DOMINION OF NEW ZEALAND
POST AND TELEGRAPH DEPARTMENT
4th June, 1927

Dear Sir,

I note that you are using a one valve detector unit of the N.Z.R. type of radio receiver, and desire to bring to your notice that under certain conditions of operation, this receiving set is capable of unduly energising the antenna system, and of causing interference to other broadcast listeners in your neighbourhood.
In order to obviate this infringement of the regulations, the filament current, plate potential, and value of the reaction coil must be reduced to minimum requirements at all times.
The addition of a stage of neutralised radio frequency amplification, if correctly installed, would eliminate the possibility of causing interference by radiation, and is, this reason, strongly recommended.

Yours faithfully,

[Handwritten signature]

District Radio Inspector
