80 meter

I worked YU7U on 80 meter with CW, pretty fast with 32 wpm. But with a little help from CWSkimmer no problem at all. With my own ears I check always if the decodes are right. Hi hi. With the winter season the higher bands are closing down early. That means that I go down to the lower bands. 40 meter is a nice band but very crowded. On 80 meter there is a lot of space available. Enough for CW, JT65 and PSK31. On 40 meter the JT65 frequency 7076 KHz is in the SSB section of the band. On 7039 KHz are a lot of strong CW beacons and other noise. 80 meter is a good alternative for low band operations. The problem for a lot of hams is the antenna space needed for lower bands. Vertical antennas are most of the time insufficient unless you put a lot of radials on ground level. An end fed antenna is possible but you need still 40 meters of length, and that is maybe not possible for a lot of us. I like to work on 160 meter too, but... no antenna for it. Maybe an EH antenna? But that antenna concept is questionable and maybe losses of -20dB.

  1. Hi Paul. I have certainly observed 20 meters opening late and closing early now. As you said, Low-band antenna space can be lacking as it is here. I just accept a shorter radio-day. The YL is getting re-acquainted with me,hi.

    1. Hi Dick, I must admit that I seldom work late at night. In the evening I spent time with the family, watching TV. Maybe in the early morning, I rise at 5 o'clock in the morning. 73 Paul

  3. Good morning Paul, I noticed some good DX on 40m last evening but was unable to make any contacts. I have nothing for 80m other than seeing if I can use the antenna tuner on what I have in the attic. I do use the tuner on 30m and it works out great for me so maybe now that the winter is here I can give good old 80m a go.

    1. Hi Mike, at least you can give it a try. Maybe you can tune it for 80 m. 73 Paul

  4. Hallo Paul, in de morgen DXen ga ik ook doen in de toekomst. Als de nieuwe radioshack klaar is. Nu kan het nog niet. Ik kan met mijn vertikale antenne wel op 160m uitkomen gek genoeg. De loop krijg ik er niet afgestemd. Vroeger gebruikte ik een sloping dipole met een spoel en topcapaciteit aan het eind de mast was de tegencapaciteit, dat werkte uitstekend alleen had ik heel hoge QRN ruis op die lokatie. Hier is dat anders. Je zou je dipool (tijdelijk) kunnen verlengen met spoelen waar ongeveer 22m draad op gewikkeld zit. Je zou het zo kunnen maken dat je de spoelen evt. makkelijk kan verwijderen er er weer opzetten aan het einde of ergens tussen in? Het is maar een idee :-) 73, Bas

    1. Hallo Bas, ja dat zou nog een idee kunnen zijn. Misschien moet ik dat maar eens proberen. Op 80 m is even voor zonsopkomst leuke dx mogelijk. 73 Paul

  5. Hallo Paul,

    Dit lijkt me wel interessant: http://tinyurl.com/chxeppd
    G7FEK 80m Antenna for small gardens.
    Blijkt heel goed te werken, en zeker voor DX op 80m.

    1. Hallo Patrick, bedankt voor de link, inderdaad een korte antenne voor 80 m. Ik heb de link opgeslagen. 73 Paul
