Re: [Flexradio] Sound card input Voltage
Usually for audio applications dBm should be referenced to one milliwatt into a 600-ohm load. (Your dBm figure is using 50 ohms). In order to avoid confusion when we're measuring voltages, it's better to not use dBm at all. For voltages, it's probably easiest to use dBV referenced to one volt RMS. (There's also dBu which is equivalent to dBm @ 600 ohms.) To answer your original question, while the Delta 44 may not be a typical sound card, its input range (peak-to-peak) seems to be 11 Vpp. That's about 5.5 Vpeak, 3.9 Vrms, +12 dBV (+14 dBu). The maximum input level is 6 dB lower when using the consumer setting in D44's control panel. And using the lowest setting means another -6 dB. That would be 0 dBV == 1 Vrms. Maybe that's pretty close to a typical (cheap) sound card. 73, Sami OH2BFO On 4/15/07, k5nwa [EMAIL PROTECTED] wrote: What is the full scale input to a typical sound card?

Re: [Flexradio] 2 radios
It depends on whether or not the drivers adhere strictly to the ASIO SDK 2 rules. There can only be ONE ASIO device in a system that adhere strictly to the rules. There is an alternative that needs further investigation. Bob N4HY Lee A Crocker wrote: I know the firewire will handle more than one thing the question is can the same drivers be active at the same time and identify each radio uniquely. I'm sure it can be worked out. The firebox drivers are so anal that they won't even allow a firebox card to be swapped out for another firebox card without uninstalling and reinstalling the drivers.

Re: [Flexradio] SDR 5000 advice needed
Hi Phil, I am one who never purchases version 1 of any product especially computer software and hardware. That said, I believe you should monitor the reflector when the new product is released to see what problems if any are being reported. I'd say wait at least 3 months but no more than 6 months (ballpark figure based upon gut feeling). Also note that demand for the new units will be high and it may take some time after you make your decision to actually obtain one. Additionally, most problems are immediately adressed by Flex so if you do encounter a problem your resolution will not be far behind. Hope I helped!

Re: [Flexradio] SDR 5000 advice needed
I can understand some folk's reservation about waiting for the 2nd or 3rd production run of the radios before buying one, but history shows that FlexRadio is much different than other hardware manufactures. When the SDR-1000 came out, there were various ECOs that corrected problems. You could send in your radio and get the fixes that matched the production units being sold at that time, so your risk for getting a version that is not like later versions is just about nil. Mine was purchased 2.5 years ago and it has all of the changes (sans the RoHS board) so that is identical to the last ones produced. As far as software is concerned, if you are using the SDR-X code, you are already running the same code that will ship with the FLEX-5000. You are just not using the F5K specific hardware code, which I am sure, will be well beat up by the beta testers before they ship it after Dayton. I plan to have one in my shack in June. -Tim -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Edwin Marzan Sent: Sunday, April 15, 2007 12:50 PM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subject: Re: [Flexradio] SDR 5000 advice needed Hi Phil, I am one who never purchases version 1 of any product especially computer software and hardware.

Re: [Flexradio] Sound card input Voltage
Thanks everyone for the answers, I suspected I had it wrong and I did. I have an output in dBm at 50 Ohms, using a transformer to convert the impedance from 50 ohms to 600 Ohms then output in DBU would be the voltage at 50 Ohms times the square root of the impedance ratio or 3.46 times higher than the 50 Ohm ? +14 dBm = 1.1V at 50 Ohms convert to 600 ohms with a transformer and you have 3.8V at 600 Ohms or 10.7V PP +26dBm gain prior to that and I end up with -12 dBm input or higher will start getting you in trouble. Anybody know where I can find a sound card with 180 dB dynamic range for less than $200?

Anybody know where I can find a sound card with 180 dB dynamic range for less than $200? If there was one, we would all have one. :-) -Tim, W4TME -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of k5nwa Sent: Sunday, April 15, 2007 1:56 PM To: Sami Aintila Cc: [EMAIL PROTECTED] Subject: Re: [Flexradio] Sound card input Voltage Thanks everyone for the answers, I suspected I had it wrong and I did. I have an output in dBm at 50 Ohms, using a transformer to convert the impedance from 50 ohms to 600 Ohms then output in DBU would be the voltage at 50 Ohms times the square root of the impedance ratio or 3.46 times higher than the 50 Ohm ? +14 dBm = 1.1V at 50 Ohms convert to 600 ohms with a transformer and you have 3.8V at 600 Ohms or 10.7V PP +26dBm gain prior to that and I end up with -12 dBm input or higher will start getting you in trouble.

