radarblaster Posted October 16, 2013 Report Share Posted October 16, 2013 Headed to Chicago, this topic has probably been covered but what are usable blocks in the city. Quote Link to comment Share on other sites More sharing options...
Matt Mayer Posted October 17, 2013 Report Share Posted October 17, 2013 24 used to be great and is now a mess down town. Good chunk of 23 is useable, I was able to squeeze 8 channels in block 21 a few years back. My hops are in 26 and I rarely have a problem finding clean frequencies.

studiomprd Posted October 17, 2013 Report Share Posted October 17, 2013 probably... all the legal blocks are useable, and interference will vary from time to time, and from place to place. Quote Link to comment Share on other sites More sharing options...
gpiegari Posted October 17, 2013 Report Share Posted October 17, 2013 Avoid block 22. Quote Link to comment Share on other sites More sharing options...
radarblaster Posted October 17, 2013 Author Report Share Posted October 17, 2013 Thank you fellas, obviously I'll scan each location first and since I will be working out of a bag with 8 receivers I shouldn't be too far from actors.

Rob Lewis Posted October 18, 2013 Report Share Posted October 18, 2013 Just did a show a couple months back. 19 & 21 for cast were pretty good. 25 for IFB and 24 for camera hop all in the downtown area. Call Lectrosonics and get a coordination done, its free and will help immensely . Quote Link to comment Share on other sites More sharing options...
Glyn Posted August 3, 2015 Report Share Posted August 3, 2015 Reigniting an old thread. I am going to be in Chicago mid september recording with a couple of wireless lavs. I will be at the Chicago Marriott Downtown Magnificent Mile. What are the available frequencies? Have they changed from what has been mentioned above. Thanks in advance. Quote Link to comment Share on other sites More sharing options...
Matt Mayer Posted August 3, 2015 Report Share Posted August 3, 2015 If anything, things have gotten worse. If you are inside, you can probably get away with any block. If you are outside, the RF is really strong since you are blocks from the major TV transmitter site in the city (John Hancock building and Sears Tower). Not sure if this link will work, if not, just go to the site and use the "Check your address for free TV" link http://www.tvfool.com/?option=com_wrapper&Itemid=29&q=id%3d8e033b97601d8d Based on this chart, looks like, without doing the math and looking up block frequency ranges, you can find clear air in blocks 19, 20, 23 and 25.

L7NirvanaLove Posted October 13, 2017 Report Share Posted October 13, 2017 Hello guys, I'm looking to get another wireless kit for my bag. Currently using BLK 19 and for the most part the lower half of BLK 19 works well for me across city. Is there any other BLKs that would be recommended for use across the city that generally has some free space? I know RF interference varies from location to location but if anyone has experience with different BLKs that work well. I would greatly appreciate the advice. I have experimented with BLK 21 with little success. Quote Link to comment Share on other sites More sharing options...
Derek H Posted October 13, 2017 Report Share Posted October 13, 2017 Just avoid 22 25 is also pretty much toast except for a small chunk on the top and bottom. Enough for 2-3 transmitters at least Quote Link to comment Share on other sites More sharing options...
PaulE Posted March 12, 2018 Report Share Posted March 12, 2018 (Despite knowing the answer) I'm gonna drag this up and ask if there has been any change in block 25, good or bad? Quote Link to comment Share on other sites More sharing options...
