Magnum IB

[plboy]

I have done a Magnum 4 years ago
Which type of coil will be good for this shematic to be stable
can I use a DD coil

[Carl-NC]

That should be fine.

How with a DD coil - but amplitude on Rx is verry low

[Fred]

The coil that is on the magum diagram work fine too.
For a DD you should find the right inductance so frequency is OK.

Hi Fred
Have you done a DD for magnum

regards

[Fred]

Hi,
Yes i did, but it was too complicated to use and then i built the tesoro golden sabre, much simpler and excellent results.
I have used the coil from magnum to the TGS,work OK.I will post later more results about coil for TGS.
Regards,
Fred.

yesterday I made a DD for magnum it works better from magnum's coil
but have a problem with indikator it is verry slowly

[Fred]

Forgot to say, i have posted infor about DD results on the TGS thread.
For your "indicator" i think to remember there was a capacitor for speed response.

Thx fred maybe I must to add a other Oper Amplifier for the indikator I thnik - Amlitude is small

Hi,

I will build experimental eliptical DD coil for Magnum (10x14") but I don't know how (about winding Rx coil - turns number, wire diameter and tuning). Can You help me?

for 26cm DD coils Tx is 70-72 turns diam=0.5-0.6mm2, Rx 150 turns diam=0.2-0.3mm2

.....

DD coil for MAGNUM : D=27 , Tx 20cm,61n,0.28mm - Rx 20cm,61n,0.28mm
100% correctly.
