Re: [Elecraft] [K3] Broadcast interference on 160M

Hi Bill, I haven't heard anything like this myself. If you find a repeatable way to make it occur, please pass it along and I'll try to duplicate it. Meanwhile, the workaround sounds like switching bands, then back to 160 m. 73, Wayne N6KR On Dec 1, 2015, at 2:51 PM, Bill Frantz wrote: > I

Re: [Elecraft] K3S Time Clock

Hi Bob, The RTC's clock is supposed to be calibrated at the factory to something far better than this. Please contact customer support. The K3S front panel board has a trimmer on the RTC crystal, so if you have a counter you could attempt to dial it in yourself. The frequency is supposed to be

[Elecraft] Bands are more open than usual today

At least here in N. CA, I'm hearing a lot more 10-meter beacons than usual, and lots of activity on the higher bands. Maybe we should all pile on? I've been making a lot of Q's on 20 m with the the KX3's built-in RTTY and PSK31 modes at 10 W, thanks to the new PX3 keyboard firmware. Given the be

Re: [Elecraft] K3 DSP processor speed

The K3's DSP code is written in very efficient assembly language. It executes quickly, because it doesn't need the lengthy library-routine calls typical of the C or C++ code written for GHz-clock DSPs. The code is also extremely compact. The crystal oscillator frequency is not a direct indicat

Re: [Elecraft] K3 QSK CW Audio Dropouts

We're talking about two different things. What OK1RP may be hearing is the ATU switching its relays when he first transmits in a band segment that requires new LC settings. The firmware attempts to do that between CW elements (in RX mode). This should be extremely rare. (If it's happening more

Re: [Elecraft] IMD and supply voltage

Greg, Even a rig with predistortion capability will run out of steam and exhibit greater IMD when running from low supply voltages. Predistortion attempts to compensate for the compression by increasing drive, but there must be enough headroom to allow the algorithm to work. Note that the rear

Yes, we made sure compression was off. We gave the unit every opportunity to exhibit magic properties. Alas, it did not. Wayne N6KR On Oct 29, 2015, at 2:10 PM, Chip Stratton wrote: > Interesting results about the Icom M-802. It is actually marketed as a "150 > Watt" rig, so testing it at 1

Jim, This appears to *not* be true, at least for one radio lauded by those concerned about TX IMD. Earlier this year there was a long forum thread on Eham.net lamenting the "fact" that 12-V ham rigs were not as clean as 12-V marine rigs. One radio in particular, the Icom M802, was touted by fo

Re: [Elecraft] IMD and supply voltage

Frank, All radios that run from an external DC supply (to make them usable with emergency power sources, such as a 12-V car battery or solar panel) are subject to increasing TX IMD as supply voltage goes down. But such radios are virtually all specified (by the manufacturer) and tested (in QST

The speaker amplifier and driver stages that were redesigned are on the DSP board, not the KIO3B. The KIO3B does have new audio circuitry, namely a CODEC and support circuitry for merging line-level audio with control data for use by the new USB port. But this has nothing to do with the speake

We've made several changes to improve audio over years, and a K3S incorporates all of them: - K3: improved 12VDC decoupling to the AF amp - K3: added a dual low-noise LPF to eliminate residual sampling noise (mostly at 12 kHz) - K3: corrected DSP AGC algorithms, which were non-monotonic at so
