It is a rare AMP that is no longer in production. The V/U dual machine is very convenient. "Product condition" The appearance of the main unit is only a small scratch, and there is no major damage. Well, I think she's pretty. The accessories are the main unit and (instruction manual, DC power cable, REMOTE terminal plug). The manual has a circuit diagram. The red and black wires of the power supply have additional extension cords. The remote plug is for 2m and 430 calicon, connect with this machine at SSB. Although there are images of the internal circuit board, there is no burning or discoloration of the final stage circuit and it is beautiful. "Operating status" We did a simple operation check before listing.
There are transmission power measurement images of 144M band and 430M band. The 144M band had an output of over 100W.
The 430M band had an output of about 90W. There is a 10W/25W switch on the bottom for input switching. This time, I used the TS-790 on the 10W side. In SSB mode, the output remained unchanged.
If the input is over, the Warning lamp will turn on and the operation will stop. It recovers by turning ON/OFF the power switch. The power will fluctuate due to changes in input and power supply voltage, so please adjust with the radio you are using. Reception seems to work on both bands. I also checked the change in the reception level adjustment. However, we have not tested the actual communication.
We do not mark merchandise values below value or mark items as "gifts" - US and International government regulations prohibit such behavior. The power will fluctuate due to changes in input and power supply voltage, so please adjust with t.
