Hi,
I would like to complete my review of Yaesu FT-1000MP Mark-V with some oscilloscops waveforms. http://www.astrosurf.com/lombry/qsl-...0mp-mark-v.htm Could someone provide me a dump from oscilloscope showing a CW keying of the first 2 "dits" in QSK mode (60 wpm) one showing the key closure, the other one the RF enveloppe (at 100 or 200W out, 20m band) ? A jpg file of 200 pixels high is enough. Of course if the image is published your (c) will be inserted too, as usual. Thanks in advance 73 Thierry, ON4SKY |

Unfortunately I can not. However, it is noteworthy that there were many atrocious CW signals on the bands during last weekend's ARRL CW Contest. Some of them occupied more than 5 kHz of bandwidth, with their clicks and spurious signals above and below the primary transmission frequency. It would be interesting to know what equipment they were using. The majority of them came from stations in Hungary and Slovenia. 73 de G3NYY -- Walt Davidson Email: g3nyy @despammed.com We certainly had our share here stateside Walt. Hope I worked you.

![]() If you have the radio, I have the scope. Email me and we'll take it live over the air - assuming you can get a signal into the Boston area. Examples of recording of CW waveforms so far at http://www.qsl.net/wd1v/756cw.html 73, John - WD1V |
