Re: [Elecraft] KX2 added to Sherwood's list
We found the problem; turns out to be in the setup command to the DSP, not in the DSP itself. With any luck we'll have it fixed this week in both rigs.

Re: [Elecraft] KX2 added to Sherwood's list
The problem described below also exists in KX3, That is why I always adjust bandwidth to 50,150,250, 350 etc Hz. 73, Igor UA9CDC 01.08.2017 16:25, John Reilly пишет: Here are the odd details on the KX2 filter leakage. If the filter bandwidth is 500, 400, 300, 200 or 100 Hz, filter leakage makes the measurement at 2 kHz impossible. On the other hand, if the filter bandwidth is 550, 450, 350, 250, 150 or 50 Hz, then the measurement can be made. The League chose to publish a 2-kHz dynamic range in QST even though the measurement cannot be made on the high side with the standardized 500-Hz filter bandwidth (or any even bandwidth value). Note: Both the League and I only publish the LOWER of the two measurements. Let’s say the low side dynamic range of some radio is 95 dB and the high side is 90 dB. Both the League and I publish the lower worse-case 90 dB number. In the case of the KX2, I couldn’t pick the lower of the two readings since no measurement is possible when using the standard 500-Hz filter. Since the 2-kHz dynamic range value could not be made with the standard filter bandwidth at 2 kHz, but could be made at a 3-kHz signal spacing, I published that data. It may be of interest that the 2-kHz dynamic range number with the non-standard 450-Hz bandwidth was only 1 dB worse than the 3-kHz value. The point of listing the 3-kHz value, or any other radio with a non-2 kHz listing is to point out the radio has a limitation in its filter performance. My long form report on the KX2, available in PDF format, goes into detail about this issue, and has data on the two radios I tested, listed by serial number. At this point, Elecraft does not know why the KX2 behaves this way, or whether there is a possible firmware fix.

Re: [Elecraft] KX2 added to Sherwood's list
A ”temporary” FW fix may be to make the BW settings reside on 50Hz boundary’s every 100Hz i.e. 150,250,,,2150,,, as adjusted.

Re: [Elecraft] KX2 added to Sherwood's list
The cause of this is likely to be straightforward. One of our software engineers is looking into it. Once we have the fix in place, we hope to get a KX2 to Rob for retesting. A temporary workaround (if needed due to QRM) is to use 450 instead of 500 Hz, etc. Wayne N6KR http://www.elecraft.com > On Aug 1, 2017, at 4:25 AM, John Reilly wrote: > > John, N0TA, forwarded this question to me about why I listed the KX2 close-in > dynamic range at 3 kHz rather than the more typical 2 kHz.

Re: [Elecraft] KX2 added to Sherwood's list
Just a couple weeks ago I took my KX2 out to a local park during my lunch break and made a contact using it as a HT, using the MFJ-1820T and a 12' counterpoise. From setting it up and makinge a quick 20m SSB contact took me all of about 3 minutes.

Not 'hand held', but I did use the MFJ telescoping whip for 20m with a right angle BNC adapter with the KX2 next to me on a park bench a couple weeks ago and worked AZ from MN. With the internal battery, that whip, and some wire for a counterpoise, it takes almost no time to set up.
