[Flexradio] SDR Console Peak Power Readings others
I am curious as to what other users get for readings when in SSB transmit mode. I am using Heil Pro Headset with an HC-4 element. Using an Average tone of voice, With no compression or compand mic set to 25 the alc hits the right edge of the meter fairly consistently. Foward Power - I see a peak to the end - on voice peaks a reading of 146 On peak power - I see as many as 4 figures one reading is 8202. These readings dont seem right to me. Can anyone tell me if this is consistent to what you are seeing with your SDR radio? With the previous version of the software 1.4.4 this didnt happen. I am using the latest BETA version for these readings. Stan AH6JR

Folks Well the Belize DXpedition is officially on it's way. Tuesday everyone arrived and our host Bob Fox was very welcoming and helpful, getting us settled in the resort. The afternoon and early evening was spent getting V31SR computer and radio set up as well as dsl modem, wireless router and other gear set up. It is a minor miracle that the AA4SW gear made it. A rugged looking file case containing the entire bare bones station could not be carried on as anticipated, and arrived in Belize with the bottom of the case falling off. Some packing tape at the airport temporarily held the bottom on and nothing was lost, The ATX case was dented. Also the rugged transit case looked 'sucked in' on the sides putting in doubt whethere the LCD monitor made it. Everything did, but it should be a challenge to get it all re-packaged for the trip home. The flight down from Belize City was rather a hair raiser. About 20 folks packed into the plane which seemed a little overloaded. Carson, the last person on sat in the co-pilots seat. The 'airports' are not much more than poorly paved strips only a little wider than a 1.5 lane road! V31LL jumped right on Bob's Kenwood and had a pile up going for about 1/2 hour before we kicked him off the air so we could set up. We were all thrilled to listen to him make many contacts, with anticipation of what is to come. Terry V31TG made a couple of Q's on the SDR-1000 before we all went to 'happy hour' and ate. With all that is going on, I don't know how much time we can spend on messaging or setting up communications sessions, But I will try to get word out and pictures posted over Bobs Internet connection. The 8' x 10' foot shack is not really conducive to setting up 2 - stations and an Internet communications postk, but will do the best we can. Carson and I collapsed after 21 hours of combined travel and set up. More later. Lotsa fun and these guys (including Carson) are the best in the world. It is fun to be around such enthusiasts!

Re: [Flexradio] Ham Radio Deluxe - high CPU rate
For reasons best known to myself at the time I refresh the SDR data very quickly - much more quickly than other radios. I can drop this down, but maybe one of the SDR-1000 CAT implementers can take a look? In HRD you set the polling frequency via the Options - select the Frequency page and you will see the Refresh Interval. If dropping this to 300 while using a Kenwood radio solves the problem then I know what to do - a 20 second change. I don't remember seeing this myself but to be honest doesn't use my SDR-1000 very much at the moment as I am working on HRD so much. Be sure it's the SDR-1000 which is using this extra CPU and not HRD (use the Task Manager to confirm). Anyway you bought the CPU - why not use it :-?

[Flexradio] DXpedition Notes
As noted, I did manage to do some operating yesterday afternoon. Real easy to raise a pileup on 17 M SSB. When the SDRs were set up, tried 40 SSB without success! Bob Fox explained we needed the amp on line just to get started. I'd never done it in the DX range before, but apparently, 40 SSB is very competitive for DX stations. We didn't have the amp in line so I went to supper. After supper, plugged the Bulldog keyer in and tried 40 CW. Not my best and most shining hour. Keep in mind I'd been up at that point for about 20 hours. Did about 25 Qs in an hour's operating time. Not satisfied with my performance. We'll see. If I do it again tonight, I'll probably be on 40 CW in the lower extra part of the band (as close to 7.005 as I can manage). There was a steady stream of US, Euro, some Carribeans. Even had TI8CBT (I think I remember that right, op is Carlos) chasing me. A real trip after I had run afgter him on RTTY at home. However, we may be on 160 instead (that is, someone other than me). We just erected an HF2V modified by V31MD to be 160 only. They just got done rsonating it for about 1830. After supper (about an hour from now) we should have one or two stations on the air. After that, it's anyone's guess as to the next step. Tomorrow, Eric and I get up with my wife and Carson to tour some Mayan ruins. My wife and I snorkelled Laughing Bird Caye today -- tremendous experience, ocean life starts the moment you put your mask in the water. We'll have to see if any of the pictures are any good and see if we can get 'em on CD down here. Got an arial shot from the plane ride Eric described yesterday as my wallpaper. More when I have time. May also try to run up to 7.030 to give you all a chance at 40 CW sometime (not sure when). If I can e-mail from the shack, I'll give a holler here when ready. A lot is still coming together, but it looks very good for the contest. Larry V31LL
[Flexradio] What impedance value does...
Title: What impedance value does... High impedance headphones become high impedance. Yes, it is a strange question. I have recently received my SDR1K, but unfortunately I am in a different hemisphere that the radio. So, I started reading the operating manual (yes, I can't believe it either - there is a first time for everything HI HI) and it states that you need high impedance headphones to connect to the soundcard (a Delta44 in my case). I was wondering at what impedance value headphones become high impedance? Is it 600 ohms or higher?

