[Elecraft] K3S misbehaving

Hello list My K3S seems to be misbehaving in that the CW receive audio level starts distorting/crackling when audio level is above about 25 percent. The SSB audio levels seems a bit low but no distortion with max volume. Does anyone out there have any ideas on what could be causing this type

Re: [Elecraft] K3s Notch Filter

Yes, I really wish the K3s could do that. I also wish it had multiple notch filters. As it is, it’s so wide that you can’t help silencing a good size chunk of the band. Hardly practical. Maybe corporate feels that FT8 is just an evanescent craze that will soon go away, thus no need for

Re: [Elecraft] K3s Notch Filter

It appears from my measurements that the manual notch is about 200 Hz wide at the 6 dB points.  That's the width of only 2 FT-8 signals and the depth of the notch is about 40 dB.  Certainly will take out 1 or 2 signals and not affect others in the 2.7 kHz BW of the normal FT-8 receiver

Re: [Elecraft] K3s Notch Filter

1). The design of the K3 notch filter predates most digital modes currently used (excluding RTTY). Earlier digital modes, were wider. It may be possible to change the behavior. 2). The use of legal limit or not isn’t the issue; as it may be needed to make the DESIRED contact, typically

Re: [Elecraft] K3s Notch Filter

Unfortunately you can’t. I miss that feature from several other lesser radios. You could target a particular audio frequency and set the width of the notch filter and make the offending sound go away! Hank K4HYJ From: Richard Sent: Sunday, May 12, 2019 6:24 PM To: Elecraft Reflector Subject:

Dear all, I have a XV432 that seems deaf compared to my ICOM IC-7000. When I tune to a local beacon on 432.300 MHz, I can copy it clearly on the IC but nothing is heard on the XV432/K3 with KXV3B. I checked transverter set up by feeding it a signal from a signal gen. It has a

Re: [Elecraft] XV432 deaf

Raj, Has this XV432 worked before and recently developed weak receive? If so, try peaking the RX input capacitor, and if that does not correct it, replace the PHEMT (ATF34143). If you recently acquired it, check the configuration jumpers for the 28 MHz IF - do you have a single coax and it

Re: [Elecraft] XV432 deaf

Thanks Don for your prompt reply. I built it a few years ago and I think it worked then. I just got back into UHF and thought to check it out. So, I am not sure if it worked before. I have peaked the RX cap and LNA bias. I measured the gain across the ATF to be 10.5dB. Does that indicate

Re: [Elecraft] XV432 deaf

Raj, I have not measured the gain of the ATF stage by itself.  That is difficult to do because the measurement probe can induce and pick up stray coupling at VHF/UHF frequencies. I normally judged the overall performance of the XVseries transverters by injecting a -140 dBm signal
