PSK 31

Hello all: Getting ready to set up PSK31 on my K3 following the operating tips outlined by Wayne. He states: "It is usually best to use a second sound card for...digital modes". Is he referring to something like Tigertronics?

I use a MicroHam microkeyer 2 with my K3 and have a Microham USB 3 for my FT920. Both work great! Very nice products.

First let's explain what Wayne meant: If you use a secondary sound
card/device, you won't accidentally transmit an operating system sound (many of which are musical). You also won't have to constantly twiddle with levels as you switch from OS to the radio. And it allows you to have the computer alert you to DX or whatever you have it set to do, without transmitting that sound, while you're operating in a digital more (the computer is quite capable of having two or more sound cards at the same time). I use a SignaLink (Tigertronics). But there are far cheaper and expensive options, including one I recently saw at another shack that cost a whopping $5.78 after tax and shipping. It failed from structural weakness (SMD connector broke from the board, overstressed) but it did work before that. So between $5 and whatever the fanciest device costs is what you'll pay. They all work, but you'll likely want a little more quality than the cheapest. Jim Brown has done a study of several models and can list some potential watchouts (poor bonding, pin one issues etc) so maybe he'll chime in here. The bottom line (to me) is that you have a serious radio, you're building a serious station, why diddle around with being cheap on a critical part, the sound card by trying to multiuse the computer sound card. That's like putting retread tires on a sports car. ;o) 73, Rick wa6nhc -----Original Message----- From: william wade Hello all: Getting ready to set up PSK31 on my K3 following the operating tips outlined by Wayne.

First, I have SignaLink and microHAM as interfaces between rig and computer.
I like microHAM because it also reads the rig mode and frequency without needing a second USB port. (I also have older microHAM units that need a separate sound card port) I patch direct (now) with my KX3 to the laptop. I do PSK31 and low level modes like JT65. Something to think about if you want to do the low level modes is how GOOD is the sound card. 24 bit and 48K with >100db SNR would be good for JT65 (not required). Keeping system sounds away from the rig is important. I just purchased another sound card ~$25 (USB) for the laptop and JT65 so I CAN also hear (system sounds) the announcements for JT65 Alerts when NEW countries "pop" up... Specs were weak but I am hoping it is 24 bit... You CAN turn OFF all the system sounds and use a single sound port. Useful IF the computer is single use. 73, steve WB3LGC -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of Rick Bates Sent: 27 July, 2013 1:36 AM To: 'william wade'; [hidden email] Subject: Re: [Elecraft] PSK 31 First let's explain what Wayne meant: If you use a secondary sound card/device, you won't accidentally transmit an operating system sound (many of which are musical).

I recently downloaded FLdigi 3.21.72 to my XP32 computer and have my
K3/10 set up using the external emu0202 USB soundcard I bought originally to go with my LP-Pan panadaptor (SDR). The emu has manual level controls which makes set up changes easy when going between different sw. I also have M-Audio Delta-44 four port soundcard that I only use for receive when doing diversity reception. I has a card that installs in the computer and interface unit which uses a sub-D15 cable. The Delta-44 is mainly used for dual-pol adaptive reception on 2m-eme. I have the partially failed internal soundcard disabled. I will be making a "maiden cruise" of psk-31 this evening for a sked at 2200 AKDST (0600z) on 7070 KHz running 12w to an inverted-V. FLdigi seems to be working well on 14.070 in both psk-31 and CW. (Yes, I know this non-std freq on 40m for psk-31). 73, Ed - KL7UW http://www.kl7uw.com [hidden email] "Kits made by KL7UW" ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

I was using the computer sound card temporarily for PSK31 and then JT65.
I bought a quality sound card emu 0204 for use with LP-PAN. I hooked it up to try it for digital modes and the results were significant for weak signals. I could dig 3-6 db further into the mud for weak signals with the much better sound card. It didn't make much difference on strong signals, but it brought in a whole lot more workable weak signals. I now have a SignaLink as I needed the 0204 for the panadapter. I think the 0204 still has a very slight edge, but I haven't really done any extensive testing. Both are far better than what came with my Dell desktop. I agree with your advice. You have a great receiver to pull out weak signals. Now get something comparable to translate them. Get something decent to begin with, then move on to something else to worry about.
