2m Skip?

[K9CCH]

No, I have dual watch disabled. But B was on 443.825, another local radio club repeater.

[W2NAP]

Interesting... I must have lucked out with the Baofeng I received then. Standing at a transmitter site, less than 20 ft from an antenna array, nary a bit of intermod.
.

im sure if you dig a bit, you will find problems.

Mine has great tx audio, another guy in town has one has totally shit tx audio.
rx on these things are as wide open as a barn door.
as for intermod what was the tx site you were standing next to? was you on the same band as it was?
like I said APD here uses 453/458Mhz if one of the cops or I am very close to the tower and I am on 440 Ill hear them. If I am on 2m and get close to another 2m repeater site Ill hear the other 2m repeater

I was standing on top of Buffalo's city hall, which is a transmitter site for 3 of the 5 BPD repeater systems (On the UHF band), Buffalo Fire (UHF), and I do believe Buffalo DPW (VHF).

I have an alternative theory: Was your B VFO on the actual fire frequency, while you were scanning, with dual-watch enabled, but VFO-A locked in for xmit? Which would make it so the scanning stops when something comes in on VFO B, while keeping your xmit VFO on A.

I have seven Baofengs and intermod has been an issue on only one of them, the UV-5RA. The rest have been clean.

Yeah, I know. Seven HTs is stupid. I hear that every day at home...

Do you have it set on wide or narrow FM?

[W7XF]

I always use narrow FM. In fact, although I have a Wouxon, at the hospital (Mom got her new knee yesterday), I fired up the HT...mind you hospitals are full of RF ESPECIALLY their VHF paging systems, and all the EMS repeaters...nary a bit of intermod. and EMS here is on 450 MHz, doctor's pagers on ~153 MHz.

[kb2vxa]

On WFM volume on all but broadcast signals is so low you can't hear it.

I wonder what the first IF of the Baofeng is? If not intermod, this could be an image, too. I can't find any reference to the IF frequency - that would determine the likely 'image' frequency. The intermod rejection is only rated at 60 dB, so that's not miraculously high.

Good question...

Here's the detailed schematic: http://www.uv3r.com/images/Schematic-Baofeng-UV5R.pdf

Maybe someone can convert that latin into an IF? I can't, beyond my skill level.
