what freq should I try living in tucson az? thanks fore the help smiles Hank - Original Message - From: Bob Camp To: soft_radio@yahoogroups.com Sent: Wednesday, February 03, 2010 7:35 PM Subject: Re: [soft_radio] going to test my sdr with shortwave time clock need some help Hi Canada's time signal is CHU http://en.wikipedia.org/wiki/CHU_(radio_station) They are on 3.33 7.85 and 14.67 MHz. Good for time, traditionally not so good for frequency. That may have changed recently.

That's one way that comes to my mind. Another is that tuning to a side you have both on the spectrum, separated by 4 kHz. Not too good for requency reference, but might allow to compare time standards and propagation delay. 73, Jose, CO2JA PS: You guys are fortunate in the middle of the world emerged land, you can enjoy fairly good signals from both east and west. On this side of the world, the Pacific Ocean is too wide to the west to hear much with so bad propagation nowadays. -- Participe en Universidad 2010, del 8 al 12 de febrero de 2010 La Habana, Cuba http://www.universidad2010.cu
Re: [soft_radio] going to test my sdr with shortwave time clock need some help
HI All of the IF stuff is over in the PC with a SDR. If you have a piece of PC software that will let you launch multiple receivers, it will do it. There are a lot of programs out there for digital modes that will do that. It certainly can be done for AM as well.

can you tell me of a pc software that has this functionality that also allows you to tune via keyboard and switch mode via keyboard? this is needed in my situation. please if you know of anything please let me know Hank - Original Message - From: Bob Camp To: soft_radio@yahoogroups.com Sent: Sunday, February 07, 2010 10:10 PM Subject: Re: [soft_radio] going to test my sdr with shortwave time clock need some help HI All of the IF stuff is over in the PC with a SDR.

[soft_radio] going to test my sdr with shortwave time clock need some help
hello can any one tel me what filters etc I need to do to try to recieve the atomic clock sw station on my sdr? I got a antanna and the parts to make another antana I know its 5 mhz 10 mhz and think its 15 mhz could have swarn they had a 4th freq anyways anything special I have to do or select sw and tune? could use some newbe help Hank
