1. [TenTec] Orion - cooling fan (score: 1): Author: tlogan7@cox.net (tlogan7@cox.net); Date: Sun, 5 Jan 2003 23:33:16 -0700; Hi folks - The TT info on the Orion describes a 100% ICAS Tx duty cycle with user supplied cooling fan. What does ICAS mean and does the Orion have an internal fan? Thank you. 73/Tim; /archives//html/TenTec/2003-01/msg00085.html (7,338 bytes)

Several definitions around for ICAS numerically but it is on the order of 5 minutes on and 20 minutes off, for example. The important point is that it i; /archives//html/TenTec/2003-01/msg00087.html (8,654 bytes)

The well-known rule of thumb is that decreasing the temp by 10 deg C produce; /archives//html/TenTec/2003-01/msg00131.html (12,026 bytes)

Personally, any solid state radio I have, if it does not have a fan on the heat sink, I put one on it. Doesn't have to be elaborate, just something to move the air sur; /archives//html/TenTec/2003-01/msg00146.html (8,709 bytes)

Therefore there's no hmmmmmmm. The transmitter is rated at 100% duty cycle with a 20 minute limit.

If there's a 20 minute limit, it seems the duty cycle would then be split with the amount of off time. Would also seem to allow 100% duty; /archives//html/TenTec/2003-01/msg00157.html (7,648 bytes)
