160 power output

Rich McCabe #252 Have never noticed until just now my LA-1K does not make full power on 160 meters. Other bands seem to be fine. Testing into a dummy load the amp does: 40 input 720 watts 45 input 730 watts 50 input 750 watts 55 input 765 watts How many watts does it take to drive your LA-1K to? 1KW on? 160? Rich kd0zv
Jerry Raia All Messages By This Member #253 Are using 120 or 220? My 7610 drives it to 1KW with ~35w on 220 vac (160m) -- 73, Jerry
Rich McCabe #254 开云体育 Jerry, ? 220 volts ? 35 watts input would give me only 750 out into a dummy load on any of the other bands.? Takes 55 watts to make 1KW for me. ?

Jerry Raia All Messages By This Member #255 I should have added that was into an end fed half wave wire. I just tried it again and it took 40w to get 1100w out of it on 1900.00 -- 73, Jerry

[email protected] #257 开云体育 Rich, I never tried the LA-1K on 160 ( I have no antenna for 160), but just tried it into a 2K Dummy Load in CW Key down for the first time. This is what I show on the LA-1K Wattmeter and also on the Alpha 4510 wattmeter that follows it (both agree on the wattage): ? ??????????????????????? 35 input = 889 Watts ??????????????????????? 45 input = 940 Watts ??????????????????????? 50 input = 1020 Watts ? ??????????? 73, Reid W2HU ? toggle quoted message Show quoted text From: [email protected] <[email protected]> On Behalf Of Rich McCabe Sent: Friday, December 13, 2019 10:12 AM To: [email protected] Subject: [la1k] 160 power output ?

David Jones #261 开云体育 Just erected a 160m EFHW today (turned into an eight-hour day). Did a quick tune (7610, Palstar HF Auto, Palstar LA-1K) this evening. On 1940 with 45w LSB drive I obtained 1250W; 10w LSB drive saw around 300W. ? Dave N3IL ? --? ? ?
