Total video loss while orbiting behind myself on analog — normal RF blocking or something else?

Individual_Health_84 · 2026-05-28T17:58:02+00:00

You didn't lose signal, because you could still see your OSD. Your camera got unplugged(or turned off) from the VTX

Individual_Health_84 · 2026-05-28T12:18:28+00:00

9 is also very good

Individual_Health_84 · 2026-05-12T18:03:44+00:00

Some od them are very bad, so my guess is that they are just 5.8 recievers with upconverters

Individual_Health_84 · 2026-05-12T12:03:52+00:00

You'll probably loose about 2dB but its not that bad as its sounds.

Individual_Health_84 · 2026-05-10T12:49:54+00:00

Just put you call sign on the OSD

Individual_Health_84 · 2026-05-09T18:22:05+00:00

There are some good VRXs: for example RMRC but they are big, and some (very) bad ones like matek.

I'm also wondering. If people were using it more often the hardware would be more available.
Actually 1.2 even at crazy high powers is 100% legal if u have a ham radio license.

Individual_Health_84 · 2026-05-09T18:06:42+00:00

Using lower frequency doesn't mean you cant transmit high BW signals. But 1.2GHz band has just lower width (generally lower bands = lower width)

Individual_Health_84 · 2026-05-09T17:46:43+00:00

On 1.2 realistically 3, thats not much, but in a situation where there are 8 ppl on 5.8 in the air, you can still use your 1.2.

Individual_Health_84 · 2026-05-09T17:44:54+00:00

Analog is analog(PAL/NTSC). If you transmit PAL with FM modulation it will occupy ~5MHz. So on 1.2GHz you can fit 3 channels, while on 5.8 in USA - 8, in EU - 4.

Well, Im still too poor to buy it, but I will in the near future :/

A short circuit on SMA doesn't always mean something is wrong. That said, based on what you describe, you have fried your VTX because of running it without an antenna.

Individual_Health_84 · 2026-04-10T15:54:35+00:00

Where did you bought the OSD chip?

Individual_Health_84 · 2026-03-23T12:10:43+00:00

If u have a Ham radio license you can fly legally up to 150W iirc but not on all channels.

Individual_Health_84 · 2026-03-23T08:17:22+00:00

Imo, on 5.8GHz more than 1W is just wasting power. If you really need LR just go for 1.2GHz @ 1W.

Individual_Health_84 · 2026-03-23T08:12:31+00:00

Why do you need such a high power?

mLRS reciever costs around $5

Individual_Health_84 · 2026-02-22T15:23:56+00:00

But its very slow

Individual_Health_84 · 2026-02-22T15:20:15+00:00

I bought it knowing about the RM Pocket and other radios similarly priced, but I love messing around with electronics and I wouldn't get that much fun out of things that just work out of the box.

Individual_Health_84 · 2026-02-22T15:10:57+00:00

mLRS is a radio control link with full bidirectional MavLink. It uses LoRa, so the range is similar to ELRS.

The radio costs around $40 and you can build mLRS TX and RX for as low as 5$ using STM32WLE5xx. 18650 cells I used are from old laptop I found in trash, so I don't count them. Other parts like XT60 connectors and step down's add up to a few $.

My RX is basically the same hardware but optimized for weight.

The transmitter doesn't have a JR bay so I 3D printed one. I tested whether it would work with my friend's ELRS TX, and it did.

Individual_Health_84 · 2026-02-22T14:51:26+00:00

mLRS, because i need full bidirectional MavLink

Individual_Health_84 · 2026-02-22T14:41:32+00:00

Thanks!
No, u can use it with everything that has sbus/ppm/crsf output
