K3 - K3/0 Installation
Locked
 
|
Due to local CC&R's I am thinking of doing a remote station installation and
was wondering what the experience has been using the K3 and K3/0 in a remote station application? What was your opinion of the installation and was it suitable for contest operating? Would a normal DSL internet service be sufficient?

My experience is that the K3/0 makes the remote station completely transparent. It is just like being in front of the rig. I have the K3 plus a SoftRock/soundcard on the IF output using the SpectrumLab client server application to provide a realtime waterfall display. The complete system runs about 900 kbit per second the way I have it configured - the remote end of the link has a 1 Mbit capacity, the local end about 40 Mbit/sec.
What you will notice are dropped and delayed packets on both the audio and data side of the radio. If the internet providers on either end of the link are having a bad day, you will notice it (for my carriers, it doesn't happen very often). Installation was easy - follow the instructions. It is best to set up the K3, K3/0, and the remoterigs in the same room the first time you do the configuration - builds your confidence that it is really working. I have had problems with older stock routers that have a limited number of port forwarding slots, I have had good success with the WRT-54 using DD-WRT. I have operated several VHF and 10 meter contests using the K3/0. At 25 wpm CW, it works fine, either running or S&P. I haven't tried it any faster. Typical tracert and pings on my system show 12 or 13 hops and times of16 to 23 milliseconds. If you had to use a satellite link with their much larger delays, your results could be significantly different. 73, Mike, W3IP --- On Sat, 3/9/13, Roger Huntley <[hidden email]> wrote: From: Roger Huntley <[hidden email]> Subject: [Elecraft] K3 - K3/0 Installation To: [hidden email] Date: Saturday, March 9, 2013, 6:43 PM Due to local CC&R's I am thinking of doing a remote station installation and was wondering what the experience has been using the K3 and K3/0 in a remote station application?

Does traffic OUT of the K3/0 dominate that 900 KB/s stream? Have you
measured the in/out components on either end?

The RemoteRig has many options for audio quality and bit rate. This can range for 8 KHz/8 Ksamples to 16 bit/16 KSamples. You can choose half duplex or full duplex. Right now my local router is reporting
Incoming bit rate in receive: 125 Kbit/second I use 8 KHz/12 bit sampling which accounts for 96 Kbits of the data The command and control info and the packet overhead accounts for the rest Outgoing bit rate in receive (no changes): 2 Kbit/second Status requests to the remote K3. Outgoing bit rate in receive (spin the main tuning knob of the K3/0): 50 Kbit/second In transmit, the incoming and outgoing data rates are swapped. Spectrum Lab can also be configured to provide data at different rates. Right now I am requesting data from the remote Spectrum Lab web server every 2 seconds. When the load from Spectrum Lab is added, the incoming data rate jumps from 125 Kbit/second to ~400 Kbit/second. The outgoing data rate bounces around a bit, but averages about 8 Kbit/second. Does that help? 73, Mike, W3IP --- On Sun, 3/10/13, Rick Tavan N6XI <[hidden email]> wrote: From: Rick Tavan N6XI <[hidden email]> Subject: Re: [Elecraft] K3 - K3/0 Installation To: "M Cresap" <[hidden email]> Cc: [hidden email] Date: Sunday, March 10, 2013, 5:52 PM Does traffic OUT of the K3/0 dominate that 900 KB/s stream?
