Re: [Elecraft] K3 TX-INH
Hi Stewart, what's the reason behind? If you want to make sure the remote K3 does not stay in TX state when you loose the connection it depends on your solution. If you're using the Remoterig boxes they take care of it automatically. As soon as the connection between both controllers fails the remote RRC shuts down the remote K3 completely. Concerning TX-INH: Yes, you can do it that way. This is what I use in my K3 sequencer, too. Detect PTT from KEY-OUT as the trigger. Keep TX-INH pin high or low (depending on menu setting) to avoid any RF until you release it. The K3 will be in transmit mode but not emit any power when TX-INH locked. 73, Olli - DH8BQA http://www.dh8bqa.de > Stewart Bryant hat am 5.

Re: [Elecraft] Duty Cycle on the K144XV transverter?
Hi Jim, I have used my K3+K144XV extensively on a 2 m Meteor Scatter expedition last year. Besides high ambient temperature during the expedition also the K144XV develops heat quite quickly. It does not take longer than 5-6 WSJT transmit cycles for it to get warm enough it starts reducing output power. The longer it runs, the worse the power reduction (my one started at 9 watts out and settled at about 5.5 watts after half an hour running FSK441). What helps a bit is a fan oriented on the left side of the radio as the K144XV uses the side panel for "cooling". Even better is not to run the transverter at full power out. So as you are just starting searching for an amp I'd suggest to look for one that just needs 5 watts input and drive the K144XV at that level. Takes away a lot of stress from the finals, too, I'd suppose. But still a fan might be useful if you'll do it for a few hours (like I did). 73, Olli - DH8BQA > Jim Rogers hat am 24.
