Re: Topband: Heathkit SB-1000

Jim, If I remember correctly placing an additional transmitting type cap across the units load cap did the job. Don't remember the value I used. My guess 100 or 200 PF. I used a cap I had in the junk box. You will need to remove the cap in most cases for the other bands. Rich AA2MF Sent from

Well not to appear to be entirely disputatious we should carefully consider KP4KE CQ WW 160 meter QRP entry in 2005 which he said he accomplished with 4.7 watts to a "magical antenna" which he called a "double bazooka" at 60 feet both for RX and TX. While claiming to work 42 countries with

Reversebeacon can shed some light on this today but data does not go back to 2005. I always chortle at the claims of power output that go to such high precision like "4.7 watts". Reminds me a lot of when Jim burned down Louie's apartment in the TV series Taxi, and Louie is trying to come up with

Bob, I am not sure if you are aware that KP4KE allegations and confirmed actions are legendary. People have operated from his station and never had the same result (can't imagine why). Also, KP4KE was legendary for self spotting. He asked me to spot him one year in the ARRL DX contest and I

I joined this reflector not quite a week ago. I am new to 160 meters though I have been a ham since 1967. As I stated before here I was in the 160 meter contest looking to work all states. I got pretty close by working 45 of them. Of course I do need Alaska and Hawaii but stateside I need

If you see no dip in the PA current then check and see if the tuning capacitor padding capacitor is open or disconnected. Check the leaf on the band switch that corresponds to the `160 meter position which also switches in the additional fixed capacitor and make sure it is making a good

SOmetimes many amps require additional padding on 160m Add another 200pf to what is already there for 160. It is necessary to put a brass washer around the contact on the wafer that adds in the padding cap on 160m. See photo of Al-80A on internet to see where it needs to go. This is a must
