[Elecraft] Help with defective KFL3A-400 needed

Hello everybody, I have a friend's KFL3A-400 on my bench which shows a 20 dB passband attenuation with high ripple. The fault was originally detected by a 3 S units signal drop in the K3 compared to its other crystal filters. The filter was working perfectly until recently. I disassembled

Re: [Elecraft] KRC2 and KX3

Hi folks, I'm trying to interconnect my KX3 and KRC2. I read the posts on this topic dating back to early March. The KRC2 is a very versatile unit allowing parallel operation of band filters via the BCD outputs and antenna relays the same time. So I would really like to get the KRC2 running

[Elecraft] Issue with mounting KX3 RF board Rev D

Hi everybody, I'm just putting together my KX3 kit. While mounting the RF board Rev D to the bottom cover I zipped off one of the M-F standoffs using rather little force. As I usually have a good feeling which force may be used on these standoffs I started investigating things a bit. After

[Elecraft] Need help wid KRC2 config utility

[Elecraft] KPA100 oscillating

Hi Elecrafters, just returned from my 2005 WAE CW activity in LX, where I operated my K2 on a camp site in a fieldday-style operation. So far all went fine. Even a high power (100 kW +) MW transmitter with really big antennas only 1 mile away didn't produce any problems to the K2 RX. And I

[Elecraft] Which audio level variation over full AGC range acceptable ?

[Elecraft] Strange IF Overload problem with XV50

Hi Elecrafters, just finished my XV50 and hooked everything up with my K2. So far all is fine, but I have a strange problem with the XV50: I have set the t-r time to 0.05 s (semi break-in) and every now and then the XV50 goes into IF overload condition (all LEDs flashing). As I couldn't
