Following on from this evening's excellent presentation by Den, I thought I'd have a look at the latest RSGB EMF calculator (version 11), which can be downloaded from here: https://rsgb.org/main/techn

Hi Dom. Though I haven't done the calc run, I can confirm that there is AS YET no PAC for the 20m dipole/inv V. I will have a look when I wake up properly.... nodded off watching a film till my phone

Thanks Den, I was just trying to get ahead of the game by checking my HF antennas. I'm fine with my current 2m/70cm Colinear setup, mainly due to my Diamond V2000 antenna being 5.5m up on a scaffold p

Noted the V2000 anomaly at 50megs. I will add it the list of issues noted. You are absolutely right, the V2000 should do 6 (and 10 ?). I think the achilles heel of the whole calc situation is going to

At a suitable point, I will again email John and update him with Members'discoveries. However since the Pre November deadline is 110 Megs and up, I think he would appreciate resolving any final final

Dom, I have just done a run on the IcnirpCalc and attach results page for 6M for the V2000. I have assumed some pretty 'standard' condx with 15m of RG213 and an ant height of 5m Mode FM and 50% TX:RX

Thanks Mike. Would be nice if there were a "subscribe" option so we got push messages! I haven't come across such an option. You? Den

New version 11b now out that seems to have fixed some of the printing problems

#EMF

Thanks Den for taking the time to delve a little deeper. If I get a chance over the weekend, I take a look at the finer workings of the spreadsheet to see what data is being pulled from where, etc. It
