Bob,
I am using also Sling from time to time for my parents when they are visiting me in Canada from YO land to watch local programs in Romanian and on my end I am using a Slingcatcher (RX-er), the stream from Europe to here (on Rogers Network) is abt 1.5Mbps, not too bad but delay is around 160msec. A good idea is to think to set-up QoS on your routes on both end (I hope the providers infrastructure are forwarding qos tags also otherwise is a waste of time) to eliminate the possibility of adding additional delay in your remoterig (SIP) voice packets. Now I am experimenting different mikrotik (router) configuration setup adio sip server with highest priority- Voice (same with CW key packets) and rig control as Video priority (one step lower) . Sling is eating lots of bandwidth so gotta be configured with best effort (lowest priority) otherwise lots of additional delay will be added to existing one. I am planning to try a remoterig from my overseas shack here in Canada with the beautiful K3/0 solution, but still in experimental phase with routers configuration, mikrotik routers are linux based, very complex and requires deep networking knowledge. There is a long discussion how to configure the beasts, UDP packets, size of the packet, rate control so and so...not an easy task. Would be nice in the future Elecraft to take one step forward and to integrate remoterig into K3/0 eventually to sell a compete solution including routers already preconfigured for best performance, I know this will be faar away from their main core business but I see IP integration into hamradio world moving forward faster than we think. On youtube there is a clip with a remoterig over 3G network from mobile, so in the near future this kind of integration won't be considered so exotic.

Now that remote controlling the K3 is easy with the RemoteRig device and the new Elecraft firmware, I’m headed down that path. However, the current state of most devices makes remote viewing of my P3 pan adapter a challenge and Elecraft has not addressed this as yet. After experiencing the value of a P3 for the last year I miss it terribly when I’m at my remote location. To date it has been difficult for me to view most waterfall displays remotely due to the high bandwidth requirements of the ever changing picture. I’ve tried remote viewing of many PSK-31 displays with poor results. The bottleneck is usually the low upload speed of my consumer Internet circuits which are cable at one end and DSL at the other. Their upload speeds are 1-megabit or less and remote control programs such as Microsoft's Remote Desktop, PC-Anywhere and VNC just don't compress the video enough for a satisfying result and it locks things up waiting for each new frame of video. However, MPEG4 does a nice job of transmitting my local news in standard definition NTSC at about 500 kilobits/sec. So, I’m going to try that method for my P3. I haven't tried this yet but I'm gathering the parts for the experiment and I should know more after I visit my P3 at the remote location and wire things up. Unfortunately that won’t be for over a month and this is not of interest to my adult children who are there to kick most other things when needed. If anyone else wants to try this before I do, I’d be very interested in your results. I have an old Slingbox Classic that I use to send local, over-the-air television to Hawaii so that I can watch the local Seattle news from here. This unit accepts video via an RCA or S-Video connection as well as having an NTSC tuner. They don’t offer this older unit any longer but their newer offerings include the PRO & PRO-HD models which have either no tuner or, in the HD version, an NTSC/ATSC/QAM tuner. SlingMedia.com claims a 400% improvement in video for these newer offerings over what my classic produces. I’ve found an $18 device at Amazon.com (Kanaan PC VGA to TV Composite Video RGB Converter) which claims that it will convert RGB video to S-Video. There are other converters listed so be careful that you get one that will accept video in a resolution that the P3s SVGA card will produce. I’ve chosen 1280 x 1024. This unit should accept the output of the P3’s SVGA card and convert it to S-Video ready for the Slingbox. The SlingBox should then send it over the Internet to my remote location using MPEG4 compression and be ready for viewing on my PC using the SlingBox player that came with my classic unit. The main unknown right now is the latency of the video buffer and how that might impact operating. This arrangement will not allow me to control the P3 remotely but viewing the P3 is primary while control is secondary to me for now. I don’t see why this shouldn’t work but until I can try it I will be looking for comments on how I might do this using any other method someone might be willing to share.
