[Flexradio] RFE BOARD QUESTION
How do I set 'XVEN' signal to logic '1' (+5v) to energize relay K12 on the RFE board. I have tried checking XVTR Present (the logical choice) on the SETUP/Hardware Config panel, then also tried selecting VHF, 2M and setting VFO A to 144.2. XVTr panel settings are good since I was able to run the SDR with my HB transverter before installing the RFE board. Also tried selecting Positive, Negative and NO TR logic settings. Phil, K3IB
Re: [Flexradio] Steady drop in output power with successive Previews.
Bob Eric, Bob, I tried the use of the CPDR with poor results. At the second lowest setting of the CPDR (2 db) the audio quality was degraded significantly introducing a lot of distortion. At the lowest setting, (1 db) the distortion was less, but still very prevalent. At these setting, there was no difference in RF power output between using CPDR and not. I did the same test using just the COMP and the results were similar, but I had to use higher values (4 2 dB respectively). Even at 1 dB there was still noticeable distortion. Using the TX EQ did help some, but I had to add a lot of gain to make a slight difference and adding that much gain resulted again in a distorted audio signal. So I tried some more testing... Using a PSK steady tone (carrier only), I set the output gain until I was showing 50 watts Peak and Avg. power output (1/2 of the rated value of the PA). I used this value to calibrate my non-peaking reading watt meter. I also verified this with a CW carrier and they were very close. With the MIC setting peaking at 0 dB, the RF output is just 20 watts. The Peak power meter showed a max peak of 46 watts. I have a true peak reading watt meter on order that should be here next week so I can more accurately measure RF output and I will run my test using it. I also did an on air test where I used Preview 7 and Preview 12 using the same configuration, only adjusting the MIC gain to give equal 0 dB on peak readings and was told that the Preview 7 was much stronger and didn't have any distortion on the audio signal (subjective opinion, of course). With Preview 12, the signal was much weaker and the observer couldn't tell any discernable difference in the audio quality other than to say both sounded very good, but because the preview 12 version was less strong, he couldn't give a honest opinion to if it was less over driven or not. I understand how SSB works and I don't expect to see 80-100 watts output continuously, but the behavior I expect is to see some peaks above 50 watts and a higher value for average power. I also understand your explanation concerning the AGC limiting the RF output and not wanting to over drive the PA, but when I can get 100 watts (and more) out on CW and PSK distortion free, 20 watts on SSB voice seems to me a little bit aggressive. Maybe the AGC is working too well. My testing methodology is the best I can do right now with the tools I have and if there is some flaw in my logic, I'd like to know so I can make the appropriate changes. I am very pleased with the changes made to the RX in this preview stream, but a four fold decrease in TX output from preview 7 to 12 is obviously not what I was expecting. I just don't have the antenna system to start working QRP :-) Do you have any suggestions for parameter I can work within the software that might elevate the low TX power issue that wouldn't adversely affect the RX quality? I'm not criticizing or complaining, just concerned that one of the features of the radio I expect to behave at a certain level is not. I am open to any suggestions other than to just live with the low power output or use only preview 7. -Tim --- Tim Ellison ( [EMAIL PROTECTED] ) Integrated Technical Services ( http://www.itsco.com ) -Original Message- From: Robert McGwier [mailto:[EMAIL PROTECTED] Sent: Friday, January 20, 2006 11:58 PM To: Tim Ellison Cc: [EMAIL PROTECTED] Subject: Re: Steady drop in output power with successive Previews. All things where the peak used to exceed the target level by a lot, will be rolled back now that the agc is actually working correctly for the first time. The reason for the fast/slow track agc is so the average power will not be lowered significantly but the peaks will be rolled back. Bob Tim Ellison wrote: Bob, Thanks for the explanation. I am actually using both the FWD PWR meter and an external meter. I don't claim absolute accuracy and it is hard to get accuracy without a true peak reading watt meter. I have a fairly good idea what the power reading is close to, but I am mostly using it to judge changes in magnitude assuming that it is close in linearity. Would the AGC changes also be responsible for reducing the effect of the limiter as well? I'll trying playing with the CPDR tomorrow after work. -Tim --- Tim Ellison ( [EMAIL PROTECTED] ) Integrated Technical Services ( http://www.itsco.com ) -Original Message- From: Robert McGwier [mailto:[EMAIL PROTECTED] Sent: Friday, January 20, 2006 11:12 PM To: Tim Ellison Cc: [EMAIL PROTECTED] Subject: Re: Steady drop in output power with successive Previews. We are in fact throttling way back on the peaks with the fast channel in the agc algorithm. However, let me say that we have been letting the amplfier be seriously overdriven, in fact, into nonlinearity. The patterns we are seeing on the oscilloscope are nearly perfect Christmas tree patterns. Trying engaging the CPDR and also adjusting the TX

Hi Bill, Squelch works fine here. However, you have to enable SQUELCH by clicking on it. The enabled state is indicated when SQUELCH turns yellow.

[Flexradio] mute version 12
The problem with mute in version 12 is that it WILL activate yellow when the software is in STANDBY mode. When you switch the software to ON it will not go yellow on pushing the mute button. Bill Nagle http://home.ptd.net/~w3duq
Re: [Flexradio] mute version 12
Bill, It's an either/or situation. If you activate the option, the panel button will not work and the x2 pin WILL mute the receiver. If you don't select the option the panel button works but the x2 pin will not. The option appears first in Preview 9. --Larry W8ER - Original Message - From: Bill Nagle [EMAIL PROTECTED] To: FlexRadio@flex-radio.biz Sent: Sunday, January 22, 2006 6:12 PM Subject: [Flexradio] mute version 12 The problem with mute in version 12 is that it WILL activate yellow when the software is in STANDBY mode.

Re: [Flexradio] RFE BOARD QUESTION
Phil, I am going off of memory here, but I believe the XVEN signal goes high whenever the 12 or 13 of the following is true: 1. XVTR Enabled/Present is checked. 2. Positive logic is selected and you are in TX. 3. Negative logic is selected and you are in RX.
