receivers with new 1258MHz option

[MatCat]

My Bluebeams do just fine on 1258MHz. I worked on the project with RMRc well before the channel was released and adjusted the dimensions accordingly so it works great for either frequency.

Awesome, but what is the lowest/highest frequency one could safely use (I would say less then an 2.5:1 SWR)? I am starting to fly with other FPVers plus I noticed way less interference and issues when on a different channel then 1.280 during ground tests, but I don't want to use a channel far off enough to give a high SWR, eventually high SWR will kill the TX, at least if it works just like things used to back in my CB days :P.

my 1258 receiver is garbage, i asked for a refund. i pmed you about it already ibcrazy

I was thinking of ordering one of the 1258 receivers, what's your's doing?

I've got the digital saw upgrade one and am blown away at how nice it is.

It all depends on how much heat you are able to dissipate. If you leave the VTX in the big case, then an SWR of 8:1 should be no problem. Outside of the case, I recommend no more than 4:1, though.

mine got static after 500 meters.... i think it's faulty. even my hobbyking receiver works 10x better

thx.

I've done 4.7km with the RMRC digital RX sofar... Here is a video from yesterday, I am curious if anyone can help me figure out the little bit of interference I am getting... note my DVR pukes on static so it's not a continuous flight video (I would manually restart the recording when it cut off :P)

Make sure the SMA connector is seated all the way down on the threads, I had the same problem and had to tighten it with pliers to get it to seat all the way.

^^ Good point, any connectors for RF should be tight, hand tight just isn't good enough, I always use a pair of pliers to tighten up SMA/RP-SMA/F/Whatever else connector.
