Re: Hello!
Welcome StalkerRadar. I get shot by your radars fairly often around here as the stateys (NHSP) have 'em. Either the Dual or the DSR, not sure, maybe they have both kinds.
I used to have an ATR which transmitted at closer to 34.9 than 34.7, actually it was around 34.8. Were there older ATRs at 34.9?
On the frequency-hopping/spread-spectrum and tuning issues things...aren't the Gunn diodes in the antennas fixed frequency? There's no way to "tune" or change the frequency of them is there?

Re: Hello!
You can tune the frequency on the gunn diodes by basically running a set-screw in and out of the chamber. It can only be tuned so much though, and the diode works best around the frequency it is rated for. I've played around with adjusting them high and low, usually the power drops off and range decreases quite a bit.Originally Posted by kpatz
About the ATR, it sounds like that one is just a little off frequency. I've never seen any ATR that was pre-set to something other than 34.7GHz. Also, do you know how old that unit is? I'm actually working on an ATR right now that was made in December of 2000. Once I'm done with the flex circuits I'll check the frequency and see what it is, should be 34.7.
Edit: Checked freq, 34.74GHz (within spec)

Re: Hello!
StalkerRadar, welcome to the forum. It seems like you are really helping out us forum members quit a bit, thanks for the helpful info.
Re: Hello!
I don't know how old it was, I sold it a year or so ago...
I thought Jimbonzzz (one of the tech gurus here) said one time that the very first ATRs were 34.9, then Stalker changed to, and standardized on 34.7 later on.

Re: Hello!
No problem at all, I'm happy to help and find all of this stuff very interesting.
I just spoke to the head of engineering who was in here talking to my supervisor, I asked him about that and here is about what he said. "Like you, I've only been here a couple of years but it is possible some of the earlier models were set to different frequencies and retained the same functionality".
Looks like it is possible, but unfortunately it seems like solid information on that sort of thing is hard to come by here.
Re: Hello!
Welcome to the forum. Out of curiosity, are the traffic sensors that you guys have been making lately pulsed K-band radar?
Re: Hello!
Are you referring to the S3 antennas?
Re: Hello!
I don't think so. The one I saw was a cube shaped k band radar antenna that appeared to be pulsed. Unless those S3 antennas are cube shaped?Are you referring to the S3 antennas?
Re: Hello!
Are you also stalkervision on youtube?
Re: Hello!
Sounds like a standard sport or basic. We don't have anything pulsed, the oscillator is always on or off.I don't think so. The one I saw was a cube shaped k band radar antenna that appeared to be pulsed. Unless those S3 antennas are cube shaped?Are you referring to the S3 antennas?
