Many thanks to all who replied to my query about the vent holes in the top cover of the XV144. There weren't any on mine, so I drilled some over the Metox resistors in the RF power attenuator (R20, R21, R26, R27).
With particular thanks to Johnny VR2XMC, I have now completed my mods to the XV144 by adding a fan, similar to that used in the XV432 and drilling vent holes in the base plate. Although I am only driving the XV144 with 1mW from either the K2 or K3, heating of the resistors was not a problem, but hot air is now coming out of the top vent holes when I am transmitting. Hopefully, the mods will enable the XV144 PA module to run cooler and it will not shut down after I have been transmitting for more than a few minutes. 73 -- David G4DMP Leeds, England, UK ------ ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
