Hi W4UAV,
There is no interference with the original antenna!
I am preparing to order a set TX / RX :)
Do you think Foxtech 32channel 5.8ghz 600mw is better than ImmersionRC 600mw ?

There was a little static. You could still fly with that signal even with the stock setup. I was on my way out to around 2 miles but the ESC overheated and shut down. I am going to try circular polarized antennas next.
As for the IRC 600mw, I had a bad experience with the first generation IRC 600mw 5.8ghz Transmitter. It had no range at all. From what I understand the second generation with the nexwave module is supposed to be better, I havent tried the second gen yet. I do want to try the IRC system with this receiver and see how it works it is supposed to be compatible with all IRC frequencies as well as Boscam and Walkera.
So far so good.

Would you all say this is the best 5.8ghz combo available to date? I'm just getting into FPV and need a video setup for my Tri-copter. I'd like to be able to freely explore above the tree-tops, but I can't afford 1.3ghz + UHF yet. Figured I should just start with 2.4ghz + 5.8ghz video. What do you think?

The ImmersionRC 5.8GHz 600mW transmitters don't use our NexWaveRF modules, that's reserved for the receivers, where the sensitivity, and out of band rejection (2.4GHz RC!), is better than anything else on the market. Furthermore the 600mW design has seen two iterations, the first one, that was discontinued almost two years ago, and the current V2 transmitter which is about 40% smaller than the previous version and currently still is the smallest and most popular 5.8GHz transmitter to date.

The reason for its popularity is clear: unparalleled image quality, durability and range when used with our NexWaveRF receivers.

P.s. you're not flying with a #16 keychain camera as your flight camera I hope?

You think 'ImmersionRC 5.8 ghz 600mw "is better than" Foxtech 5.8ghz 600mw "?

Sander - I'm using an immersionrc 600mW 5.8GHz vtx (version 1) as a relay from my 1.3ghz ground station to my aviator goggles, which have the new 5.8 Nexwave receiver board in them. I'm having issues with screen tearing in bright scenes with this setup but it's clear if i take video with a cable directly from the receivers. Could a new V2 version 600 mW immersionrc vtx help with this at all? Cam is a pz0420 on most of my aircraft - I've seen this discussed before that it is a problem with crappy sync levels on chinese cams etc. My old 600mW vtx has been through some crashes.

I have ordered a new irc vtx to actually test it, as well as one of these foxtech 32ch ones.. But I thought you might have a prediction :)
Thanks

That shows I havent been keeping up with the latest IRC 5.8 gear. If you would like to send me the latest one and a receiver to test side by side with the Foxtech TS832/RC832, that would be a great comparison.;)
Thanks Sander.

I've gone with the Boscam 832 from HiModel and the TBS Receiver to insert in to the Fatshark goggles.

Is this 32 channel combo necessary if you are starting from scratch? How useful is being able to switch channels at the field? I mean, if someone is flying on your channel, how would you know unless you ask them, w/o shooting them out of the sky? I'm wondering because the field I fly at is popular with the fpv crowd.

If you switch on your receiver while someone else is on 5.8ghz... nothing will happen. It is a receiver, no RF is generated to interfere with them,;) but you can check what frequency they are on and go to another frequency on the 5.8ghz band far from them and fly. 5.8 ghz is popular due to the small size of the antennas and popular with multi-copters and aircraft using 2.4ghz for control, there arent any issues like that of 1.3ghz and 2.4ghz (I use a filter) So no it isnt necessary. It would be nice to have 32 channels to choose from.

W4UAV, you almost made 2 miles on stock antennas? I imagine lost of trouble in regular flying if you don't go CP. How warm does the VTX get? Is it true 600mw? VRX as stable as RC305?

W4UAV
25th July 2013, 03:40 PM
I was headed to 2 miles, on that flight I made it to 3/4 of a mile when the ESC decided to overheat and shut down. I will be conducting another test flight this Saturday weather permitting.

This guy is always good for a laugh. His tests shows the new 600mw and the olde 200mw doing about the same in a range test!?

