Hi Stan,

I would use the latest "one-click" production firmware release (MCU 2.69/DSP 1.49). This corrects a DSP problem that in rare cases could result in the DSP not sampling signals correctly.

Subject: [Elecraft] (KX2) - Randomly Powers Up "Weird"

For the last couple of months my KX2 randomly comes up acting like it has a very tight filter engaged although all screen indications are normal. In plain language it sounds "hollow" as if it were at 50 Hz. Yet all screen indications are normal (for example, it shows 400 Hz from its last use). There are no error messages.

This is very random; not a regular event. When it does occur, all I have to do is turn the power off and then immediately back on and all is well.

My KX2 is connected to an SEC1235M power supply and is also connected to the KXPA100 amplifier. It's always in CW mode because that's all I use. This "weird" power up situation occurs even if the KXPA100 is physically disconnected.


The KX2 otherwise works normally in all regards. My firmware is at 2.61, DSP at 1.46 and PA at 1.32. These are "as shipped" by Elecraft at purchase time. My serial number is 0472.


Just wondering if this little issue has visited anyone else.


73, Stan WB2LQF
