Re: [Flexradio] Soft clicking when NR and ANF are on

[Flexradio] Bandwidth Control proposal by K2WS
I have designed a bandwidth control system for the SDR. I believe most operators will find this approach to bandwidth control, familiar because these methods have been used on Kenwood and Yaesu radios for years. It takes up little console real estate with its two sliders indicators and 1 pushbutton. It gives the user a choice of lowcut/highcut slope tuning or bandwidth/IF-shift tuning using two sliders . IMHO, the former is more useful for CW and the latter better for SSB AM. I have a description of the system and some hand drawn sketches of the lower right section of the SDR console - with examples of use in SSB and CW. click here http://www.tracey.org/wjt/sdr1k/k2ws-fltctl-ideas.pdf; Bill, KD5TFD was kind enough to host my efforts. We have talked about it and he may try to impliment these ideas. Please let me know what you think. Thanks! 73, Alan K2WS
RE: [Flexradio] Build 72 of vCOM driver and HRD
Phil, I loaded build 72 over the long weekend. It worked fine with MixW but I got a BSOD (BAD_POOL_HEADER) more than 50% of the time when I tried to start DXLab Commander (which was not responding when I didn't get a BSOD). Running Beta 1.3.5 on a Dell Dimension 8400 and XP Pro.

Ken, Based on your response, I checked out my USB devices. They are the SDR USB to parallel adapter, the Griffin PowerMate and a mouse. I subsequently removed first the PowerMate and then the mouse (!), while PowerSDR was running, but to no avail, so I'm still open to ideas.

Alan, I like your idea very much. I would like to try it out on psk and the other modes. I see a lot of application for this. 73, Dale AA5XE Alan Davis wrote: I have designed a bandwidth control system for the SDR.

Re: [Flexradio] Build 72 of vCOM driver and HRD
Hi Bob, Yes, I have been fighting the BAD_POOL_HEADER problem since I got back from vacation. It seems to be a timing problem because when I have windbg running I can not get it to crash (since it slows down the system). It passes verifier and prefast testing also. I have tried debugging it with the debug system running in VMWare and two separate machines with a real serial connection - no luck. Whenever the system is slowed down by debugging I cannot get it to crash. This, in itself, gives me some ideas on where to look for the problem and that is what I am working on now. I am hoping to have a fix in a day or so. If someone could email their memory.dmp file after a BAD_POOL_HEADER bugcheck it would help greatly in analyzing the problem. 73 de Phil N8VB If possible, could On 6/1/05, Bob Tracy [EMAIL PROTECTED] wrote: Phil, I loaded build 72 over the long weekend.

Re: [Flexradio] Soft clicking when NR and ANF are on
Joe: Do the following. Fix the console so that you have the soft clicking going on. The change the spectrum display mode from spectrum or panadapter, etc. to OFF. Tell me if the click goes away. It does here on the development system in my lab. Bob Joe - AB1DO wrote: Ken, Based on your response, I checked out my USB devices.

Re: [Flexradio] RFI Issues
Wally and all, Since receiving the SDR-1000 in July 2003 I am fighting the RFI, spurious, noise and common mode issues and no final and universal solution yet! So far I try to manage with isolating transformers in I/Q lines (input and output), ferrite beads in parallel cable as well as the USB to Parallel cable, strictly a single point grounding system (star configuration) and on top of all I have a 7.5 kVA UPS system for powering my office/lab/hamshack. IMHO, these problems are related to the fact that no theoretically clean star groundings can be created and ground loops eliminated, mainly due to the common practice of connecting together the Protective Earth (PE) and Signal Earth already inside the electric/electronic appliances, especially the PCs. PLEASE, NOTE! The problems are not alone with the SDR-1000 only. My Yaesu and Icom equipmet suffer these problems, too, as soon as I connect the PC to them. Whatever systems I have had, a careful routing of cables, experimentation with the grounding points, common mode and differential mode filtering, signal line balancing and shielding were needed. When it comes to the RFI, keep all radiating wires and cables as far away from the hamshack as practical. A lot of wonder antennas may have essential part of radiation coming from the feedline - Carolina Windom included. Sorry Wally, I have no ready made solution for you. Believe me, all these requires good understanding of the theory, but that is not enough. Finding the optimal wiring in our wireless hobby is art that beautifies the science. Who would make the optical fiber interface for our SDR-1000 so that we don't need to be artists and scientists at the same time? 73, Ahti OH2RZ - Original Message - From: Wallace Watson [EMAIL PROTECTED] To: FlexRadio@flex-radio.biz Sent: Tuesday, May 31, 2005 11:54 PM Subject: [Flexradio] RFI Issues Greetings All, I have had my SDR-1000 now for approximately 3 month and find the receiver very pleasurable to use. New additions are being made to the software for the radio adding to it's functionality. My computer is an HP/Compaq Celeron 2.4Ghz with 512Mb of RAM. I initially purchased a Creative Labs Audigy 2ZS card but I never installed it in the computer, instead when the M-Audio sound card was mentioned on TeamSpeak and posted in the forum I decided to purchase and install it instead. Prior to the Dayton Hamfest I ordered a Behringer UB802 mic preamplifier/mixer for SSB use vice installing a second sound card in the computer. I hooked up the Behringer mixer the day I returned home from the Dayton Hamfest. I also had switched to using the USB cable for use with the SDR-1000 prior to this. I have since begun making contacts on 80 and 40 meter bands on SSB and experimenting with CW using the automatic memory and keyboard modes with the SDR-1000 with the 100 watt amplifier. I have been experiencing RFI problems when I switched to using 30/20/15/10 meters with my primary antenna system, a Radio Works Carolina Windom. The antenna vertical radiator terminates immediately overhead my family room which serves as my ham shack. The RFI problem manifests itself as follows: When using the USB cable between computer and radio, when I transmit on 30 meters or above the radio begins by transmitting and then I get a High SWR indication on the display and the radio reverts to the Standby mode. I am unable to switch the radio back on via the software Standby/ON button, I must instead disconnect/reconnect the USB cable from the computer or reboot the computer. I have been semi-successful at reducing/partially eliminating this problem by reducing output power to approximately 35 watts. In an attempt to eliminate this problem I switched back to using the original parallel cable between the computer and radio, with this cable in place on 30 meters and above I am able to go into transmit at the 50 to 100watt level and the radio will transmit in SSB or CW but will shut down the 100watt amplifier while in operation, when I come out of transmit mode to receive the receiver is no longer receiving signals, I must switch off the radio and back on using the Standby/ON button on the SDRConsole. If I reduce power to an approximate 35 watt level, the radio functions normally. I have a second antenna, a tape 40 meter dipole, this antenna is usable on 40 and 15 meters only. With this antenna I have completely normal operation on 40 meters and with the Carolina Windom, I have completely normal operation on 80 and 40 meters. I have 3 other radios at my location, a Kenwood TS-440S, a Kenwood TS-450S and an old Yaseau FT-101EX and have experienced no problems on the air utilizing any of these radios. I believe my next step is to order and install the Radio Works ground isolators in the hopes that this will eliminate my apparent RFI/ground loop problem which are interfering with my operation of the SDR-1000 radio. I have no option to move the Carolina Windom antenna. I do
