I aligned my TO today.
Pretty happy with it. BUT why is the following happening?
Listening to Voice of Radio Russia 31 Meter Band according to web it is broadcast on 9.840 It is coming in at 9.780 on my radio dial
Yet when I inject the 9.840 and 9.780 frequencies from my sig gen monitored output with Freq Counter, the Dial is right on.
Am I trying to cut hairs ??????
Any members care to tune in 31 M Voice of Russia and see what your dial comes up on ??
Thanks

They may be transmitting on 9.78 and 9.84

I kn ow the numbers don't add up tight, but it sounds like you might be getting it on some kind of image frequency.

According to this site, which I've generally found to be reasonably accurate, Voice of Russia broadcasts in English on 9560, 9665, 9800, 9880 (listed as digital on another site), 9900, 9900 & 9955 (relay WRMI), depending on the hour. http://www.short-wave.info/index.phpThis shortwave website I've also found to be reasonably accurate, leaves out a couple of the above frequencies: http://www.eibispace.de/dx/freq-a12.txtI have no idea why you're getting Voice of Russia on 9780. It's possible the temporarily changed frequencies for some reason. I know when I checked their actual website, the page that is supposed to list frequencies in English comes up a a non-existent page....

I am finding exactly what you have posted.
But the Web site I loooked at listed it as being Broadcast at 9840
Do they broadcast at what ever they feel like at any given moment ????

Shortwave can be an odd duck at times, but your hearing something and that counts for a lot. If you want to check the dial alignment the signal generator cant be beat, If I were confident that it's working correctly, I would trust it. If you want to check it with a known broadcaster, I would go with Radio China International. Today, with most countries dropping shortwave in favor of internet broadcasting, RCI has been doing the opposite. They broadcast over several frequencies, through out the international bands, with one of the strongest, and most reliable signals (in both frequency and time). The VOR is very good, but as mentioned above odd things happen on the shortwaves, bands are reallocated (ie. 7.100 to 7.200) and seasonal propagation changes often bring about frequency changes in order to reach their target audiences. Just recently, WBCQ went from their 20+ year frequency of 7.415 to 7.490 due to interference, they were notified by the FCC days before the change was to take effect, and this sort of thing happens often, so only the most up to date web postings will be accurate. If you want the most up to date "spots" you can't beat Glenn Hauser’s World of Radio, here is a link from the May 3rd show: http://www.w4uvh.net/wor1615.m3u He mentions some oddities straight away.

[quote="W2CKL"]Shortwave can be an odd duck at times,
Thank you I think that has answered my concerns. My sig Gen and Radio Dial are spot on, so after listening to the link you so kindly provide I am at ease now.
New to Short Wave listening so this is a huge help/
Thank You Bob T.

Another addition to your SWL station is a good aerial attenuator. If you install this close to your radio, when you get two very close signals, and want to separate them in terms of strength, (incoming) you can make sure the radio is not producing the artifact.
Also some radios 'pull' on very strong stations, that is change selectivity as AVC changes.
If there are two dial points for a given station on SW, you can be sure they are probably not beaming in the same direction.
