Re: [Elecraft] Strange Interference

Sounds like an SMPS, it may be yours :-) I have a similar noise on 80 only. It sounds like a slight increase in the background noise as I tune across it, but it is much more pronounced on the P3, and it drifts slowly up and down by 20-30 KHz over time. It rises to a 2-3 KHz wide peak, drops

[Elecraft] KX2 Feature request OFS / DISPlay

Using the OFS mode for Course tuning and the Main VFO knob for Fine tuning is great but this is at the expense of the DISPlay function. It would be great to leave the VFO B display set as DISPlay but still have the option to Course tune via the VFO B Knob, rather than changing the tuning rate of

Guys, I've run into something on 80M trying to use the internal antenna tuner. It fails to tune to a low SWR. Brian K3KOI had a similar problem but never quite got to the bottom of it because partly intermittent, possibly multiple faults. In the end to fix it:- a) I rewound one of the swr

Hello David, (and Alan), and thanks to John for the link showing the added parts. David, your PS sounds very similar to the one I built, also in the 70's. Mine has four 3055's on very large heat sinks that are overkill, but I didn't know what to expect. It was at a time when we were going

[Elecraft] Strange Interference

I am operating portable in the southern Puget Sound area currently. I am picking up a strange S9 interference that is very narrow but generally slowly moving down the bands and sometimes up the bands. It occurs at any one point in time at 14.030, 14.060, 14.090 for instance, and occurs on all

Dick, I have only the KX3 - no KX2 - but I can tell you that with the basic unit, no add-on heat sink, operating PSK31 heated up the unit enough for it to fold back just about every time I used it. I put on the heat sink offered by Pro Audio Engineering, did it the optimal way, and it made a

Re: [Elecraft] KX2 Data operation.

What heat issue?  My KX2 runs RTTY at 10 watts.  If the transmit-receive ratio is too high, or if the transmission is too long, the PA temperature may reach the limit where power is reduced to 5 watts. 73, Ed W0YK On Jul 23, 2016 5:10 AM, "Dick,WN3R" wrote: > > I have a KX3

I have a KX3 and never added the third party heat sink, but will probably install the one now offered by Elecraft. I'm seriously looking over the KX2. I'd be interested in hearing from owners of both rigs about digital operation comparisons. How has the heat issue been addressed in the KX2?

Or is of a common thread at both locations. i.e. rather than hauling phone chargers around, I leave them scattered in my usual places (less to move). I do the same with similar devices (not always the stock brand). Switching supplies are common but not all meet or exceed noise requirements.

Thanks to all for the advice. I found the issue. It is my Powerwerx SS30DV Switching supply. I thought this supply was a good one to not create problems like I am having. Not sure if it is fixable or If I need to send it in for repair. Very 73, Terry N7TB -- View this message in context:
