Thanks for the information Kevin,
I have some factory made 5 watt, 3dB attenuators. If your custom made 10 watt
amp was turned down to five watts and the attenuator was used I could get my
2.5watts for the one PA and my 5-10 watts without the attenuator for the other.
Do you see any problem using the attenuator with your PA so I could drive the
lower power input PA if I needed?
What does Repeater Builder (the business) get for the Custom 10 watt amp?
Thanks JIM KA2AJH
