnum S9; never looked back.
It looked great on paper, but the transmit went south on it.  |

To answer your question here are the first to last production runs I know of.
PCB numbers
PFM-0090A-BA, PFM-0090A-BB, PFM-0090A-BD, PFM-0090A-BE, PFM-0090A-BF
I agree with Bert, I personally had 5 of these paper weights with frequent flyer miles to the repair center, and the last was a new unit returned, and there last up to date version. All 3 had to be returned to there service center for repairs with in 30 days of receiving it.
The 1 mosfet driver RD16HHF1 that pushed the 2sc-2290s would go bad, inherent problem with these units in combination with the gate voltage to the driver being set pass 3 volts and over heats the transistor. Another problem is this unit is very sensitive to static electricity, like high winds blowing as a storm approaches, static electricity on your antenna, tower. Always need to worry about disconnecting your coax and unplug the power supply even if everything is grounded. Basically the radio has poor to no static bleed off to prevent this from happing. One day you could be talking on your radio and then turn it off, next day turn it on and have no transmit. Don’t waste your hard earned money. |
