  1. I enjoyed the interviews with Mick and Bob Wald. I was interested in Mick's because I am one of CSI's biggest fans. I don't believe that I have missed a single episode. Great work, Mick. I read the interview with Bob Wald because he is an old friend that I met through my former employer, and haven't seen in a while. Thanks for the good work John. David W White D.W.

  2. Count me in. I'll will be there. David W White
  3. Well ahead of schedule, D.W. Sound Service is very please to announce that our new website is up and running. In the coming weeks we will be adding to it. Our blog will be moved to the website very shortly, and we will have a new "Tech Tip" section. It is our hope that not only will we have tips and technical articles written by us but, have tips submitted by those of you working out in the field. We would say big "Thank You" to one of your fellow sound mixers, Richard Ragon at good4sound.com. Without Richards help, this new website would not have been possible. David W White D.W.

  4. If these devices continue to fail, it will push back the date for them to be implemented. That will give the wireless mfg's and end-users more time to figure out what their next step will be. The day will come when someone will figure out how to get it to work.
  5. In the next two weeks our website will be completely new. With more information, links and news about the industry. We will also have several exciting announcements at that same time concerning new services we will be providing. In the mean time we have a new blog. It will have comments and information about happenings in the industry. From bandwidth proposals to new product roll-outs. Feel free to visit and comment. The URL for our new blog is: dwsoundservice.blogspot.com David W White D.W. Sound Service www.dwsoundservice.com
  6. I would like to see some mixer set one of these up on location and see what kind of comments they get. Especially if they were to make it look as though it was actually doing something. David W White D.W. Sound Service www.dwsoundservice.com
  7. The reason that the Amateur Radio Service is alloted it own bands of frequencies is that Amateur Radio is used as a public service during disasters and emergencies. For example, in New Orleans, after Katrina blasted that city, amateur radio was the only form of communications for many months. These radio operators were volunteers who came from around the country to help. They are also used as vital communications links between the many different agencies that will be called up for any type of emergency or disaster such as fires, earthquakes, hurricanes, etc.... They practice and drill with these emergency response agencies throughout the year. And Amateur Radio plays a big role in any local, state, or federal government's emergency response plans. It's not just a hobby. David W White - KO6FN D.W. Sound Service www.dwsoundservice.com
  8. Amateur Satellite is an experimental service that allows Amateur Radio Operators to ability to make contacts using orbiting satellites. The satellites belong to an organization of Amateur Radio Operators. They pay for them to be built and shot into space. They are used almost as orbiting repeaters. The challenge is trying to track the satellites so that you will know when they are positioned correctly. David W White - KO6FN D.W. Sound Service www.dwsoundservice.com
  9. Not to sure if this has been posted here yet, but, the invasion of the broadcast band may not be as far off as we think. Take a look at this link and see what you think. Google thinks they can make this happen as soon as the end of 2009. I would hope that the broadcasters and wireless mfg's have a little weight to throw around. http://news.yahoo.com/s/nm/20080324/tc_nm/google_fcc_dc;_ylt=AnlmrZfsahOOy1VnU9BtwdCs0NUE
  10. I agree. this looks good. I hope you keep it.
  11. To simplify Scott's post, the tracking front end on the 211 and 411 works something like this: the bandpass filter on the front end is only 6MHz wide. It tracks up and down the block, centered on the frequency that is selected. The rejection for signals outside that band is quite good. It helps eliminate interference and make the 1st I.F.'s job much easier. The down side of this tracking front end is that it chews up lots of power. It was first introduced in the UCR200 and 205 models. That is the main reason why batteries couldn't be used in these. The redesign of the circuit from the UCR210 and later brought level of power consumed down so that batteries were able to be used. the 201 and 401 do not use the tracking front end. The front end of these units are open across the entire 25MHz of the block they are in. Any signal that is present will be passed through to the 1st I.F. The bandwidth of the 1st I.F is very tight and will almost always be able to filter out unwanted signals that would be a cause of interference. The tracking front end is another layer of protection against intermod and interference getting introduced into the signal path. David W White D.W. Sound Service www.dwsoundservice.com
  12. Robert, Unless you have any voltage coming out of the antenna input of your TV tuner, the Venue really wont care if it is connected or not. Your reception will be another story altogether. There is an RF filter between the BNC input and the BNC output connectors. The bandwidth of this filter is pretty tight and drops off rapidly at the top and bottom end of the blocks that the Venue is tuned to (in your case Bk's 21/22). The signal that you will see at the output BNC has already been through this front end and in theory the bandwidth should be only 50MHz wide. There is also a buffer amp in this circuit so the signal should be approx the same as the input, -0db to 2db. If the frequency that the TV tuner is looking for is looking for is in that 50MHz bandwidth, you should be able to see something. The quality of that signal would be very questionable. The first thing would be that you will most likely be using 50 ohm coaxial cable. Video signals are not real fond of that. Video likes to see 75 ohms. The next thing is that the circuit between the input and output BNC connectors was most likely not designed for video signals and there may be some degrading of the signal at the output. And lastly, if the frequency is not coordinated properly with the wireless frequencies that are being used, you may be looking at having some type of interference troubles, shortened ranges, noise, dropouts, etc.......... Have said all of that, I have seen some sound mixers use their wireless equipment in ways that, because of circuit design and theory, should not be working. But, it does. David W White D.W.

