KenLac Posted December 6, 2019 Report Share Posted December 6, 2019 I'm thinking of picking up a used Lectro SRa receiver to pair up with my older 400 series transmitters. Anything to watch out for? (Such as missing features compared to later models, known bugs, etc.) Quote Link to comment Share on other sites More sharing options...
PMC Posted December 7, 2019 Report Share Posted December 7, 2019 I have two used SRb receivers in my 664 bag. I picked up the second last month after asking the same question. The dealer was offing SRa and SRb receivers for sale. I was told by an engineer at Lectro that the SR and SRa versions are susceptible to receiving RF splatter from other nearby transmitters. This is due to the circuit board design something like only three layers of traces sandwiched between the multi-layered PCB. He said compromises were made from the 400 series receivers in order to fit the new form factor of a slot receiver. The SRb has more layers and better shielding. Since i use G3 hop transmitters and a Comtek transmitter in the same bag, I spent the little extra for the SRb. Check the firmware version of whatever model you purchase. There are some bugs that the latest firmware resolves like reading transmitter battery levels. Quote Link to comment Share on other sites More sharing options...

Wonder if wrapping the side of the bag the SR receivers are in with foil, and putting the IFB TX at the opposite side of the bag, would help?

Freeheel Posted December 7, 2019 Report Share Posted December 7, 2019 Is this a specific SRA or are you asking generally? Many SRAs were upgraded to SRBs because Lectro offered a very generous upgrade path. The ones that were done in the States should have been laser etched with upgrade markings. For those done in other markets, you'll have to rely on the seller's documentation. Cheers, Brent Calkin Quote Link to comment Share on other sites More sharing options...
