Re: [Elecraft] Linear PS Recommendations

Since the KPA500 has its own linear supply, you probably don't need much more than 20 amp capability. I have used an Astron RS-20 for the past 35 years but I would probably go for the RS-35 or RS-50 if I was getting another one. 73, Bob N7XY On 7/20/16 5:57 PM, Clay Autery wrote: I am

Mike, You technically don't have to move the filters in the KRX3, but it just makes more sense to me to have them match. Yes, if you do not have the K144XV in your K3, then there is no real sense in installing the 13kHz filter (unless you want to do AM transmit with that filter). 73, Don

Re: [Elecraft] How difficult is it to install the FM filter ofr K3 with ...

Mike, Not a big problem, but you do have some mechanical work to do. Remove the 2 meter option and the KRX3. That will expose the filters for the main receiver. The 13kHz filter should go into the FL1 slot - that means you may have to move and reconfigure all the other filters installed in

Knut and all, I do agree with that *and* if the band is 40 meters *and* if the KPA100 is not the latest design T/R switch it is entirely possible that there could be a spurious response above the 40 meter band during the time it takes to do the antenna tuning - this may cause the ATU to tune

William, That indicates that either you have a bad coax between the K2 and the tuner, or the tuner's SWR meter has a problem. If you have an antenna analyzer, connect it to the same coax that you connect to the K2 and see what it indicates. It may be that the KPA100 wattmeter could stand
