I've been running my EzUHF for a short while now on my multirotors.
I'm using a regular diamond Tx antenna and a couple of sander style 433mHz DIY Rx antennas - not done anything to 'tune' for 459mHz.
I've just done a quick test flight - going straight up, to about 40m.
I got a flash saying ALARM briefly, but otherwise all seemed ok.
HOWEVER, i don't understand what the RSSI values on the EzOSD mean could anyone help
I'm getting mid 20's to low 50's with 0 bad and 100 on the right.
Just wondering if that sounds ok?
You can find an explanation and examples here:

Use link quality, it's far more intuitive (and indeed useful IMO) than using RSSI.
No need to worry about tuning the tx antenna in all honesty, but do just make sure you have the right size antennas on the rx end.
Its daft the way its laid out because the far left value id RSSI 1, the next value, although being right next to bad, is not bad, it is in fact RSSI 2. Bad packets is to the right of Bad right next to the antenna symbol. Then link quality is the far right value.
You want your RSSI 1 and 2 to be as close to 60 as possible, anywhere in the 50`s is great, 40`s OK.
Bad packet count as low as possible
Link quality the closer to 100 the better

I see that often, looks like this: private link ezuhf issue (http://www.youtube.com/watch?v=T0sF2o12P8M#)
Is yours doing that also? Where about are you flying?
And the RSSI values on the left, lower is better I believe? So on the ground you have a RSSI of like 5.
No the higher the RSSI the better, not lower

Pretty sure its different on EZUHF, The lower the better and the highest value is 255 I believe though that's obviously the lowest really.
Oh yes, I think your right, its a digital dbm value
yup. just had a questions answered on fpvlabs. EZOSD RSSI... the lower the better.
Quote from: hugy;112634It is doing exactly what it should be doing. These rssi values are the received signal strength in dbi and are a neggative value. So the lower the better. Every time you double the range it should show about 6dbi higher values.
