Next to the Yaesu FT-920 of FT-1000MP this Quadra VL-1000 looks very good!
Its additional features in combination with these Yeasu rigs are very nice too.
QSK works fine.
The diplay is nice and easy to read out.
Output signal is very clean.
However there are two improvements on this amplifier:
- the noise of the ventilators, which is very annoying
- the VP-1000 starts 'screaming' when the output is more than 600 Watts
The noise of the ventilators - when the amplifier is 'standby' - is comparable to a desktop computer.
As soon as you start transmitting (PTT) the ventilators of the VL-1000 immediately rotate much higher and the noise of the ventilators gets annoying.
When you transmit with high output and during a longer period (e.g. one minute of more) the ventilators of the VP-1000 come up and the total noise of the Quadra is like the noise of a vacuum cleaner...
The 'screaming' of the VP-1000 when you use high output (>600 Watt) could be fixed, but is not simple to do. I heard more Quadra owners about this.
I sold the Quadra and bought the Acom2000A. This amplifier is EXTREMELY SILENT! It sounds like the amplifier is switched off. You have to listen very very carefully to hear some very little noise. This is the way to go...
When you like the look of the Yaesu combination or when you don't like High Voltage amplifiers the Quadra is a good choice. But be aware of the ventilators noise!
