[Flexradio] Using MMTTY and APRS with two Sound Cards(HELP)
I am using the FlexRadio 1K with the Delta M44 sound card and operate MMTTY sucessfully via The VAC software. However, I am having probems in connecting my external VHF radioAPRS to the built in Realtec soundcard. I have tried the control panel sounds and audio devices but can only get either the M44 or realtec soundcards to work independently. The probem is to get the MMTTY to work via the VAC from the Flex 1K and to get the APRS audio from my VHF receiver to connect via the mic or line jack on the PC to the realtec or even to the Delta M44. Can anyone please help? 73 de Howard 5B4AHX ___ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kb.flex-radio.com/ Homepage: http://www.flex-radio.com/
[Flexradio] X2 control problem - SDR-1K Ext Linear Amp.
I have just developed a problem when switching my linear amp using X2 Pin 7. My linear amp is an HLA 300. The system has worked well for past 6 months but now when going to MOX with X2TR on, it does not switch the amp on. I have read the notes about coupling the switching control and all voltage /currents are within allowable limits. The darlington transistors rating of 50v/500mA are not exceeded so I have not used an external relay. My linear amp control has just +3.8v on control line and requires a ground for operation. Only a few milliamps are flowing when grounding voltage on base of linear amp switching transistor. When I measure the X2 control line pin 7 when connected I get 3.8v on rx and 0.6V on tx when switched (MOX). I assume that the ULN2003AD is faulty as the amp needs zero volts to switch on. Manually grounding the linear amp contol line works normally. I have also checked some other X2 pins and when software enabled I measure 0v when unticked and 0.6v when ticked on receive using DVM. The Flex 1k unit is still under warranty but I can execute repair if you please advise the next procedure and can supply spare.

[Flexradio] Audio Clicking on PowerSDR v1.10.2 on Transmit
I have been testing my Hampal Digital SSTV software with SDR-1000. When transmitting a carrier on TUNE (10Watts), I get an audio click which is on the carrier and repeats erraticly. I am monitoring using a separate receiver(s). Sometimes it repeats the audio click within a few seconds or maybe up to about 40 seconds later. This must be a difficult problem to find. I have checked all my hardware connections and it only happens with the above software version. My PowerSDR Beta v1.9.1 and earlier versions do not exhibit this fault. It would be unnoticeable on voice but can corrupt up a digital transmission. The fault occurs when on any mode, i.e, USB,LSB,CWU,CWL,DIGU,DIGL.etc, and whether Hampal is closed or not. I have checked my settings on each PowerSDR version and using the following settings:- Audio buffer size 1024 DSP buffer size 2048 DMA buffer DeltaM44 size 256 Sample rate96Khz I have tried altering the above. Can anyone please help? Regards Howard 5B4AHX. -- next part -- An HTML attachment was scrubbed...

[Flexradio] Noise on Changing Frequency above 20M Band
I have noticed a high noise level generated when changing frequency only on bands above the 20M band, especially when using the sliding mouse. The noise generated is as high as 15dB above the noise floor. This is the same on all versions of software that I have used so far. Has anyone else had this problem or do I have a PC installation defect? 73 de Howard 5B4AHX. -- next part -- An HTML attachment was scrubbed...

Re: [Flexradio] Problem calibrating frequency.
Hi Dan The problem in my case is the software for reasons that the Beta 1.9 is not compatible with the Ver 1.8 so far as calibration is concerned. Maybe the mod you did is tied up with the software not being compatible. 73 de Howard 5B4AHX - Original Message - From: Dan Scott [EMAIL PROTECTED] To: Van de Velde Eddy [EMAIL PROTECTED] Cc: [EMAIL PROTECTED]; [EMAIL PROTECTED] Sent: Sunday, August 12, 2007 5:17 AM Subject: Re: Problem calibrating frequency. I sent a message to Ed at Flex and he got back to me immediately. For me, I determined that problem was NOT related to the software which ended up being correct. The issue I had with instability related to the crystal heater and he had me disconnect one of the wires inside the SDR1000. My system is now stable. It took a couple emails but I'm fairly well satisfied. He also has me marked down as having this problem and will send new parts if the problem happens again. So, you might want to contact flex directly. 73, Dan - kb0ppm Van de Velde Eddy wrote: Hello, Has anyone of you got an answer for this problem ? Dozens and dozens of mails on the reflector but no one seems to care at Flex about our problem. I can understand that the 5000 is their first priority. But they could at least say they are going to check it, couldn't they ? Are we the only four with this problem ? I would not think so. There must be more people that have tried Beta 1.9.1. and detected the same problem. Or do the other just don't care ? I am beginning to think that The new software is now specific for the 5000 and that the 1000 will run on it as well but with some set backs. If anyone of you has more news, I would like to hear from you. 73 Eddy ON5UQ ___ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://www.mail-archive.com/flexradio%40flex-radio.biz/ FlexRadio Knowledge Base: http://kb.flex-radio.com/ FlexRadio Homepage: http://www.flex-radio.com/
[Flexradio] Freqency Calib Inop
I have just tried the new Power SDR Beta v1.9.1 and cannot calibrate the frequency as I do with v1.8. When I check 'calibrate' I get a message 'Peak is outside valid range'. My receiver is out of calibration by 160Hz against my reference. Can anyone help? Regards Howard 5B4AHX -- next part -- An HTML attachment was scrubbed...
