Mode Zero

Hi guys this is my latest acquisition. I suspect of Macgregor origin.

I’d love to know the true identity and the circuit diagrams for each of these if anyone has them ?
As you can see I have some missing components on the TX board.

The TX says Carrier wave and tone transmitter on the back of the PCB. The RX says CW receiver Mk2

I suspect the TX is a MK2 as well with the switches mounted through the board.

I would love to get these operational either flying or floating. Any help much appreciated!

Ok so now I’m thinking the transmitter can be assembled as either Tone or CW hence missing components and alternate tag positions. Maybe someone has the assembly instructions?

Perhaps an ED ...??

Some valve circuits here also.....

They are MacGregor kit build units. I believe I may have the circuit diags . I'll have a look for you.

Shaun that’s really kind thank you
Yes I’m convinced they are Macgregor
I’m guessing these may be the last Valve versions before the transistor or hybrid versions

I've sent the pdf scans to Phil who will be putting them in the archive section of www.singlechannel.co.uk

Cheers,

Shaun

I am pretty certain they're the MacGregor Aeromodeller Ivy MK2 Tx and Rx kits, the last commercial Tx and Rx that used valves. If Shaun can't find the instructions, I know he let me have a copy a while back, but I can't find them at the moment.

Sorted Mike,

I've unearthed the boxed, unbuilt MacG kits in my collection.. scanned the instructions..