  13. The Loctite idea is most likely the best. The problem with the Teflon tape is that it insulates the threads of the nut on the antenna, which is normally grounded through the threads on the SMA connector on the transmitter. Though the chances are small, it is still possible for noise to be created through the antenna when the nut is not correctly grounded. If you are going to use the Loctite, make sure that you use the correct adhesive formula. The 222 and 242 will work the best as they are the weakest of all the Loctite. Any stronger any you might cause damage to the antenna or the connector when trying to remove the antenna. David W White D.W. Sound Service www.dwsoundservice.com
  14. I don't watch reality shows but, I sure do have all the respect in the world for the crews that do some of these shows. They have be a real bear to work on. David W White D.W. Sound Service www.dwsoundservice.com
  15. We are in the process of obtaining the "Authorized" status from many of the mfg's. We are on track to making an announcement with respect to several of them by NAB in April. This forum will be one of the first to know when that happens. We will also updating our website with new and exciting information over the next several weeks to include service options that are not offered by other service centers in the Los Angeles area.

  16. The speech programs aren't the only ones. If any of you have XM radio, listen to the traffic reports for your local city. At least for L.A., they butcher our street names. David W White D.W. Sound Service www.dwsoundservice.com
  17. Ronnie and I worked together for several years. So, I have always taken an interest in his work. He continues to amaze. The question I have is, How difficult is it to work with all the egos involved with that show?? Welcome to the forum. David W White D.W. Sound Service
  18. We have dealt with the RF from cameras for many years. Most wireless systems are shielded well enough that it is not a problem. Comtek receivers don't have adequate shielding and are susceptible to interference troubles. If you are going to use a PR216, make sure that is is one of the Option 7 models with the BNC antenna. You will eliminate a lot of potential problems. David W White D.W. Sound Service
  19. For those that would be interested, we can make arrangements for Pick-up and Delivery service. Let us know and work out the details. We have also worked out a deal with a company in the Burbank area so that you can pick up and deliver your equipment locally. Thanks, David W White D.W. Sound Service www.dwsoundservice.com
  20. D.W. Sound Service is located in the Santa Clarita area. For those unfamiliar, it is about 30 miles due north of Downtown L.A. Thanks, David W White D.W. Sound Service
  21. I never dealt with Andy and or Janet as an end user, I had many dealings with them from the service and repair end. They were always helpful and took the time to help me get through several trying repairs. I want to thank them for the help and time, and wish them the best. You both will be missed. David W White D.W. Sound Service
  22. My name is David White. I was a technician at one of the biggest audio dealers in the business for 15 years. Over that time I have worked on equipment that belongs to most, if not all, of the location mixers in the industry. I have opened my own company, D.W. Sound Service. Although we specialize in service and repair of wireless and communications equipment, we also service Mixing Panels, Slates, Power Supplies, Amps, and most of the equipment that is a part of your sound packages. We will be expanding in the very near future to include Cable and Microphone repair. If there is any way that we might be of "service" to you, please give us a call at (661) 297-4090.
