Fw: [Elecraft] 10m Birdie

I never operate 10M but just checked my K2 with the KPA100 and found the same thing with a strong birdie at around 28262. The weird thing is that when I turned off the KPA100 (reducing power below 10W) the birdie at 28262 shifted up about 1kc and the birdie at 28019 shifted down about 500c.

[Elecraft] Fw: Interesting K3 QRM problem

In this recent discussion here on K3 QRM from strong local broadcast stations, W4TV brought up the noise generated in the T/R switching diodes. In doing some experimentation with a bandpass flter in the loop between the RX antenna out and in on the KXV3A I have discovered something which has

Re: [Elecraft] 12 meter K3 RFI from nearby FM station

What power are you running?  Try an experiment by turning the power level down or up thereby switching between the LPA and the KPA3 to see if this changes the intermod level. This may narrow it down to the TR switch.   I have had a similar problem with intermods between a couple of local AM

Re: [Elecraft] K3S Microphones

I have K3 S/N 732 and use a $2 electret computer mic I bought at a yard sale.   They had a white one that was only a $1 but I chose to go the more expensive route and buy the $2 black one to match the K3.  My settings are -16db  up to 400 Hz, 0dB at 800-1600 Hz, and +16 dB at 2400 up and I get

Re: [Elecraft] Current Draw on 20M

After reading your numbers here I was curious since my K3 is the same vintage as yours, serial 732, Apr'08.  I did a quick check on 20M and I am reading 15.5A, @13.5V (on my Astron 20M meters) at 100W into a 50 ohm dummy load.  I checked other bands and read the following: 160M-15.5A, 75M-14A,

Re: [Elecraft] KBPF3A switching frequencies and performance

Just an FYI, I found out what the problem is with my modified KBPF3.  I removed the added caps and signal levels returned to somewhat normal levels.  Adding a cap to C2 didn't make sense and attenuated the signals. But Fig. 14 shows adding a cap to C4.   Apparently the ham I bought this from

Re: [Elecraft] KBPF3A switching frequencies and performance

Brian,Thanks for your information which got me thinking again about my situation.  I went back and set the config for the KBPF3 to "not inSt"  and found no difference at the signal levels at the switchover at 1700 Kc.  Toggling back and forth between "not inSt" and "nor" I verified that there

Re: [Elecraft] KBPF3A switching frequencies and performance

Thanks Ben, I didn't think of that.  Now when the KBPF3 is not inst There is no difference in signal level when transitioning from 1.700 to 1.69.  And when I set the KBPF3 to nor (and reboot) there is a definite drop of 5-7 S units at the 1.700 transition point and also at the the 2.11 to

Re: [Elecraft] KBPF3A switching frequencies and performance

Hi Ben: You had me curious with your request.  I started to check my KBPF3 (modified to the "A") and noticed something that now bothers me.  I tried going down from 160M and it appears that the switch over to the AM broadcast band occurs precisely at 1700,000  Kc.  When I tune to  1.69 the

Re: [Elecraft] KBPF3A switching frequencies and performance

Hi Knut: I couldn't tell you if this is a new problem as I didn't notice anything amiss until I started checking switchover frequencies to answer W4SC's question.  I verified that the KBPF3 is enabled in the config menu.   I bought the used KBPF3 about 4-5 years ago from another ham and don't