In order to avoid confusion when we're measuring voltages, it's better to not use dBm at all. For voltages, it's probably easiest to use dBV referenced to one volt RMS. (There's also dBu which is equivalent to dBm @ 600 ohms.) To answer your original question, while the Delta 44 may not be a typical sound card, its input range (peak-to-peak) seems to be 11 Vpp. That's about 5.5 Vpeak, 3.9 Vrms, +12 dBV (+14 dBu). The maximum input level is 6 dB lower when using the consumer setting in D44's control panel. And using the lowest setting means another -6 dB. That would be 0 dBV == 1 Vrms. Maybe that's pretty close to a typical (cheap) sound card. 73, Sami OH2BFO On 4/15/07, k5nwa [EMAIL PROTECTED] wrote: What is the full scale input to a typical sound card?

Re: [Flexradio] 2 radios
I don't have a clue, but they software was treating it as live video and kept track of dropped frames and there were none. My son was very anti-Mac but he was having problem doing professional quality videos without dropping some frames, I put this demo to test the systems and show him that at the time (middle to late 90's) if he wanted to do decent video he needed to do it on a Mac and use my Firewire drives to store the videos. After that demo he ate crow and asked if he could have one of the 8500's, he had no dropped frame issues after that. The moral is that Firewire when implemented correctly is awesome for high data rates with data that is time sensitive, that was the purpose behind it when Apple invented it in the first place. Something is not quite right with the Windows implementation, I notice a huge transfer rate difference between my Mac and my PC's running Windows using the same drives, cables, and interface cards. I also noticed that when transferring a lot of data, if I ask for a second set of transfers at the same time, the Windows PC chokes on it, while the Mac does not, something is not quite right in Windows.

Audio even at 192KHz is nothing compared to the video streams. Disclaimer: that was on MAC's, they handle video like a duck takes to the water, these were however very old Mac's, 8500's with 350MHz G3 CPU's. But isn't this a packet system in which the data goes in packets with error-checking on each batch? If this is true then when a glitch occurs the system stops and gets another copy - the system could slow down to a crawl and the data would still get through eventually, but might NOT be happening at the video's real-time data rate speed. You don't want pops and lapses in the audio coming through if you are actually listening to it rather than simply transferring a file.

[Flexradio] ASIO multi
I use N1MM. The CAT uses TS-2000 emulation, so if Logic-8 can control the TS-2000 it can control PowerSDR. If it can control 2 x TS-2000's it can control 2 instances of PowerSDR. Control of the PTT and radio is through the serial lines provided by a program called VCOM. These connections are between PowerSDR and N1MM not between the actual radio hardware and N1MM. The radio hardware is controlled by PowerSDR through the firewire. This is an important concept to get your mind wrapped around. It is the software namely PowerSDR that communicates with the CAT interface not the hardware. I use 2 seperate sound cards the FA-66 and the Firebox both daisey chained on a single firewire connection to the computer. So the real issue is what Bob addressed how can 2 sets of the drivers for the new radio uniquely control 2 radios. I would think a SDR-1K with a soundcard, and a Flex 5K would have no trouble co-existing on a single firewire, running 2 instances of PowerSDR. 73 W9OY __ Do You Yahoo!? Tired of spam? Yahoo!

Re: [Flexradio] IZ8BLY Stream and Hellschreiber
Hi Brian, the unanticipated Host error often relates to mismatched sampling rates. Make sure the sampling rate and mono/stereo settings in VAC (through PowerSDR)and your digital software are the same. Some digital software (HamPal, eg) will only accept stereo 48kB/s.

Re: [Flexradio] IZ8BLY Stream and Hellschreiber
Brian, Also recommend an upgrade of VAC to the latest version 4.04. The latest VAC version is more tolerant of mismatched sampling rates. I notice that you are using VAC 3.12.

[Flexradio] EDIROL FA-66 microphone input problem ?
Hello, I finally tried hooking a microphone up to my new EDIROL FA-66 soundcard. I followed the suggestions in the quick start guide in the KB. I connected a mic with a 1/8 mono plug to a 1/4 in TS adapter plug and put it into input #1 on the FA-66 but got no output. I next tried recording an audio signal from the mic to Audacity but could get nothing through the EDIROL. I can get an audio signal from the mic to the laptop soundcard and then to Audacity. I also tried the mic on my Heil headset but still no luck through the EDIROL. Do I need to use a balanced XLR audio plug?Any ideas?

Re: [Flexradio] EDIROL FA-66 microphone input problem ?
I wired a Shure 450 desk mic to a 1/4 plug so I could plug it directly into the breakout box of a Delta 44. I clicked on the MOX control and like you didn't get any audio. I didn't until I locked the PTT bar on the desk mic. All is working well now. If you are using a mic with a switch maybe it needs to be locked on. Marty KG6QKJ At 07:26 PM 4/15/2007, you wrote: The input 1 on the FA-66 will take either an unbalanced connection (1/4 TS) and balanced (XLR or 1/ TRS) connector. A balanced connection is usually preferred when connected to the FA-66 for a low impedance microphone.