My current FPV set up:
F450 NAZA lite GPS
Sunnysky 2814 700KV
APC 11x4.7
Turnigy NanoTech 6000mah
Skylark Trace OSD
Foxtech TS832 32 channel 600mw VTX with IBC Cloverleaf w/ RPSMA Adapter
Foxtech 32 channel diversity monitor stock rubber duck antennas,attached to (mounted) on my futaba
Futaba T8FGS
GoPro Hero2

Just did range test as FPV stuff recent added,
I did 1.2 miles when video just started to get crappy, as I began to turn around, at certain point, I completely lost video for second, but lost my RC, regained in about 3 seconds (going into failsafe), and flew back.
Up to 1 mile the video looked perfect, even up to the 1.2 it wasn't horrible.
Some issues I had was that the sun super bright, was almost directly overhead, and I couldn't turn my body completely towards the aircraft, because I needed to be at least sideways to block the sun.
I noticed later that my antenna on my RC TX was down flat against the transmitter, (that didn't help)
Also this isn't the ideal setup with the VRX mounted on the RC TX, RC TX will suffer, plus some interference into the VRX.

Even with all that, and rubber duckies on the VRX, I was really impressed with both the performance of the VTX, and VRX.

I think just as is, im good for 1 mile with great video, I will be adding SPW on VRX, just adding that should make a nice difference.
With the VRX on tripod with helical, and SPW, would get some great distance, I imagine.

1.2 miles with Futaba 2.4ghz is just about right, actually thats pretty good.

You need the cloverleaf on the TX and SPW on the RX to work the best, just using the SPW on the RX won't help, both need to be circularly polarized antennas.

Thanks Mike, I already have cloverleaf ibc with rpsma adapter on vtx, im wondering how much is lost using an adapter than straight in connector?
I might try these guys out, anyone have any experience with any of there antennas?
Quadframe is just distributing them they are made by a guy in Poland I think.

Wow I thought I could eek out a little more rc control on 2.4, my video is out ranging my control.
Eventually I'll pony up for ezuhf.

There is a tiny bit of loss at each connector, however most loss is measured in the feet of coax even at 5.8ghz. Ive never used their antennas.

Mine should arrive this week. Then i will first just compare my old RC305 with the new 32ch Rx, to make sure, the new one is fine (i know some guys that ordered 5 new RC305 Rx and only 2 of them had similar range to my old RC305...the other ones gave much worse range).

After that, i will open the 32ch Rx and try to find out, if i can hack it to get RSSI out. If this will work, i will order a second Rx for Diversity.
Finally i will then change my wires/connectors in the plane, so that i can hook up that new 600mW Tx.

I just got this tx, and I see no audio input?

How can I use this with my MFD tracker?

Mine arrived and my old RC305 has beaten the shit out of this new 32ch thing...

http://dscfpv.wordpress.com/2013/08/...eceivers-crap/ (http://dscfpv.wordpress.com/2013/08/26/all-new-foxtech-receivers-crap/)

My 32ch RC832 only gives me 50-70% of the range i got from my old 2.5 years old RC305 receivers and the RC832 of a flying buddy has the same, reduced range. Even new RC305 receivers perform worse than my old ones.

And another buddy has tested the 32ch Tx with surprising results...on some channels it only produces 30-40% of its 600mW Power....on some other channels it does 80-90%.

I'll sell my set and give ImmersionRC another try.

Goes from approx 5700-6000mhz, antenna you use will be tuned better to a certain range as you go outside that youll be putting less power out and more power reflected back.
I dont have a meter to check that high though, maybe someone else can chime in, on 5.8ghz, how much swr changes through the spectrum, and with what antennas, vtxs.

Hi !
I dismantled the receiver and attached a logical analyzer to the SPI lines, to see how the RTC6715 chip is set up. Based on the datasheet (http://www.flypix.co.uk/shikra/ftp/RTC6715-DST-001.pdf) it is possible to calculate the receiver frequency.
Lets see :



RC832
FR ch1 ch2 ch3 ch4 ch5 ch6 ch7 ch8 ch9
1 5865 5845 5825 5805 5785 5765 5745 5725
2 5733 5751 5771 5789 5809 5827 5847 5865
3 5705 5685 5665 5645 5885 5905 5925 5945
4 5739 5759 5779 5799 5819 5839 5859 5879
PARTOM RX 5719 5739 5759 5779 5799 5819 5839 5859 5879
1.2W TX 5720 5740 5760.2 5780 5800 5820 5840 5860 5880

I also checked the 1200mW video TX and the PARTOM receiver which comes with it.

Conclusion : The Immersion channels are not precise. They have 1Mhz difference. In fact, the RTC6715 based receivers are not capable to set to even Mhz frequencies.
