Hello,
I have just gotten my radio license and someone gave me an old
hammarlund receiver that hadn't been used in over 25 years. I used a
variac to bring up the power slowly, because I was told that the
capacitors needed to be reconditioned. Everything seemed to work fine
and I was able to pull in some transmissions with a random wire
antenna. I don't have a transmitter yet, so I am hoping to just use a
longer random wire antenna, laid along the attic until I can get money
together etc. My question is probably dumb, but I was wondering if
there is an "optimal length" for a random wire antenna for hf?
THanks for any help you can provide,

well the questions is good enough for what?
1sure it is a good start
2 optimmum lentgh well Id say yes and know some od multiple of he band
you want to hear most is like a good lentgh so you might want about 3
(or 5 or 7) half wavelenghs for 20 m for the and if you have room 3
half waves for 40 or 80 at night
3 I am not familair with your model reciever if is odd enough it may
have AM cap which would be VERY limited if it doess SSB it is likely
ok

If a "random" wire has an "optimum" length, then
(it seems to me) it is no longer "random". miki.
