Broken 600mW VTX :(

Had a little crash yesterday with my mini quad into the grass.
Don't know how it could have happened, but it broke off my Antenna :(
This will also probably have fried the VTX, as they don't like to have power with no antenna.
It was power for about 15mins while I was trying to find the quad.
No sure if its fixable. Waiting for an answer from ImmersionRC.

I did this to my Immersion 600, in fact 2 of them.
A friend has soldered a short pigtail with the connector on the end on one so I can remote mount the antenna on it.
I don't have it back yet but he says it seems to work fine.
I will let you know how it goes.

I do hear what he is saying about running it without an antenna, it can do damage to the electronics.
Mine ran without for probably a couple of minutes and I still had video so I am hopeful that range won't be reduced.

I spoke to a guy that lost his antenna for 10 mins with power.
His unit dropped from 600mW to 100mW :(

@Graham,
Glad I got one that worked from new then ;)

Bummer. Cooked something. Is it worth repairing or just going to get a new one?

I have one of these I will be selling soon. Exact same one. If shipping isn't crazy from US to Spain might be worthwhile.

I purchased a 1500mW TX during the black Friday sale.

Will do I will probably swap it out this weekend. PM me your address or whatever I need to know to figure out what shipping would cost.

I've been investigating what could be wrong with this, there's an amplifier chip in it, the HMC406. Basically a high frequency transistor amp... This is probably what's blown on it. It's a small surface mount chip, would be simple to replace if you can solder smd parts. Which I do everyday.... Just need to source them now...

I just shipped something to the UK from NY. Not too bad. About $10-12 for a fist full of servos. I had to oversell the weight because of the customs form needing individual weight on each item and I could't use fractions of an oz. IF I could have had the true weight on there (2oz instead of 5) it would have only been $8ish I think.
