Karsten Eppert(DK4AS) wrote: Hi, have elecraft ever considered an adaper for the k2 to drive an oszilloscope as bandscope? Could be a helpful aid at least for people running the VHF-transverters. 73 Karsten DK4AS Karsten, the answer may be even cheaper. There is on going development in the ham radio circles with Software Defined Radios, or SDR. Look at this web site for a $ 28.00 kit you can build: http://www.hamsdr.com/login.aspx (create a new user with the new user button below) Some pictures of one built: http://www.tracey.org/wjt/sdr1k/SoftRock40/SRV5-pics/ These little boards give you a 40 or 20 meter receiver, with a moderate bandwidth (depending on your sound card). I use an external M-Audio Transit, which has 96 kHz sampling, and plugs in via the USB. My thought on this little unit is to get a crystal for 4.915 MHz, and tap the IF of the K2, and then monitor the bandscope on the computer. I just haven't gotten time to modify one of the two units I ordered. I was rather stunned when my wife and I walked in the Holland, MI club meeting last Tuesday night, and fellow K2'r Dave, WD8PUO had brought his $ 28 SDR kit to the club for a show and tell. Is any one else on the list experimenting with this SDR as a bandscope for the K2?

Re: [Elecraft] Bandscope
This program suite is a winner, and it's FREE. The PSK software is spectacular! I've been using it for more than a year.

Re: [Elecraft] Bandscope
It looks pretty, Jim, I'll grant it that. But MixW supports many more modes, plus rig control and logging, and all from within one application that needs less screen real-estate. It isn't FREE, but at fifty bucks it's still a lot less than most ham radio products. 73, -- Julian, G4ILO (RSGB, ARRL) G4ILO's Shack: http://www.tech-pro.net/g4ilo Jim Brown [EMAIL PROTECTED] wrote: This program suite is a winner, and it's FREE.

Re: [Elecraft] Bandscope
Julian, I run both at the same time. Either MixW plus HRD, or MixW plus N4PY. I'll have to try your bandscope. N4PY lets you do cat through a software interface, from MixW to N4PY software, and back again. 73, Chas At 09:52 AM 1/26/2005, Julian, G4ILO wrote: It looks pretty, Jim, I'll grant it that.

Re: [Elecraft] Bandscope
How do they not fight over the serial port? I loaded HRD, then loaded MixW, and it crashed with an illegal instruction. I closed HRD and then loaded MixW on its own, and it worked fine. My bandscope was slightly better behaved: it reported Error opening COM port when HRD was running. I guess N4PY is providing a virtual COM port for the other apps to use. 73, -- Julian, G4ILO (RSGB, ARRL) G4ILO's Shack: http://www.tech-pro.net/g4ilo Charles Greene [EMAIL PROTECTED] wrote: Julian, I run both at the same time.

Re: [Elecraft] Bandscope
Julian, You have to use a separate serial port for MixW PTT/CW and HRD CAT. HRD uses the serial port connected to the K2, and MixW has no CAT. MixW uses the secondary PTT/RTTY port for PTT/CW and the DTR/RTS from this port are connected to the PTT/CW keying interface. CAT is disabled, and MixW has no CAT connection to the K2. On N4PY, you setup the N4PY program to use the K2 with the Pegasus interface. You tell MixW under configuration/CAT to use the Ten-Tec Pegasus. A window opens and you enter the path to the N4PY program. Frequency/mode commands are sent to the N4PY program which send them to the K2. The N4PY program sends the same from the K2 back to MixW, so MixW will track mode/frequency. You still have to use the secondary PTT/RTTY port for PTT/CW. The K2 can use CAT for PTT, but the N4PY program doesn't do CAT PTT. The best way to do this is to use separate directories for each configuration of MixW. One for MixW using its own CAT, one MixW for HRD and one for MixW with N4PY. You only have the full features of MixW when it does its own CAT. The Align function, for example. I set up MixW to send every function the K2 will take, using macros. When using psk31, I like MixW all by its self. For CW DXing, N2PY is the best, as you can get the K2 to do some things it won't do by its self, like have the filter settings follow VFO A or B selection. I will try your program shortly, and see if I can get it work with MixW using one serial port. 73, Chas At 01:29 PM 1/26/2005, Julian, G4ILO wrote: How do they not fight over the serial port?
