Re: P3/SVGA Keyboard

Has anyone tried the MFJ-551 RFI suppressed keyboard? This is a PS2 type of keyboard but PS2/USB adapters are cheap. Better yet, any word on when the Elecraft keyboard will be available?

Re: P3/SVGA Keyboard

Maybe I am mistaken but I think I heard of a USB Keyboard option for the SVGA/FFT board coming from Elecraft..... I use all indoor antennas so RFi is pretty much a constant struggle with interconnect cabling like keyboards. Ferrites everywhere. I try to go wireless where I can. Heaven knows what I would be up against if I had a KPA-500. :-))

Re: P3/SVGA Keyboard

Jim,

My understanding is that the USB option for the SVGA board is that it
will *accept* a PC USB keyboard. I have never heard that Elecraft would
be selling a keyboard.

Re: P3/SVGA Keyboard

Well, I guess I was just reading into it a version of my wish list Don. I am currently using a Logitech K120 from Staples. $15.95 and two RS Ferrites. Seems to work OK at 100W. I tested on all bands 80 thru 10 this AM and it checked out clean. But there is a KPA500 in my future I am thinkin'.

Re: P3/SVGA Keyboard

With indoor antennas, I would not want to be in the high RF level
present with 500 watts. You may be OK, but I would "run the numbers"
for the RF exposure limits present at 500 watts given the close
proximity to your antennas.

Re: P3/SVGA Keyboard

If I remember correctly from earlier threads, there will be no "Elecraft
keyboard." Keyboards are basically commodity items. There is no margin on
them for Elecraft to try to get into that market.

Re: P3/SVGA Keyboard

In reply to this post by Don Wilhelm-4

Yep, already done that. All but the full wave 40M loop are fairly isolated, out over the garage area. The 40M loop is about 9' over my head when at the operating position and that was a bit of a concern. Duty cycle of course enters into the equation and that sorta brought things down well into the safe level for even 500w, so I added the safety factor of driving the KPA500 at 10W yielding approximately 300 W at the antenna. That accomplishes a couple of things, one being not have to re-purchase antenna tuners :-)) (I have tuners at the feed points of the various antennas, more efficient that way.)

I've never had an RFI issue with Logitech wireless keyboards and mice.

Hi Jim,

Those inexpensive adapters are passive signal converters, there is no changing of the PS/2 keyboard protocol to USB going on in there. Currently the P3/SVGA board does not support PS/2 keyboards.

The K120 is a bit sensitive. Reduced the power to see where it cleared up and added a couple of ferrites. Good to go.
