How much juice does it use?

I've used a Grinel TR16 in my P106

Forum 2

A board with two holes drilled for head rest. It runs of mains or 24V, so I used a 2nd 12V car battery in the boot.

About 200W SSB.

Top of hill 1500m and long wire to a fence post.

Another time I used FT101ZD from same location, mounted over passenger seat same way, but with a generator beside the car as I don't have the DC adaptor.

That's a pic of a Mk II, like I had then.

I now have a very late model MkIII, but its not been out yet.

The Grinel TR16 is rare outside South Africa. Early solid state rig with late 1970s RCA CDP1802 cpu for secure frequency hopping (Did they pay Hedy Lamarr?). One of the first solid state CPU controlled secure spread spectrum sets.

Grinel was SA Racal before Sanctions. Also called Milcom.

The FT101ZD is hybrid with 3 valves for TX, a 12BY7 driver and 2 x 6164 in parallel pure Class A rather than push pull. Class AB would maybe give x4 power...

I've used my Grinel version of Racal Syncal 30 successfully with a big CB whip. Tunes from 160m to 10m with the internal tuner.

Not my exact model, but very similar.

I gave the Grinel TR16 back to my friend with the local secret Radio museum as it ONLY does 100W to 200W, no use for data modes. Very scary aggressive ALC on it. I must persuade him to let me do a virtual online version as he isn't open to visitors.

I replaced the PA transistors on the Racal syncal30 and now it's not stable below 14MHz. Too much gain.

The FT101ZD is working OK. So maybe 80m at suitable time when conditions are ripe.

Before I broke the previous PA on the syncal I did manage to work the Orkneys one evening on 160m with a 4' fibreglass whip while sitting on settee in living room. Good conditions I guess.

I have a portable bi-cubic  ex military aerial that is like a guyed tent pole 12' tall with x4 military whips that screw in. It works without tuning from 40m to 4m. It's nice with the FT187ND (the only new radio I bought EVER in 40 years) and very nice with the 80W battery powered PA I made out of filter board of someone's scrape Alinco  and so called "CB PA" from Italy. I had to change the two ferrite binoculars to get it to work below 21MHz. It's OK 160m to 10m with manual band knob or auto switching using a bargraph IC and the the FT817 analogue band signal on AUx connector.
