+20 supposedly from the Miaoli site at 1kw. Pretty strong.

1254 S5, QSB, sounds like hymns, can't make out language. Bursts of data on frequency.

The Atom based sticks don't have the horsepower. The i3 Intel sticks do. Unfortunately, the Intel sticks with anything above Atom use a micro fan that runs continuously.


I can attest that the Azulle brand PC sticks running Win10 Pro, 32 bit, are very good for single purpose use, like decoding ACARS, SafetyNet, FleetNet, and ADS-B, since the signals are narrowband and defined. Stick a RTL-SDR on it and go.

S7 lite fade in S. Texas on vertical. Compressed. Decent sound for AM PR.


The host audio is hotter than the music and has more dynamics.

10/11 meters / 2135 UTC 29250 FM repetitive chirp
« on: May 30, 2021, 2139 UTC »
a very brief chirp, sounds almost like packet, but not. Repeats on a 15 second cycle. Transmission is maybe .25 seconds. Signal is not steady. Sometimes it fades off for a couple cycles then comes back strong again. S3 is about the highest.

I would expect a metal case at that price point

1123 - station ID
1124 - S5- S9 QSB, decent signal considering

Equipment / Re: BCD436HP CB reception tells me I'm on a diff freq
« on: January 30, 2021, 1610 UTC »
If the two CB walkie talkies can talk to each other when set to the same channel, it's doubtful that both would have the exact same failure causing an identical shift. I'm voting for spurious emissions or front end overload from the talkies.


Which GE talkies are they?

10/11 meters / 11m open to ? Lots of traffic on 27095
« on: January 30, 2021, 1603 UTC »
sounds like I'm picking up a ton of control signals, several stations at the same time. Only phone activity so far was 27015 in Spanish.

2240 - deep fades but S9 peaks. Great audio - 'Do It All The Time'

[size=78%]AM - repetitive Blazing Saddles clip playback [/size]

screwed with one for 4 hours today and could not get it down lower than 2:1 SWR best case and only on the lowest part of the band. Also, how the heck does it mount? The diagram shows it stuck on top of a pole in line with the pole. Never seen a CP antenna mounted like that. I stuck it on sideways like it looks like it is really supposed to be, but not geed results.

Equipment / Re: flex 3000 for a transmitter?
« on: November 04, 2020, 2029 UTC »
KE9NS PSDR version will allow the 3000 to go 10kHz wide. It will sound clean and flat. The PSDR audio processing will sound OK on music, but it really isn't designed for that. Better to use an external multiband broadcast processor if possible. You can feed it into the Flexwire line level input on the back.


Duty cycle? While the 3000 has good cooling, based on my own experience with digi modes running 40 watts, depending on the band, it will probably not hold up to continuous transmit despite what the specs say. At a 1.2:1 match on 20m, the temp rises to 70c pretty quickly and the fans run full speed during one JT65 cycle. Broadcast program audio would be different but with processing for loudness may behave the same as continuous tones.
