[Elecraft] FT8 output power KX2/KX3

What is the recommended max power output setting for the KX2 and for the KX3 for normal FT8 use without after-market heatsink? Thanks & 73, Barry N1EU __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: h

You're welcome. It is such an oasis to find a company that not only makes top quality equipment but has a fantastic after sale support of these products. I Loved my K3, sold it to a friend who wanted one for mobile contesting, with me buying a K3s to replace it. Feeling remorse at selling th

Re: [Elecraft] FT8 output power KX2/KX3

Barry, The normal recommendation is for 50% of the maximum power. The KX3 and the KX2 will roll back power for protection if the PA transistors get too hot. I know the KX3 rolls back to 5 watts, but I am not sure about the level for the KX2. 73, Don W3FPR On 10/26/2017 7:50 AM, Barry N1EU wr

Re: [Elecraft] FT8 output power KX2/KX3

Thanks Tom and Don for the responses. I'll try a few 15sec FT8 xmit cycles at 50% (7.5W) into a dummy load while monitoring PA temp. Any guidance on what the upper safe limit is for PA temp? Thanks & 73, Barry N1EU On Thu, Oct 26, 2017 at 8:34 AM, Don Wilhelm wrote: > Barry, > > The normal re

Re: [Elecraft] FT8 output power KX2/KX3

Barry, You should be able to tolerate 60 degC measured at the PA transistor tabs for short periods. You can read the PA temperature in the Alternate VFO B display. 73, Don W3FPR On 10/26/2017 9:05 AM, Barry N1EU wrote: Thanks Tom and Don for the responses. I'll try a few 15sec FT8 xmit cyc

Hi all It doesn't have to cost $800. A couple of years ago I bought a Chinese quadcopter, complete with video camera, 2GB micro-SD card, card-reader, spare propellers, 2.4GHz remote controller, and including shipping - all for $68. But I think the price has come down now. The total "diameter" of

[Elecraft] P3 SVGA macro editor

Is there anything in the works to provide a macro editor for the P3 that allows creation and editing of the 50 macros in the SVGA? That would be really helpful and a vast improvement over the present, very limited, editing capability. Chuck TeagueNN7U 

Re: [Elecraft] FT8 output power KX2/KX3

The KX3 specifications in the manual (page 54) say 5 W for digital modes. I expect the KX2 specs also list a power level. "Supply voltage of 11 V or higher (on key-down) required for settings above 5 W. 5 W or less recommended for high-duty-cycle modes (FM, AM, DATA). Power will automatically be

[Elecraft] KXPA100 not transmitting

Is anyone running a Elecraft KXPA100 amp with KXAT100 with a KX2 or KX3 that could help me with a little troubleshooting? The power amp light blinks slowly (not on steady) and while turner tunes, the amp will not go to transmit but shows 25 W output. I am using the KX2-controled connection. M

Re: [Elecraft] KXPA100 not transmitting

The KXPA100 blinks a LED while ATU TUNE is in progress. The ATU TUNE needs steady carrier from your KX2. ATU TUNE is done with exciter power, and when it's complete, the amp can be switched in. 73 de Dick, K6KR -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-

Re: [Elecraft] KXPA100 not transmitting

Sam, That is normal operation while the KXAT100 is tuning. See the KXPA100 manual page 25 "ATU Tuning". The power is limited to 25 watts while the ATU is tuning and the 25/SWR LED under POWER OUT blinks. Note that ATU is different than TUNE - see page 19 in the KX2 manual. 73, Don W3FPR

Re: [Elecraft] In praise of the sub Rx & Diversity - Addendum

I don't know all the technical details of diversity reception but have wondered if a diversity mode option board could be produced at a cheaper price than a full-blown sub receiver. Not sure how much I'd be willing to pay but sub-receiver pricing is definitely a no-go. 73, Drew AF2Z On 10/2

Re: [Elecraft] In praise of the sub Rx & Diversity - Addendum

Probably not. Diversity reception works because there are two matched receivers, even matched in phase of the detected audio. That allows the best signal to win based just on the signal, not the receiver. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Oct 26

I use diversity on 20 meters with a vertical SteppIr and a loop. Both are separated about 150'. What a difference. Amazing. Makes a huge difference with stations fading in and out and near the noise level. I can work them with the Loop, but the vertical is so helpful when receiving. 73, Bil

Re: [Elecraft] In praise of the sub Rx & Diversity - Addendum

Drew, True diversity reception requires 2 receivers which are locked together in not only frequency, but also in phase. The KRX3 receiver is of the same design and implementation as the main receiver, making diversity reception possible. The antennas must be different, one horizontal and the

[Elecraft] K2 Bad CW signal

Dear community I am having problems with my K2. I got complaints about a lousy signal (e.g. rst 591). When I checked my signal with an external RX I heard a kind of a noise instead of a clean CW signal. When I press the "Tune" button, I have a very clear tone (as usual) in the control-RX. With
