[digitalradio] ALE and protected frequencies in the USA
I have received three emails in the past 3-4 weeks suggesting that the FCC has an application to protect certain HF frequencies and reserve for exclusive ALE use. Two emails also suggest that people operating on ALE frequencies have received emails asking them to NOT use the frequencies . Is this just junk information ? Has anyone else heard from people objecting to others using frequencies commonly used by ALE operators. ? Can anyone verify that the FCC is considering an application to exclude non-ALE stations from certain frequencies ? Andy K3UK
[digitalradio] New SDR available
Hi, all. I'm offering a new SDR, inspired by the Softrock-40 but with some significant improvements. Instead of a crystal LO, it uses two Analog Devices DDS chips, and has 5 selectable preselector filters. It also feature USB control. Anyone who's interested can find the details at http://www.lazydogengineering.com/LD1home.htm and at my blog, www.garage-shoppe.com. 73, Pete, NI9N
Re: [digitalradio] ALE and protected frequencies in the USA
I have head in the past of folks of 'reminded' using the ALE frequencies for other modes is frowned upon. I personally never heeded the advice as I am of the opinion that if the frequency in not in use, then it's up for grabs. I have not heard about any proposal on the table about a proposal to exclude non-ALE station from certain frequencies. I am sure that if this was a fact, the flames wars would already be in progress. This seems to be a festering wound in need of a doctor.

[digitalradio] Generator Interference
Hello All, I live in Colorado Springs, Colorado. We are getting ready for a 4 county mass causality exercise. This last Saturday we were doing some training, antenna work, and testing at the EOC. One of the tests involved was deploying our mobile command post about 30 miles out into the county. We were able to work 2 meter voice simplex without any problem. However, digital wasn't a good. We were using D-Rats and we could see the other stations without any problem. But, when we tried to send a message it would fail. The generator was causing some sort of hash to be generated and it was causing the digital to fail when passing a message. We could go keyboard to keyboard without any problems. What sort of suppression kit could we install on the generator to eliminate the interference? TNX 73, Dave N0EOP 31033
Re: [digitalradio] ALE and protected frequencies in the USA
From the regulations: Sec. 97.101 General standards. (a) In all respects not specifically covered by FCC Rules each amateur station must be operated in accordance with good engineering and good amateur practice. (b) Each station licensee and each control operator must cooperate in selecting transmitting channels and in making the most effective use of the amateur service frequencies. _No frequency will be assigned for the exclusive use of any station._ 73 - Skip KH6TY phil williams wrote: I have head in the past of folks of 'reminded' using the ALE frequencies for other modes is frowned upon.

Re: [digitalradio] New SDR available
This seems like an astonishingly low price. What are the bandwidth capabilities of this device? Can you do 100 Khz, 200 , more ? Does it require a high end soundcard ?

[digitalradio] Re: New SDR available
The better the soundcard, the better the results will be as with any soundcard-based sdr. I use a Creative SB-1090, which you can get for $50 - $80 if you shop around, and I am very satisfied. I have not tried one of the high-end cards, but understand the performance might be even better. --- In digitalradio@yahoogroups.com, Andy obrien k3uka...@... wrote: This seems like an astonishingly low price.

Re: [digitalradio] Generator Interference
What methods did you use to test for the generator interference? Can you give any specs on the generator such as a trailer-ed unit. When was last maintenance done to the generator, and what? I suspect that you have a faulty plug or a bad shield somewhere in the unit. I would also suspect that when the D-Rat is connected to battery or other stable power source there is no known problems. I am curious though to hear more on this as we have been discussing a D-STAR/RAT, but have wondered about the pitfalls and the ability to fix them in the field much like legacy systems!

think someone has had a couple too many ALEs, or wobblys as they are known as in cow country.

[digitalradio] New SDR from Flex Radio
The Flex 1500 will soon be available. The first one has rolled off prototype line and you can see it (in operation) at the Orlando Hamcation if you are going (this weekend). If is a BCB through 54 MHz 5 watt TRANSCEIVER with control, etc. run via the USB 2.0 connection. If it were not for the 5 watt amplifier, it would power itself completely from the USB 2.0 cable. It will be run by PowerSDR 2.0 (soon to be released). It comes with full support for CAT and 3rd party digital programs without the use of cables (both supported virtually). http://www.flex-radio.com/Products.aspx?topic=F1.5k_features The cost is $580 for the time being.
