thUndeadMod v3.4 - openLRS S**T just got real :)

Hi Mihai,

Just loaded v3.3 and don't get RSSI voltage changes on pin7 (channel 7) ??

Nigel.

what hw version are u using ?

pin7 for v2 hardware. rssi should be on pin 9 for v1 hardware I think.

Mine is v1 hardware - didn't realise it was different output for different h/w.
I'll check again later...

Hay guys, this all looks and sounds great, the thing that puts me of, is every time I look at these posts, my mined is switched of with all the scents.
your tests and antennas are great Splashy, are you going to put up a post on how to make them, if I thought that I could get a safe 2 to 3km out of this system, I would jump on board, but electrics puzzles me and I think I would end up, not being able to get it working properly and wast yet more money.

I can make you a couple of antenna if you like.

I got some 0.8mm MIG welding wire, RG58 SMA connectors and a snake set for a Easy Star.
I solder a length of the wire onto the SMA then very carefully measure 163mm from the edge of the SMA connector and cut the wire. I then put on the inner snake so it goes right up to the soldered bit and cut to length. Then the outer snake and cut. Finally I put some heat shrink on the top and where the snake joins the SMA connector.

It is not a difficult job if you have the right components and the right soldering iron with a fine tip.

thanks mate, that's kind of you, I guess the making of them isn't a problem, it's just getting my head around it,  I have made my own clovers and thy came out great, but I found pictures of the procedure before I did it.

How about a swap .. I need a 5.8 Ghz clover. I will swap you the two 459 Mhz for a 5.8 Ghz clover. Don't worry if you are not set up to make these at the moment, just pm me your address and I will send you a pair of antenna.

RSSI out does seem to be on pin9 (ch 9) on v1 hardware.

I connected a little meter to display from 0 - 100 measured in percentage of RSSI signal.
I also used dummy loads so I didn't have to walk more than a few metres to see the signal drop away.

Click the pics to go super-size!

Full Tx output



No Tx output



Somewhere in between



Before you ask, the meter is this one

Just need some spare time to do a range test with 1/4 wave antennas connected.

I don't need a antenna yet, so don't worry about sending me one yet, but I do have the stuff to make you a clover, send me your frequency and I will make you one up, I haven't got any SMA, but i'm sure you could put one on.

Cool, and bookmarked the screen :)

[Coyote]

Deleted, RSSI fine, Telefly OSD not reading it right ??

[Coyote]

Ok, all RSSI`s check out fine. Has anyone done any range tests with dummy load on tx by any chance, to compare too ?

Hi

In your first post when you refer to v3.3 it says 459mhz band fixed. what was the problem before?

Thanks

Brett

It was an error on my part from the initial frequency steps/spacing.
They were set at 50kHz and are now set at 10kHz - keeps the channel hops inside the allowed frequency on 459MHz ;)

Could this lead to reduced range? On the DIY boards I have made I can only get about 750m with one line of trees in the way using a DIY 1/2 wave on the TX and a 1/4 wave on the RX.

Many Thanks

On any version of the UK 459 firmware before theUndead's v3.3, then yes, it's possible as some of the frequency hops would have been above 460MHz.
Even so, 750m seems a bit low range.

Try with Mihai's v3.3 firmware.

hey guys :)

@Nigel: cheers for the rssi tests :) looking good.

@ghost2212: people are getting between 2.6 and >3km with the current firmware so something might be wrong with the diy gear :)

@everyone else: keep the range tests and good news coming :D
