Unless you have a real radio I wouldn't bother. Is your Royal 1000
working?

''Random length dipole'' makes little sense.

aka 'Doublet' where you have two equal lengths of wire that are not
cut to any specific frequency, rather they are cut to fit the maximum
dimension you have available. Doublets are typically fed with
twinlead and a tuner is used.

An alternative would be a non-random length dipole resonant on several
swl bands without the need for an antenna tuner. See...

I used to have the sloper version of the above. Worked great.

The MFJ 16010 random wire tuner would do well with your sloper; runs
about $49.99...

Say howdy to Martin...

Do you think when I switch from a SWL to a ham band,
I need to switch antenna types? LOL...You guys kill me..

I did not ask to get bagged on by an amateur. Learn to post without

Well how can your receiver work with an antenna made for transmit 8-}

Basically (theoretically) an antenna made for transmit is just as
suitable for receive. This is called reciprocity.

This concept falls apart two ways in practicality:
1. The transmit situation has to handle power the receive situation does
not so for transmit the antenna elements need to be "beefier."
2. A less than full size antenna made resonant may work very well for
transmit but for receive not as well. Less than full size for receive
lowers the antenna efficiency.

twinlead and a tuner is used.

The concept here is that on receive size matters so a dipole antenna
made for the lowest frequency band you want to receive will be a
multiple wavelength antenna on higher frequencies. The only rub here is
that it will not work well on even harmonics so be sure to pick a size
that ends up as an odd electrical harmonic length on the higher bands.
