You are welcome detectoman.
Next weekend I will post proposal of one possible way of: how to build combined spiral/telescopic antenna (I am out of my home at the moment - till Thursday I suppose).
To clarify "tight" drawing: spiral antennas are connected between (Q1, Q2) emitters (respectively R6 of receiver) and ground. So this way representing by electrical symbol:
Spiral coils inductance for 1MHz about 150uH.
Telescopic antenna can be replaced with piece of aluminum (or Cu) hard wire or small tube of adequate length for chosen frequency, par. example for 1MHz length is 150mm (not very critical).
Spiral antennas of TX (L1 and L2) are anti-phase wound, for zeroing (phasing for RX spiral antenna is of your choice - more will be explained latter with antenna build suggestion).
