Haven't tried it without a fan. I would guess that the giant heat sink on the original PA would probably handle the heat easily. My only concern would be the small contact area from each module; Would the heat dissipate properly? I have a PhD physicist business partner who could figure it out, but it's about as easy to add the fan.
As K7IOU pointed out in the PA site, the fine print on that particular RF module says that the unit was not appropriate for repeater use due to the duty cycle. Not sure why they came to that conclusion. Of course, he read that AFTER the modules had been purchased. So, we went with them anyway. Almost two years later... go figure. de WD7F John in Tucson ----- Original Message ----- From: "Nate Duehr" <[EMAIL PROTECTED]> To: <Repeater-Builder@yahoogroups.com> Sent: Saturday, July 14, 2007 6:41 PM Subject: Re: [Repeater-Builder] Re: 224 MHz PA fun and war stories If a PA can't handle 48 hours of continuous key-down as-installed (fans if one must, etc.), it shouldn't be used on a repeater. > You can find it on K7IOU's micor conversion page at > http://home.comcast.net/~micorrepeater/220mhzpa.htm Thanks for sharing, John.
