There is a 25 watt uhf model but it has only 4 channels and is capable of 40 watts also by adjusting a pot inside but it does not have enough heat sink to run at 40 watts more than a few seconds so I would not advise it even with a fan. wb5oxq ----- Original Message ----- From: Kerincom To: [email protected] Sent: Wednesday, October 01, 2008 9:38 AM Subject: [Repeater-Builder] Maxon sm4450
