Re: [Elecraft] K3 Digital audio out ?
For noisy speech it's not at all bad. For data modes - write your own seems to be the best option, this is what I plan to do for DM780 sometime. Sending data around at 8kHz with (estimated) 25% overhead is not a big problem, it's a trivial programming task, just takes some time to design and the implement it properly.

Re: [Elecraft] K3 Digital audio out ?
Hi Julian et al., I might have found a cheap and easy solution providing a full remote access to the K3 via a local network and/or via the internet. I tested a wireless LAN router from Asus (WL500g Premium) at the last weekend. Using a new OS (Open-WRT with X-WRT) at that router will allow you to set up a virtual serial connection to the K3. That works already e.g. with HRD. The router provides two USB-Ports that can be used e.g. for that issue. At the second USB-Port you can use a simple USB-soundcard to stream the audio into the LAN / Internet and vice versa. That's not really tested until now but the Open-WRT OS supports such USB-soundcards. We tested that support already. Now the only problem to solve is how to get the audio back for in-/output e.g. at a notebook-computer (depending on the OS that works at the notebook-computer). We're working on it... Hope to provide exact information within this week (now I got one week off from QRL) :-) 73 de Sascha, DH2SE -- View this message in context: http://n2.nabble.com/K3-Digital-audio-out---tp838886p1077238.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Hi Sascha, For audio there's SKYPE and IP-Sound. Take a look at http://forums.ham-radio.ch/forumdisplay.php?f=46 for a lot of remote radio discussions. I'm currently working on a remote EME system with a nice 10m dish (not mine), the whole station will be controlled using HRD and my new satellite software. http://www.radiosky.ch/home.php I may even write a remote audio solution for radio use - not sure yet. We will be able to power up / down all components remotely, can hear own signals about 12dB above the noise on 23cms using EME and that's when we don't even shout! 41dB gain on 23 cms, 30dB (I think) on 70 cms. We have a complex rotator system and with so much 'stuff' at the remote shack a PC is essential. Not a single Elecraft product in sight (yet) but once it's all working I may well put my K3 there with a vertical for 20m or something...

Re: [Elecraft] K3 Digital audio out ?
Hi Simon and Julian, thank you for your support. I'd also appreciate that if such a signal would come out of the K3. Others (IC-7700 et al.) support that too, sometimes via USB or ethernet. I'm not happy to digitalize the analog line out audio signal external into a PCM stream by using e.g. a microcontroller because of the additional signal propagation delay of the ADC conversion. For using the K3 as a remote TRX it is nowadays not state-of-the-art to let a PC run all days long. A modified wireless lan router is less expensive, regarding its power comsumption. I already thought about using a wireless lan router w/ integrated VoIP port (where you an plug in an analog telephone) to plug the line out and the line in port of the K3 to this device by using an telephone-interface to solve that problem. That could provide a audio connection e.g. via skype to the K3 from all places, if you want even by using a standard telephone line to call the K3 from every fixed line or cell phone.

Re: [Elecraft] K3 Digital audio out ?
Julian, I have the same problem using the K3 wireless around the house e.g. while sitting in the garden. But I need also the possibility to use the K3 from far away. Bluetooth is suitable if you use a Jabra A-210 Module for the audio transmission directly to a headset and a second Bluetooth dongle in combination w/ a serial to usb converter for the data to a PC / notebook computer. I used this already but unfortunately, the range of Bluetooth Class 2 or 3 gadgets is not very nice (less than 30 ft.). But I there is a supplier for a Bluetooth modul which supports Class 1, I'm working on it. I do have access to a embedded system that comes with a ARM7 µController. I should be possible to run an embedded Linux at that device. It would have all necessary ports (2x RS-232, USB (the protocol is already implemented), Ethernet (the protocol is already implemented), native UART's). The size of that board is only 800 x 300 mm (31,5 x 11,8 inch.). The price is less than 100 €. That should fit into the K3 with no problem. The only thing is: I do not have the time to develop it using Linux or a custom made firmware :-( Getting retiered is estimated by the year 2038. 73 de Sascha, DH2SE ...Timewave has released a gadget that provides full access to the radio using Bluetooth, but inevitably it can be used only under Windows. :( ...develop a something based on an embedded Linux board, to present a web based interface to the K3 with streaming audio.

If I did, I'd go for an external box that plugs in to the RS-232 port and line in and out jacks on the radio side, and ethernet on the other. You'd need an on-board sound card, of course, to digitise the audio. Using Hamlib for rig control, the device could work with any radio, so the market for it would be much bigger than just the K3.

Latency of 10 msec can be too much in many sound systems. There are MANY products that will do an A/D and D/A conversion in a total of 2.4 msec. The MAJOR source of latency for remote control is the internet (or telephone system) path between the remote site and the control point, which can be several hundreds of msec. 73, Jim Brown K9YC ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
