Hello AllanI assume the 10A mod is a matter of increasing the series R with the meter to around 800k? I suppose a 3way switch and extra trim pot could be added to preserve the 1A range too. Thanks for the note re-shipping Monday. Look forward to getting the Kit. 73 Ian G4GIR-----Original Message----- From: Alan Melia Sent: Friday, August 4, 2017 9:36 PM To: [email protected] ; [email protected] Subject: LF: RE:G4HUP aerial current meter It has just occured to me that the 1A range may not be high enough for some of the LF QRO merchants. There is a simple mod which will extend the range up to 10A though you should be aware the ferrite core has not been tested at this level of RF. These cores are used on mains leads carrying up to 13A so I think they will be OK. Thank you to those showing interest, there are a few kits still available. Alan G3NYK |
