70 turns 2" diameter over 4" length would be 100 uH, and with an air core and #16 magnet wire would have a Q of about 200 or so. That's 1000 ohms impedance, a few hundred thousand ohms parallel resistance, and the dissipation would be less than 1 watt at 1500.
Or 38 turns over 4 inches on a 4 inch form. You could use #12 wire Teflon insulated, and have a Q of maybe 300 or so. Again less than 1 watt heat out of 1500. Personally, I'd use #12 or 14 Teflon on some old PVC pipe. 73 Tom _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw? BK
