    Very interesting technique, and so easy to use. I’m in the process of setting up and end-fed antenna (40 meter primary band, 49:1 unun) in my yard in Seattle, WA and thanks to you I now know a very good way to test its performance. Thanks very much, Peter. 73 (KK7CSC)

    A very practical video, Peter and crystal clear as usual. I find that on my Icom 9700, even dialling my output power down to zero, give an output of around 15mW, which on couple of occasions has been enough to generate a reply, so for me hitting the Fbkin button was needed! 73, M0YZT

    Hello Peter. Gosh, it looks like you have a problem with the LCD display on your 7300. There is a line at the top . I bought my 7300 from your shop with the first batch that you received...I think that was March 2015. I was so impressed with it, that I bought a second 7300 six months later. I have had no problems with either of them. That LDG 49:1 looks like a handy thing to have...and cheap as chips. I have 1 KW 49:1 transformers for my EFHW antennas at home. But I think I might get one or two of those LDG ones for portable ops. 73 5Z4J, ZS5J

    I tried this when the greyline was at my QTH. The RBN showed the 40m going east and the 20m going west, within minutes of each test. Expected, but it was rather striking.

    You need to send pretty good Morse cide but if generated by radio that should be mo problem. You must send in the CW section of the band ie ie near tge bottom. Reports take several minutes to come back.

  • @BennyCFD
    @BennyCFD2 жыл бұрын

    You can also get how much your antenna is getting out is by looking at the PO meter while transmitting. If you're set at 100W and the meter says 100 you pretty much transmitting 100W. If the PO meters shows 50W you know you're loosing power somewhere. Non resonate antenna, line loss, bad SWR or a combination thereof.

    I'm not sure about that. I've got it programmed into my 991 (not A) and it works. It has five memories for morse strings which can be sent in the same way. Look in the manual under CW and then contest memory thingie. It's the second bit under "Text".
