Hi everyone, For those who have experience with the Eimac 7289 or equivalent power triode, what is the maximum reasonable anode cooler temperature that I should not exceed in order to get a good tube life? I see 85 degrees Celcius using an IR thermometer after several minutes of calling CQ with 150W output on 1296MHz (dual-7289 amp). Note that the cathodes also have forced air cooling though vents on the cavity walls. Thanks in advance. Bert, VE2ZAZ

As in the past years this is meant to be a truly random event. In order not to diminish the fun for others, please do not reveal the actual call sign in clusters, chats etc. in case you've already worked us. However, if your station is small and you feel more comfortable with arranging a sked with us, then feel free to drop us a line by email to make a proposal in accordance with the preliminary band schedule published on this reflector earlier. The email in box will be last checked on Tuesday night, 24th of May. Thereafter, email communication might be disrupted or sporadic at best, as we expect to have no (continuous??) internet access on the site. This year, the DXpedition site is again more prone to weather imponderabilities, so expect unforeseen incidents – we do at least ;-)) 73/88 de M & M - team WB7QBS: doing sun noise checks on 70 cm.
