  1. Prototype BEC bracket for F55 Documentary Dock

    Ah, yeah I can see why that would be confusing... The side plate bracket is part of the battery adapter (V-Lock to Anton Bauer I think) and won't be used on the actual camera configuration for the job I'm doing (I just went in to VER and grabbed a camera to test the prototype bracket). The F55 Dock doesn't have the two screw holes on the very back of the camera (behind the slot-in receiver plate) to secure the adapter plate like you would on a F800 or similar, so even if we did use that adapter it wouldn't be secure enough to take the weight of the RX200. I could probably have bodged something but the job I'm prepping for is a three month shoot all over the world so it's worth a bit of expense to make a really solid rig! Totally agree on the universal mount idea. I was vaguely talking to Mike about making a bracket that consists of a horizontal piece with two screws in a slot (like a tripod plate) to accommodate different spacings of holes, which would would be joined to a sliding vertical piece which could be moved closer or further from the camera, which would have the standard 4 BEC mounting holes. Kinda hard to describe, but could be a simple solution to ever changing camera rigs...?
  2. The awesome Mike Babcock at BEC turned my crappy drawing into an excellent bracket for attaching a receiver (RX200 in my case, but whatever fits into a BEC box) onto the Sony F55 with documentary dock. Just tested out the prototype today and it works really well - allows all the BNC's for SDI outputs to connect and pass under the box. Obviously the finished product will be "BEC black" but thought I'd put this up here in case anyone's looking for something like this...
  3. Waterproof case for 633

    Aquapac make a really good waterproof duffel bag. Ive tried many versions of roll top bags for waterproofing kit (for me, I usually have to have it attached to my harness to wade or jump in water in caves and such) and this seems to be the best. It's not transparent, although I did find a transparent one that is absolutely giant and too big for a 633 really. It's got a load of mounting points plus (and I think this is unique) a purge valve. Use an IFB for monitoring when it's closed, obviously... https://aquapac.net/store/shop/waterproof-bags-duffels/upano-waterproof-duffel/ i think it's the smallest one that fits the 633.
  4. IFB, Hops and Talent RX question...

    Wow - now THAT is an answer! Thank you so much! That explains why in my test, which was really a worst case scenario with the transmitters and receivers much closer than they would be out in the wild, I didn't see any difference in reception when the transmitters were switched on or off. As I mentioned, I'm using this particular setup in remote locations so I'm not likely to hit any unknown frequencies, and I can coordinate everything. I can see how one could end up getting effectively "boxed in" if you were to do this in a frequency rich environment, though... J.
  5. IFB, Hops and Talent RX question...

    I just got round to doing a test... I don't have the exact system I'd be using, but I set up two TRX-LA3.5 on block 22 @100mw, 3x wisycom tx on block 19 @50mw, and 2x SMQV on block 24 @100mw... The trx's as talent mics, received by a QRX200 with whip antennas in the bag, and all the other transmitters right next to the QRX in the bag too, antennas almost touching (I was trying to go for worst case scenario)... Freqs coordinated on Freqfinder. Walked the TRX's to the edge of their range with all the transmitters in the bag switched off, then turned them all on one by one. Absolutely no reduction in range at all. Obviously I'm mixing digital with analog here, so it's possible that if everything was analog (or hybrid) it might be a different story, but it looks like all is well in this case.
  6. IFB, Hops and Talent RX question...

    Totally, and I do all the usual scanning and freq finder stuff - I'm wondering specifically if having my talent receiver block in between the IFB and hop blocks, frequency wise, is likely to cause more issues than having the transmitters grouped into one block at one end of the spectrum and the receivers grouped into one block at the other end of the frequency spectrum. I'll still have at least one clear block in between the blocks I'm using... That's always been my workflow too, but I wonder if that's only true for adjacent blocks? I'll run some tests and see what happens...
  7. On bag based jobs where I have a couple of talent receivers (Sometimes Lectro, sometimes Zax) as well as hop and IFB transmitters (all SMQV's) I usually keep the talent wireless to lower blocks (19 or 20) and the hop and IFB transmitters in higher blocks (24 and 25). So my question is: If I were to have the camera hop TX on block 19, the talent receivers on block 22, and the IFB's on 24, am I theoretically likely to hit more intermod problems by effectively "sandwiching" my receiver blocks in between two transmitting blocks? There will still be a block of separation between transmitting and receiving blocks, but my gut says that spreading the frequencies out across the spectrum can't be the best idea... One thing to note - the job is an adventure type show, so the spectrum is generally pretty open, so I'm not dealing with too much other RF. Obviously I'll do some tests, but in the meantime, any thoughts? J.
  8. Bluetooth sender cheap on amazon

    I got one of these: https://www.amazon.com/gp/product/B01K8ANDCI/ Really just to use as a means of sending audio to a car radio that only has bluetooth when using as a follow car (seems that modern cars don't have aux inputs any more). Works great so far - not sure I'd want to rely on it as IFB though as even the smaller delay would be disconcerting if producers were in the same room as talent, I'd think...
  9. Tascam DR-10c losing date and time...

    Yeah, batt is 100% good, and the unit is basically new... I'll give Tascam UK a call tomorrow. Tascam USA aren't able to help as it's not sold in the USA...
  10. Tascam DR-10c losing date and time...

    Has to be, but I don't know if it's user serviceable? Loathe to just start taking it to bits...
  11. One of my DR-10C's has just started acting up, where after it's been off for more than a couple of minutes, "DATE TIME NG" appears on the display at powerup, then the unit goes straight to the date and time setting page with everything zereod out (see attached pics). I'm assuming that this is because the internal date battery is dead? the AA batteries are all good, and it has latest firmware. It's been sat on the shelf for probably near to a year, so it wouldn't surprise me if that's the case, but anyone had this happen? Anyone ever replaced the internal battery? I'm in the US (brought these from the UK) so I'd rather avoid sending them in for service if at all possible..
  12. Custom Necklace Mics

    Brilliant!
  13. That is interesting... Wish I'd been able to compare the old and new systems, then...
  14. I absolutely agree - I've even got much better range with homemade dipoles on my harness. Unfortunately for the particular show I'm prepping for, that won't work as it involves a lot of climbing, rapeling, cave swimming, etc, so the setup needs to be super compact and able to be handed off and literally tied to a bit of rope and dragged up a cliff face and suchlike. Anything extra attached to a bag or a harness is another thing to get caught/snagged/broken. Joy! Anyway, my point was that the difference between the new ZHD modulation and the "old" XR modulation seems negligible, when I was under the impression that it would be markedly better. It seems that it's horses for courses, and that in certain RF rich circumstances the ZHD mod will be a godsend, though. Not that this can't work in my situation - in fact I was on a big reality/survival show last year that was all TRX2.5 and QRX200 and it worked great, but we were aware that we were sacrificing range for the advantage of having a one-pack solution which was really necessary with upwards of 14 talent in the jungle for a few weeks! Upcoming show is only two talent (host and celeb) in jungle survival environments, so I'm probably going to stick with WM transmitters and ZFR recorders and have the best of both worlds... Ahhhh I wasn't getting what you're implying, Rado. So maybe ALL the modulations on the new firmware are better? That is interesting.
  15. Interesting. So you're saying that the XR modulation mode on the older firmware is different from the XR modulation on the new firmware?
