[digitalradio] ethernet or wireless
I can either use CAT 5 wire - about 20-25 feet long - to connect my Ham computer to the internet, or I can turn on the wireless feature of my router and connect via the slower wireless portal. Speed won't be an issue - until I try computer control. Will running the long ethenet cable behind my rigs cause more or less problem than going wireless? Thank you and 73, Paul
Re: [digitalradio] ethernet or wireless
The only problems I experience ,other than speed, are the router occasionally freezing up and needing a power off/power on fix.

Re: [digitalradio] ethernet or wireless
We have excellent experience with using wireless, even in high power multi/multi setups. You will get less noise. 2/5/11 MB speed is more than enough for computer control... 73, Rein PA0R (TS7N, CT9L, 5A7A) -Ursprüngliche Nachricht- Von: digitalradio@yahoogroups.com Gesendet: 14.07.07 11:30:42 An: digitalradio@yahoogroups.com Betreff: [digitalradio] ethernet or wireless I can either use CAT 5 wire - about 20-25 feet long - to connect my Ham computer to the internet, or I can turn on the wireless feature of my router and connect via the slower wireless portal.

The speed wont be an issue as your wireless connection will be MUCH faster than your internet connection. Also consider this: Last year a tree in my yard got hit by lightning. It went into the ground and got my telephone line. Followed the telephone line to the dsl modem and thru the ethernet connection to my computer. Bye Bye computer. Now I use wireless so there is NO connection to my computer. I also now DISCONNECT the telephone line from modem when storms are in area. Stan k9IUQ

Re: [digitalradio] Re: 141A ALE FAE mode
Hello Rick, MFSK16 which requires even more accuracy I think I read in the help files, 4 Hz Yes (and MFSK8: 2 Hz...which becomes a problem). However you can use the 2 vertical traces in the waterfall displayed at the beginning of each MFSK16 transmission. Simply make coincide these two traces with the two vertical fix lines and it will be OK. A RS ID solve also the problem, as there is an automatic tuning. On thing that would help us is some kind of measurement to tell us when we are locked on the phase/frequency OK, similar to the way the earlier programs displayed the graphic phase meter on screen when we operated PSK31. It will be theoritically possible by measuring the difference of phase (after some time as it is MFSK and not BPSK) between the selected carrier and the carrier received but I'm not sure it will be very reliable and surely not on weak signal. By the way, once you do the calibration, is there any way to know that it was done, other than it indicating the offset that it detected? For example, my sound card shows still shows 11101 and 76 Hz offset and does not vary much from that when I run the test each time. I'll see this. Rick: your sound card is rather not very good...Corrections will apply but with an old Creative Labs or equivalent, you will be more confident. 73 Patrick - Original Message - From: Rick To: digitalradio@yahoogroups.com Sent: Saturday, July 14, 2007 1:23 AM Subject: Re: [digitalradio] Re: 141A ALE FAE mode Thanks for the suggestions.

Has anyone running ICOMs with the CI-V had any problem with the rig not turning off transmit sometimes? This seems to happen with my 756 Pro 2 every so often. 73, Rick, KV9U Patrick Lindecker wrote: Hello Rick, Yes, I confirm, you must: * calibrate Multipsk with the sound card installed: click on Sampling freq. then click on Determination of the standard RX sampling frequency... and Determination of the standard TX sampling frequency It is automatic. * Let the AF frequency fixed for ALE (open the Options window) and be sure of the HF frequency (in ALE you can accomodate +/- 15 Hz, no more). You can start with sending AMD messages through the Aux. functions window. Then try to send FAE APRS position.

Also, be sure of your frequency calibration of your transceiver. Bonnie KQ6XA -- No virus found in this incoming message. Checked by AVG Free Edition.

Re: [digitalradio] Re: 141A ALE FAE mode
If the sound card does vary from the ideal, doesn't the correction bring it to the correct point? As long as it is within the required + and minus of 200 or so? By the way, I checked the sound card in my newer HP Computer that is running Vista and the numbers are almost exactly the right ones. In fact, on one test the number was 11025 for the sound card sampling rate. I may have to try out this machine again for my ham activities. Normally, I use a 2.93 GHz emachines computer running XP for that purpose, but as you note, it does have a mediocre built-in sound card. I actually have a Soundblaster Live! card that is not being used, and maybe I can figure out how to get it to work with my emachine. 73, Rick, KV9U Patrick Lindecker wrote: Hello Rick, MFSK16 which requires even more accuracy I think I read in the help files, 4 Hz Yes (and MFSK8: 2 Hz...which becomes a problem).

Yes the TX and the RX are corrected so as they seem to be normalized at the nominal speed of 11025 samples/sec. However, better is to not have to correct at all (it's a feeling). running Vista and the numbers are almost exactly the right ones. In It is based on the PC cristal frequency. The difference between 2 cristals must not pass 0.05% . I actually have a Soundblaster Live! card that is not being used, and maybe I can figure out how to get it to work with my emachine. Surely it is worth to test it. 73 Patrick - Original Message - From: Rick To: digitalradio@yahoogroups.com Sent: Saturday, July 14, 2007 9:23 PM Subject: Re: [digitalradio] Re: 141A ALE FAE mode If the sound card does vary from the ideal, doesn't the correction bring it to the correct point?
