AM receive bandwidth
Hi, all, I'm trying to get the whole signal for WTWW 5085 (listen only.) I have a 13 kHz filter in now, but the K3 limits AM bandwidth to 5 kHz, and WTWW's signal is at least 2 kHz wider than that. Is

Damaged K3S
I agree with Bob, K4TAX regarding repair attempts, especially if the root cause(s) of failure are not fully understood. I had the same question as Dan, W3DKA, regarding active charging of the battery

AM anyone?
I run the same EQ on AM that I use for SSB. I find that the MIC and MIC technique one uses has more impact on the transmitted sound and thus any EQ that might be needed. My setting are as follows: 50

So Mike provided some detailed troubleshooting for you to pursue while waiting for Elecraft. But you asked about what caused the damage. Question - How do you charge/maintain your battery? Dan W3dka

AM anyone?
I realize this is a huge stretch on here but anyone have experience setting up transmit EQ for 6-8kc AM. Do you even want more than 6kc wide. Also getting forward modulation and alc issues. I suppose

Hi Gil, Diode D28 on the RF board is a TVS diode (Zener). The fact that it cracked and burned indicates excess current passed through it due to a voltage exceeding its Zener breakdown voltage. That BZ

Thanks, guys. I was about to ask whether the FM filter would also work for AM transmit, but it appears from other answers here that it does. (The manual says you need an AM filter for AM transmit, but
