  1. Lectro SRc field reports?

    Only the engineers, who will be furiously concentrating on getting the tape and labels stuck on, perfectly aligned. LEF
  2. Lectro SRc field reports?

    The plate will be provided free of charge for a week or so, if you don't want to purchase one. Update the unit, send the plate back and we will loan it to the next customer. Easy on you, easy on us. Lectro will request a credit card number to make sure they get the plate back so they can use it again. Best, LEF
  3. Lectro SRc field reports?

    Looks like Gordon and I crossed answers. LEF
  4. Lectro SRc field reports?

    A1 only. The fault is that block 18, if it existed, would start at 460.8 MHz (25.6 MHz times 18). However, the bottom of the legal spectrum is 470 MHz, known as block 470. Notice that there is 9.2 MHz difference between the bottom of the non existent block 18 and the 470 MHz bottom of block 470. This where the 9.2 MHz error came up. This problem of a non-mathematical block doesn't exist in B1, etc. So, A1 only has this problem. As far as your other problems with B2, I can only suggest that speaking directly with Lectro about a weird problem is roughly 103 times better than going through a dealer. Too much gets lost in translation. Like the venerable kids' game of "gossip". The seven hour offset is a bit of a problem, but setting up a time by email should work. So will an info dump by email. If necessary, service can and will get you to an engineer. (I despise 180 degree finger pointing). Best Regards, Larry Fisher

    Hi Brian, Thanks for the real world tests. I did a final test as promised on a brand new FujiFilm NP-50 from B&H and it tested out as 1.050 Ah (1050 mAh) which is within a few percent of the Lectro LB-50's and the previous year old (?) Fuji NP-50's directly from FujiFilm. One can assume all these batteries are OEM'd from Panasonic. I can say that you will get the best operating time possible from the LB-50 from Lectro or the Fuji NP-50 from B&H. Different battery brands bought from fly by night sources, will probably not meet their specs. Be very, very wary of any NP-50 style battery that claims more than 1000 mAh or has a much lower price. By lower price, I mean anything under $29-30. Best Regards, Larry Fisher
  6. Lectro SRc field reports?

    The Scan function is where the bug is. However, SmartTune uses the results of the bad scan. Therefore, both can be 9 MHz off. Until your units are reprogrammed, use an external scan or check the RF level of single frequencies on the display. Best, LEF
  7. Farewell innovation?

    In a sense it hasn't even started yet. The lawyers are still filing briefs as to where the case will be heard; New York or New Mexico. It will probably be months before a decision is made by the court as to location. What a waste. LEF
  8. Lectro SRc field reports?

    Correct. If you use the SRc scanning function to select a frequency, it can incorrectly put you in an RF active region, 9.2 MHz away from the intended quiet frequency. If you manually select a frequency, the frequency and RF level displays are all valid. You can single step through frequencies or select frequencies from an external scanner and get valid frequency and RF level results. This problem may have been in existence for many months but the Lectro crew has only understood the cause for less than a week. It takes a few days to rewrite the firmware and proof it. Then a day to bring the service people up to speed. Pull out a weekend and one can see the response has been pretty quick and open. Check out Allen K's Facebook link above to get the latest info and the planned and logical fix. Best Regards, Larry Fisher
  9. Sound Devices acquires Audio, wow!

    We make one little tiny recorder....
  10. In a PM, Gordon said we would make loaner programming endplates available for updating in the field. That will save the shipping time of a factory reset. Best, Larry F
  11. Here's a post from Gordon on the Lectro facebook page. Might explain a lot of weird things with the SRc. Since the scanned frequencies can be off by 9.2 MHz, a "good" frequency could be off by 9.2 MHz. Setting the receiver to the "good" frequencies could actually (probably) put you in the middle of major interference. The post: <Doug Pearson for the win! Doug recently posted pictures showing a discrepancy in the scans between a block 19 SRB and an SRC -A1. After several days of trying to duplicate the problem we finally found it (and are kicking ourselves for not catching this sooner). This answers the problems you ALL have been having with getting interference on "good frequencies" as shown on the scan of the SRC-A1. There is a bug in the firmware that runs the scan. It was improperly indexing the channel selection in the scan and the hexadecimal value for the frequency was off by 9.2MHz! That's why Dougs pictures showed clear at EE on his SRB and messy on his SRC. The receiver was working fine, the scan firmware was not. This also skews the values the SmartScan by 9.2MHz. (not so smart, huh!) So, while we will continue with beta testing the SRC new rev boards for their improvements - there ARE improvements there - we have FINALLY found the smoking gun for the majority of weirdnesses the SRC has shown. This will require a firmware update for ALL SRC-A1's . We are investigating the B1 and C1 as well to make sure there isn't a similar offset problem.>

    Hi Brian again, I note a earlier post in which you got 3.5 hours out of the Lectro's and "nearly 3 hours" out of the Watson. That corresponds perfectly with my 2.8 hours divided by 3.5 hours equals 0.800 Ah, the claimed Watson numbers. So you've already tested the batteries exactly as I recommended. Best Regards, Larry Fisher Hi Martin, The SSM shut off voltage is 3.0 Volts, according to DT at Lectro. That is a very common shut off voltage for electronic gear with moderate current draw. It gets near maximum capacity out of the battery while leaving some residual behind to protect the cell. Again, it is recommended to change cells at 4 to 5 hours when it is reasonable. That would give you 300 cycles, whereas a full discharge of 6.5 hours might give you only 150 cycles. On the other hand, 150 cycles is less than 30 cents a cycle even for our "overpriced" batteries. Best Regards, Larry Fisher

    Brian posted : "I have bought several, and found their performance to be quite similar to the Lectros. :-) for 1/10 the the price. :-) Since 6 of these cost $30 it was a cheap experiment that paid off so far. Since we're talking about having some empirical evidence on the performance of NP-50 batteries, why not test them all? Like scientific and stuff. :-) I don't have the same test equipment as larry :-)" Hi Brian, I'd buy one for curiosity and test it but, good, bad or indifferent, I'm not going to recommend a Li-Ion that doesn't have safety markings (CE and/or UL/UR). I don't even want to imply a battery is safe by publishing a test. A over heated battery on talent is not something I want to think about. Here's how you can reasonably test the Watson batteries yourself. Run a transmitter with a new or moderately used Lectro NP-50 and make the assumption the Lectro is 1 Ah. Then try the Watson battery and see how long it runs. If it runs 60% of the time, it's surely a 600 mAh battery. For instance, if your brand transmitter runs 3.5 hours on a newish Lectro and runs 2.1 hours on the Watson, you have the aforesaid 600 mAh battery (2.1/3.5=0.60). I note the Watson claims 800 mAh so you should get 2.8 hours (2.8/3.5=0.80). Best Regards, Larry Fisher

    Hi Brian, Every low cost NP-50 I've ever tested was a piece of junk. After so much heartache and disappointment, I've given up on looking for batteries in all the wrong places. Particularly those with no CE or UL markings. Best Regards, Larry Fisher

    Hi Derek, Pretty good. Probably the easiest of all the battery types. The Li-Ion's have got a very nice straight line of voltage versus discharge so it makes it easy to meter, unlike Ni-Mh which is essentially impossible. Best Regards, Larry Fisher
