Title: Another QIX transmitter hits the airwaves...
Post by: GW0FZY on February 24, 2018, 03:50:47 PM
Eventually sorted out all my minor problems with the build and had my first QSO with my new TX on 3.615 Mhz with excellent audio reports. Just ticking over with 100 w carrier. Thought I would share a few pics. Thanks to Steve for doing all the hard work and making all this available.

Thanks Vic! The meters are called Trumeters and they are available quite easily although they are a bit pricey. If you search on youtube there’s a chap in the US who has also used them for a Class E rig.

Beautiful job!  Nice!!

I'll listen in on some of the SDRs over in your part of the world if I know when you're often on.  Would like to hear the rig operating - that would be neat  :)

Steve,

Most of the AM activity in the UK on 80 is on 3.615 Mhz. We have a net on Saturday mornings ( The VMARS net, Vintage Military Amateur Radio Society) which starts at about 0730 GMT and runs to about 10.30 so I will be on this coming weekend with the new rig. Best local SDR's are Hackgreen or G4FPH ( aka the Fabulous 160m SDR) so if you're up would be good to hear the rig and let us know what you think.

Looking Good! The high visibility and programmable alarm set points/alert colors made the meter worth every penny to me.

Well done Brian! Yes your video was what persuaded me to splash out on the Trumeters ( they should give you a commission!!) . I battled to get 10 amp shunts on mine so in the end got a couple from China. Problem I had was trying to program them with shunt to get a linear and accurate display; I don't know if you had the same problem? One of my ammeters still reads a little higher than other. Overall, they do make the rig look the part.

Hi Justin

Thanks!A commission would be nice. I ended up using the shunts that came off the analog meters that I replaced. I noticed that these meters are VERY sensitive, weak connections or even different lengths of hook up wire will change the meter readings and make things hard to calibrate.

A very cool meter, and as far as I know Justin , you and I are the only two e rigs using the trumeter meters.
