Re: [Elecraft] K3S's built-in RTTY

This RTTY system configuration is the worst one I can think of (sorry!). The RTTY receive will be great for you and transmit will be greatly compromised, for both you and your QSO partners. Once you have a PC/modem interfaced to the K3S for receive it is trivial to use it for transmit as well.

I can tell you that being on the other side of that kind of QSO can be painful, even with something as simple as a contest exchange. From that point of view, the paddle is acceptable only if you can send about as fast as RTTY. Not a lot of hams can. :) 73, Jim K9YC On Wed,3/8/2017 7:42 PM,

Hi, Can you give me a list (frequencies) of your worst birdies and I will check if I have them. In general I have not found many bothersome birdies in the K3S, but there are some. If I don't have them, there is clearly something wrong with your radio which may warrant a return to Elecraft. BTW, I

The KX2 was pretty thoroughly reviewed by Peter Hart in the January 2017 edition of RadCom. Without trying to reproduce the receiver data tables, some representative numbers are: 3.5 MHz close in IMD (500 Hz bandwidth, 2 kHz spacing with preamp off) yielded a 3rd order intercept of +15 dBm

I think the Sherwood ranking to KX2 means nothing unless you have a KW amp (e.g., Expert 1.3k after mods) and run it in a contest or DXpeditions. After all, nobody will hear you. Also nobody will hear your IMD3 except your next door neighbor. The biggest values of a QRP radio are: 1) convenience
