John, I see you are partial to 100 watt machines tuned down. Is the reasoning because of the duty cycle would be cut in half and easier on the machine? I see 25 watt quantars on ebay all day long at about 1k which is quite tempting, but leary of the performance on the lower wattage. Should I hold out for a 100 watt?

Ryan....

sorry man , somehow I missed this.

?what is the difference from 25W to 50W. A 3dB. can easily be made up in the antenna. keep you line losses to a minimum and your antenna gain as large possible.

no need to hold out for a 100W'er.

Kenwood TKR-851 Repeater driving a TPL amplifier with a good Wacom, CELWAVE, or TX/RX duplexer. An old GE Mastr 2 power supply. Feed line at least 7/8" heliax and a Commander PD-455. Perhaps a polyphaser to save all those toys in the rack as well as grounding kits on the heliax/antenna. That's the setup I put in 6 years ago and it sees around 12-15hours of airtime a day. Haven't touched it since it was installed.
