The aux DSP adds around 100 mA even when the sub receiver is turned off, as I recall, so some increase in temperature is normal. The KRX3 module itself adds nearly zero current when turned off, and I don't believe it could cause any increase in temperature since just due to its location above the RF board. When turned on, the KRX3 adds about 150-200 mA. All of the components are rated to handle much higher temperatures than you normally encounter (typically 70 C). However, I've never seen an FP temperature of higher than 41C, so if you're seeing 44C, you might check your FP temp calibration. Even 44C is very unlikely to be a problem. 73, Wayne N6KR --- http://www.elecraft.com _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
