Tnx Fred for the feedback. Good info. N2TK, Tony -----Original Message----- From: Fred N. van Kempen [mailto:[EMAIL PROTECTED] Sent: Sunday, May 06, 2007 7:25 PM To: N2TK, Tony; [EMAIL PROTECTED] Cc: Elecraft Subject: RE: [Elecraft] Digital advice sought for K2 and K3
Tony, I'm using a RigExpert S/D with my K2/100. Currently with just the SPKR and MIC connections for audio (which is messy), and hopefully using the MiniDIN on the BLQ interface as of sometime this week (thanks Doug !) - just to make for simpler cabling. The RE is nice, small, and USB-based. That's good for laptops that no longer have a (real) serial port. It also implements its own sound card, _and_ it presents a "CAT" serial port to the various HAM programs. Meaning: - one cable between that box and the K2 for audio/ptt (MiniDIN, or the MIC/SPK setup) - one cable between them for CAT (to the RS-232 port on the K2) - one cable between the box and the PC (USB) That is all. I use it with HAM Radio Deluxe, MixW2 and EchoLink.

I got one of those boards from you so I am set with that. Well that will be neat that I don't have to buy any other hardware for the K3 to operate Digital. So I would only need a program for the PC? And sounds like my Rigblaster will do what I need for the K2. Do I get any advantages by upgrading to something like the Navigator or RigExpert for either the K2 or K3 as an interface? 73, N2TK, Tony -----Original Message----- From: Don Wilhelm [mailto:[EMAIL PROTECTED] Sent: Sunday, May 06, 2007 7:02 PM To: N2TK, Tony Cc: Elecraft Subject: Re: [Elecraft] Digital advice sought for K2 and K3 Tony, As I understand the K3 you won't even need the RigBlaster, it can connect directly to the computer (only cables and plugs needed) - even does RTTY/PSK31 without the computer at all if you want. For the K2, you should provide some isolation between the computer and the K2 - transformers in the audio-out and mic-in do that job and a voltage divider is needed in the mic input because the soundcard output is much greater than the mic input level. The RigBlaster should provide that isolation. Then if you want automatic transmit/receive, you need a transistor keying switch to turn transmit on (PTT) from the digital computer application - easily accomplished with a simple transistor switch to drive the PTT line - Google on PSK31 and you will find a lot of information about how to hook things up. Of course, your RigBlaster includes many of these things, so you may just want to unpack it. If you want a fixed audio output level from the K2, I have a few boards left (no kits) - you can take a look at my website article about it at http://w3fpr.qrpradio.com 73, Don W3FPR N2TK, Tony wrote: > I finally am going to get on the digital modes.
