Re: [Elecraft] XV-144 heat
This is one of the disadvantages of buying when equipment is newly available. There were no holes in my XV144 top and bottom case panels. I must remember to wait awhile in future until all the initial changes have been made. 73 David G4DMP In a recent message, Eric gliderboy1...@yahoo.com wrote ...

Re: [Elecraft] XV-144 heat
Are there holes in the PCB Eric?

[Elecraft] XV-144 heat
This is odd because I drive my XV-144 with 1 mw as well, but at 10W output in digitial mode (1 min tx, 1 min rx) it gets way too hot to survive without a fan. I have one screwed to the shelf it sits on that blows air under the XV-144. Inelegant, but effective. I would like to see a fan retrofit kit as well, perhaps inside the top cover that would draw air through the unit and exhuast it out the top. 73, Eric WD6DBM __ 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
Re: [Elecraft] XV-144 heat
A fan fitted inside the top cover sounds a good idea, Eric, as this would save having to drill a series of holes on the printed board as I have done. However, you would still need to drill some holes in the bottom cover. You can't really draw air out if there is nowhere for it to go in. Having fitted the on-board fan, I have just tried running it at 10W output for 30 minutes on a dummy load. Warm air is coming out of the top vent holes and, taking to top cover off, the PA module is warm to the touch, but not hot. 73 David G4DMP In a recent message, eric norris gliderboy1...@yahoo.com wrote ...
