    Line of sight had nothing to do with you working JA on 6 meters. That's all propagation which I am sure you already know. When 6 is open it does not take a lot of power. Do you know what the...

    I would say Tropospheric ducting was your friend that day. Of course with a 19 element beam your EIRP was not QRP. Shows my point it's in the antenna.

    I think this thread is a good idea as I primarily chase DX. A lot of variables make long distance DX harder or easier on some days. Your band, mode, propagation, antenna, time of day and power all...

    Yes it should be very repeatable. I would say tune up on your band and note the settings after you get it tweaked. Then put a sticker on the amp with those setting for that band. It's possible...

    flboy,

    You may already be aware but if not W8JI has some excellent amplifier documentation specifically for the 811. Most important item to remember is to only tune for about 3 or 4 seconds and...

    I am surprised that no has mentioned one of the most important tools you will need. A dummy load. A dummy load will let you test your radios against a standard known 50 ohm load. You can test...

    I believe the IC-7300 does have an internal sound card. You should be able to use that with FLDIGI.

    NOT, AND, OR, NOR are logic state indicators for binary devices. They used to be discrete circuitry but today they are on SMD chips.

    The current tests are really easy just because it does not...

    Short of the weak signal modes CW is still the most efficient means for amateurs to make contacts. To ignore it means missing the best dx. Even if you cant copy you can use programs that can.

    I briefly looked at the manual. The send jack and ALC jack can be used to control a amp. Send jack goes low when xmit.

    KN4BFQ,

    Techs can operate phone (AM,FM,SSB) on 10 and 6 meters as well as UHF. 160 - 12 meters is out of the band for phone.

    You will need a tuner with a balun as the w3edp antenna is ladder line fed. It is not an efficient antenna. If you can hang this you can hang a dipole or OCF dipole.

    See the article below...

    Your post indicated you have large trees. That is where i would be looking to hang a dipole. If you use insulated copperweld you can get away with 18 gauge. It will be hard to see.

    I find RIT most useful for working split. Set the RIT to the DX freq and then tune the VFO to where he is listening.

    The Icom 7300 is a step up from the Yaesu 450D. That being said the radio with the better antenna will make more contacts. Spend your money 1st on antennas.
