Bestofferbuy A/V Tx 1.28 actual channel


http://www.bestofferbuy.com/av-wirel...o-p-15758.html

I recently have picked up this setup and was concerned over which channel is actually 1.28. I've read on here most thinking its channel 9 with no jumpers on the Tx. I emailed Bestofferbuy and got a response back a week later. According to them 1.28 is with the jumper on the last 2 pins. (see attached) This picture is straight from the manufacturer.

That puts the Rx on channel 7. My Rx has 0 thru 9 channels, my tx does not have the digital display but uses the jumpers. Now to go about actually confirming this.

That's interesting, it contradicts what's in the manual!

If you can confirm this, let us know! We nee someone with access to a frequency counter that will measure it to know for sure.

Dear Sir/Madam,

Thank you for your inquiry.

Please be advised that the jumper should cover the last 2 node if you want to
transmit at 1.28MHz.

Please refer to the attached for more info.

Kindly email us again if you need further assistance.

Regards,
Joseph Ip
Customer Support

The actual response from BOB. When I meet with the local Ham guys, I'll check around if anyone has the counter.

The other differences are the 12 channel compared to my 8 channel, digital displayed Tx and non-digital displayed Tx, (such as mine), Rx does have digital display

Alright group buy, all of us with these cheapo setups can pass it around to test our frequencies. LOL

Nice find btw. Thanks

This might help. On every reciever I have, Ch 9 is always 1280MHz and Ch 1 is 910Mhz.

Here's some of the best deals I know of

910Mhz 200mW Transmitter $35

12 Channel reciever that picks up 910 and 1280 MHz $36

800mW 1280MHz transmitter & reciever $80 (have not used this one myself)

1280MHz transmitters $45 & $80

Avoid this one for US/Canada as it's fixed on Ch 5 1120MHz

If anyone knows of a cheap ($30 or less) 910 or 1280 MHz transmitter that outputs at least 50mW, please do let me know.

That makes more sense to me, I was under the impression that CH9 on these receivers was 1280MHz. The manual that comes with the Best Offer Buy set supports that as well, and shows 1280 with no jumper anywhere on the pins. With no jumper, it's received on CH9.

Here is the page out of the manual. Just in case you didn't have it. Doesn't really tell you much. Now if you could read chinese it may be of help.
This is from the trans/ reciever set from best offer.com

That was my next step to scan the manual and post it. I'd like to know how everyone gets 1.28 on Ch 9 from that. LOL

A lot of this has to do with the fact that we have different combos here.

Because that's not ALL the pages from the manual. The English section shows that Channel 9 on the receiver is 1.280GHz, here's the relevant parts put together so it's easier to make sense of it...

Based on these diagrams, the picture you got from BOB will have it on 1.200GHz, which is bad!

Now I'm not saying one is right and one is wrong, just that you can't go by what they told you and be positive it's right. Now I can't be positive that the manual is right either... We really need someone to check this for us... I wish I had the $60 to spare for the counter.
