Latest Version 5 HRD (Ham Radio Deluxe) Download

I used to host the last free version of HRD version 5.XXX however I had a (VERY) polite note from Dr Michael Carper (WA9PIE) explaining that the version I was hosting here, was actually compiled by the new HRD team, after they purchased /acquired the rights from Simon Brown.

Michael was at pains to explain that he wasn’t being heavy handed, he just wanted me to know that technically, I was giving away *his* product.

Silly me!

That download has now been removed – but I’d like to take this opportunity to congratulate Michael on his tone, friendliness and professionalism. In this modern fast-paced world, it’s becoming a rare trait.


 

But WAIT! The latest version of HRD is actually better and has amazing support too. Version 6 is awesome and has a number of enhancements including a wider selection of rigs, FSK keying etc etc.

Suggest you check the HRD guys out here – and there’s a 30 day free trial!

 

ACOM 600s automatic HF linear amplifier

James (M0YOM) and I are pretty excited about a new automatic, solid state linear amplifier from the ACOM stable. 160m through 6m with continuous duty rated at 600 watts. Well, when I say portable, I mean it’s more portable than say the ACOM 2000 – but still heavier than say an AL811. But hey, it’s super sexy, automatic and has that amazing legendary ACOM metering and inbuilt protection.

Multi-banding 10m long 1/4 wave 40m vertical antenna for 15m band

I’m always curious to discover if a mono-band antenna will work efficiently (or otherwise) on another band. I recall that when I first studied antennas, it was explained that a dipole antenna will be resonant on every third harmonic. That means a dipole for 7.1 MHz should also work on the frequency three times bigger, in other words 21.3 Mhz. Actually, experience tells me that the real resonant frequency will be a little higher.

58 -vs- 14

1/4 wave vertical for 40m band can also be a 5/8th for 15m band
