I always thought the main veronica 1W board was a PLL, competing with the NRG.
So they made a free running VCO only one ? Interesting.
Their current PLL 1W is the tiny components one
https://www.aareff.com/en/1w-pll-fm-transmitter-kit/Given the price I would definitely got for a PCS over that. 100pct, personally. Aaref is £261.00 inc vat + shipping for 1W stereo

pricey.
Albert does not seem to like Aareff for some reason, I don't know enough about PLL rigs to be able
to confirm or deny if they are any good. Albert seemed to know the man who made NRG and spoke highly of him.
I wish the PLL makers would very clearly state if these devices are stereo out of the box as the PCB stands before adding extras. It is always a bit encoded pardon the pun
with MPX and what not. But they do not say if they already have stereo TX capability. It should be clearer. That would help them compete
against the Chinese 0.5/1/5/15W chip sprog rigs.
Ok you need to buy an encoder for Aareff that explains it is mono out of the box. All too expensive and there will be import charges
and courier charges on top. It seems they are in Spain ? You would be looking at £300.00 + by the time it gets to you for 1w.
