Then executed a pktloss test. No errors. Great, lets move on. I put the cables back and went to roof. Now I want to make pktloss test on a loop with rx and tx - one side of link. I have extracted rx and tx modules from tubes and oriented it one to another. pktloss test is running the whole time, but my pc screen is far downstairs.... if I could only have someone to help me, or something. Well there is a thing! There is linux software called espeak. There is my PMR with charged bateries :) So I started two shells and in first executed: #./pktloss | awk '{ print $2, $3 | "tee -a /tmp/a.txt" }' and in second while true; do tail -n1 /tmp/a.txt | espeak -p30 --stdin --stdout | aplay sleep 1 done why so complicated? There is some issue with espeak and stdin/out redirection so this is what I got working :) Now pktloss is running, and espeak is reading just second and third column output which represents loss. I put my PMR with "constant send button" near my PC speakers and hurry to the roof again... I turned ON my second PMR and adjusted rx to tx little better and from the PMR there was the computer voice: zero, zero (1 second pause) zero, zero... etc. Now I know my side is fine. I placed modules into the heads again... PMR says: one hundred dot zero zero, one hundred dot zero zero ... which means 100.00 % loss on both frequencies ... So what is wrong? .. after all this years... there is a brand new building.. in a path of course :))))))))))) Wish you all the best, old friends... silvije From tpreitzel at hotmail.com Mon Jun 28 23:38:14 2010 From: tpreitzel at hotmail.com (TP Reitzel) Date: Mon, 28 Jun 2010 22:38:14 +0000 Subject: [Ronja] Mass Production Message-ID: Hi, The title basically makes my point. Is anyone mass producing this system? If so, who including addresses and telephone numbers. If not, why not? I fully realize that line of sight limitations limit the appeal of optical systems, but optical systems do have advantages, i.e. minimal regulation and interference from governments. How much (USD) would a pre-built RONJA link (Tx/Rx) cost currently and if mass produced? I fully realize this list deals specifically with the RONJA system, but many people have very busy lives and would prefer to buy a complete link. Lastly, will this optical system be updated with current electrical components, i.e. more powerful LEDs, etc? -------------- next part -------------- An HTML attachment was scrubbed...