Re: [Flexradio] CAT Control
I'm sure i'm off base here as I'm not in the same league on this stuff as most. But I recall an issue with the StepIR box that the external program being used need to poll the radio to get the propper commands sent and picked up by the stepir interface. If there is nothing polling the SDR or making the SDR send the sigs thru the com port then the stepir won't know anything has changed. So either the radio has to poll automatically to a specified com port or another program has to make it poll. OKnow I've lost myself. Take a poll..who thinks i've gone over the edge?

Secondly, you might try changing your ID selection on the CAT tab to something other than "SDR-1000". I suspect the StepIR software doesn't know anything about an SDR-1000.

Re: [Flexradio] CAT Control
Tom Thompson wrote: Bob and Bill: I built a SteppIR simulator in another computer so I could interact with the SDR-1000. What is happening is that the SteppIR box is issuing an IF; command which demands a 38 character response. Portmon says that 38 characters are being sent, but only 28 characters are actually put out by the UART and then the CatControl no longer responds. If I send an FA; command, the response is only 14 characters and 14 characters do indeed come out of the UART and the CatControl does NOT die . It continues to respond to the FA; command and the simulator follows the SDR-1000 just like it is suppose to. My gut feeling is that the UART is somehow being terminated before it has a chance to get all the characters out. To check this out, I changed the baud rate from 4800 to 9600 to see if all the characters could get out, and they did. At 9600 baud, the IF; command worked fine with the SDR-1000. I then changed the SteppIR box to 9600 baud, but I do not have that working yet. In summary, I think what is happening is the UART is getting shut down before all the characters are dumped. I have had this happen in assembly language before, but I don't know whether this is possible in this case or not.

Re: [Flexradio] CAT Control
I think what youre asking is: How does the StepIR box know that the frequency has changed? The answer to this question, as I understand it, is that the box itself sends a CAT command to the serial port from which it is expecting a response which includes the frequency.

I have no means of testing it other than with my SDR-1000.Lookingat the code, I can't see any reason for it not to work in real mode.Meanwhile, the CAT tester does not interface with the serial port, itinteracts with the console software directly so it is no indicationthat theport is working.

Re: [Flexradio] What impedance value does...
Title: What impedance value does... Hello Tim, I think 600 ohms would be considered 'high impedance' these days. However, since the Delta44 card has two L-R pair of outputs, one pair for driving speakers (through an external amplifier) or headphones (direct, or through an external amplifier), and the other pair to drive the SDR-1000 hardware during transmit, you don't have to be concerned about your headphones loading down the soundcard output and reducing transmit power. This is a concern with the Turtle Beach card and any other card that has only a single stereo output, such that the headphones are essentially in parallel with the SDR-1000, but it is not a concern with the Delta44. 73, Dale WA8SRA Tim Ellison wrote: High impedance headphones become "high impedance". Yes, it is a strange question. I have recently received my SDR1K, but unfortunately I am in a different hemisphere that the radio. So, I started reading the operating manual (yes, I can't believe it either - there is a first time for everything HI HI) and it states that you need high impedance headphones to connect to the soundcard (a Delta44 in my case). I was wondering at what impedance value headphones become high impedance? Is it 600 ohms or higher?
