K-2 and digital question

Has anyone connected a RigBlaster with their K2 for SSTV or PSK-31? If
so, I'd like to contact you off-line as I have some questions. I've wired the "pins" in the RigBlaster per the instructions for Elecraft and hooked it up to the computer properly but no luck receiving, etc. Thanks in advance for any help! 73, Cary, K4TM K2-100 #5266 Lynchburg, VA [hidden email] _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Please send the responses to the reflector? I am sure many of us are interested!

I'm using a RigBlaster Plus with a K2 and MixW, and it's been trial-and-error to get it set up for data (PSK-31, etc). I would also be interested in what others had to say about the setup.

Only two responses so far... Well, after a lot of experimenting this weekend w/ the K2 at minimum power into a dummy load, I finally got it set up for BPSK-31 and actually made a QSO on 40 meters with a station in North Dakota, halfway across the country, w/50 watts into a lossy dipole. I have recordings of what the various modes are supposed to sound like, but I haven't found a source of what they are supposed to look like on the MixW waterfall display. I have learned to recognize the BPSK-31 signals, though. There are several that I see that I can't identify, and of course I recognize the big Navy encrypted syncronous RTTY signal on 5346 kHz (60 meter band) which cannot be detected, let alone decrypted, by the usual stuff that we hams have, (I've heard that stuff for most of my ham and professional life) but it's a good 60-meter "beacon". The setup I stumbled across has a few things that are not intuitive and I don't know if this is the optimum setup or if I missed something, but that's what the reflector is all about. I've taken the liberty of posting this to the reflector in case anyone there can help us get it set up "right". Enjoy the rest of the weekend, have a safe trip home, and we'll be in touch. -- 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

To the original poster who could not even receive.
The RigBlaster is not used during receive. The audio goes straight from the K2 (I use the ext speaker jack) to the Line IN jack on your sound card. Until you can properly receive PSK, SSTV, RTTY, etc, there is no point in connecting up the RigBlaster. Once you have receive working, the instructions supplied for the K2 should work for transmitting but that will depend upon how you wired the microphone connector on your K2. Make sure you have the RigBlaster jumpered so that the signals appear on the same pins as they do on your microphone. The only problem I encountered was not being able to use the microphone through the RigBlaster due to hum on my audio. I suspect this is a grounding issue caused in part by not having the microphione jack in the K2 grounded in my version, S/N 2221. Next time I open it up for mods, it is my To Do list. 73, Mike WA3KYY At 07:55 PM 9/1/2006, Phil Kane wrote: >On Wed, 30 Aug 2006 11:02:12 -0400, H.Cary III wrote: > > >Has anyone connected a RigBlaster with their K2 for SSTV or PSK-31?

I have the RigBlaster connected to one computer serial port and the K2 connected to another for remote control via Ham Radio Deluxe. The main question I have is if there is a better way to get the computer to trigger the transmiter than to use the VOX. >The only problem I encountered was not being able to use the >microphone through the RigBlaster due to hum on my audio.

Phil and all,
The Rigblaster is capable of controlling PTT from its serial port connection. I don't have a RigBlaster, but I just looked at the schematic and see that you must have P5 pin 1 jumpered to pin 10 (PSK31 programs control PTT with the RTS signal), and you must jumper P1:B pin 18 to whichever pin you use on your K2 mic jack for PTT (if your K2 is wired for the Elecraft configuration with mic pin 2 as PTT, you would wire P1:B pin 18 to P1:B pin 25). That should allow the RS-232 interface, the Foot switch as well as the front panel mic input to control the PTT line. Of course, the AUTO/VOX switch should be in the AUTO position. I don't know how that squares with the Rigblaster instructions, but it is what their website schematic indicates must be done. After looking at the Rigblaster schematic, I am amazed that they did not include a transformer in the headphone jack to soundcard connection. What that means is that despite all the optoisolators used in this unit, the headphone jack connection negates any other attempts to isolate the computer ground from the transceiver ground. Now I realize there is yet another reason for all the hum and noise complaints about the audio when the Rigblaster is used. I would strongly suggest modifying the RigBlaster by adding a transformer to break this sneak ground path - if that is possible in this unit (it may not be due to the physical ground arrangement). 73, Don W3FPR > -----Original Message----- > > On Mon, 04 Sep 2006 10:12:47 -0400, Michael E.

Of course, the AUTO/VOX switch >should be in the AUTO position. One other item needs to be noted. In MixW (for those of us who use it), go to Config | TRCVR CAT/PTT and make sure that the serial port used for the RB is specified and enabled and CAT set to "None". When all that was done, everything worked properly. >I don't know how that squares with the Rigblaster instructions, but it is >what their website schematic indicates must be done. It's in there on the last page but it's rather cryptic. The configuration is the one for "PTT on RTS DTR and TXD on KEY" >After looking at the Rigblaster schematic, I am amazed that they >did not include a transformer in the headphone jack to soundcard >connection.

Hmmmmmm <g> I don't think that it's possible because of the way the PCB is laid out. Perhaps the designer for West Mountain Radio could take that into consideration. My RB is fed to the computer through an iMic USB adapter. I don't know if there's any isolation in that, or if an in-line isolation transformer outboard of the RB would do any good. In any event I don't use the headphone jack on the RB.

Hello Group,
I have been using an MFJ-1279 for digital (just PSK_31 for now) and it seems to be very well behaved. External sensors confirm a clean signal. Bit pricy, but well-featured. My question is: Have any of you used the MFJ digital software (RadioCom4 or RadioCom5)? Both are very expensive for software, and I don't want to take a blind risk. They seem to offer everything but fresh grilled cheese sandwiches. Are they worth the $$$?
