The "Unfavorable DX frequencies" table on 160m - (update 3May2024)


Hi all,

maybe you remember that long time ago I tried to create and keep updated the list with "unfavorable frequencies > the frequencies which are QRMed in some locations or somehow horrible to use...

Unfortunately, this little idea has sunk in overtime…

So now I am coming back with that idea updated 3-May-2024, and I will try to keep it up!

As many of US hams reported in the past, topbanders should avoid frequencies 1810, 1820 and 1830 because on the west coast US commercial radio stations create on these frequencies of the harmonic frequency, they cause on 160m interference up to S9 and prevent them from receiving.

The "Unfavorable DX frequencies" table on 160m (original article 4-Mar-2007)   

Hi all,

from my experiences with DXing on Topband I found that there are some frequencies which are not usable in some DX locations cause of local heavy QRM over there or permanent local BC interfered signals or other problems.

These frequencies are permanently unusable or even unfavorable for DXing in that DX location and its not efficient to calling CQ or looking for DX from that location overe there...

In my oppinion it will be very usefull for all Topband enthusiasts to have the table of that "unfavorable QRGs" available for quick check if needed. This table will be updated as many time as possible.



QRG (kHz)Unfavorable range (kHz)DX-locationComments
18201819 - 1823JApermanent BC QRM in JA around 1820
18181815 - 1821ZLstrong QRM from local GPS correction on 1818
1810   1810, 1820, 1830 USA      west coast BC harmonics                                         interference up to S9


Information about another "unfavorable QRGs" in Your locations are welcomed for sure! Please let me know by email or in comments bellow...

John, ON4UN - SK



Dear folks,

Very sad news just received from the daughter of John, ON4UN

It is with sadness, but also gratitude and pride, I have to let you know my father John ON4UN, has become silent key.

John’s health has steadily deteriorated throughout the year, but in the last few weeks he was home with us where he peacefully passed away yesterday November 9.

Ham Radio, and especially Low Band DXing, were my father’s lifelong passion and always had a strong presence in our house. Sometimes literally, when many of you paid us a visit or a group of DX’ers came over for a weekend of contesting. At other times in the background, when my dad was working on a project or experimenting with new equipment or antennas.

Though I don’t have a call-sign, I very much feel part of the big radio family and always will. I am very proud of everything my father has accomplished together with you, and I am grateful to the many of you who have given him so much joy over the years. We will miss him dearly, but we take comfort looking back on the beautiful life he lived as a member of the wonderful Ham Radio community.

We are planning a digital farewell ceremony on Saturday November 21st and will keep you updated on practicalities.

If you would like to send us a message please mail to ON4UN.SK@gmail.com – John’s old e-mail account is not in use anymore.

In the meantime, you can pay him a visit at QRZ.com where he always kept his resume up to date.
