Now test on a dummy load or ham bands into an antenna. You should be able to key up on 7.200 MHz LSB.
If you find a TKM-707 for under $300, do the . Skip the 200W temptation and the advanced IF tap unless you love tinkering. For under $400 total invested, you’ll have a rugged, high-power HF rig that will survive a lightning strike better than any modern SDR. kenwood tkm707 mods
Warning: The further you drift from the 2-meter band, the more the internal low-pass filters and tuned circuits become inefficient. Transmitting at 160 MHz (for example) often results in high SWR and overheating finals. Now test on a dummy load or ham bands into an antenna
He hesitated. The TKM-707 had saved him twice—once in a whiteout, once when the main engine died and he needed a tow. Respect. But also, it was just atoms. Skip the 200W temptation and the advanced IF
He tossed the rest overboard. The Kenwood sank slowly, trailing a thin smoke ribbon, and for a second, a ghost transmission broke through the ship’s speakers: Jack’s voice, time-delayed by the ionosphere, saying, “Godspeed, you madman.”
