CPCRadio module

Do you have audio connected to pin 1 of the expansion port so that you can listen to the radio in the CPC speaker?

[p135]

At the moment audio output is only through the 3.5mm jack, I guess this is something I can add in a future revision of the board maybe with an extra jumper to enable or disable it, of course output through the speaker would be in mono.

I'm not sure if it's as easy as adding a connection between the output of the radio chip and pin 1 of the expansion port, I think a few components are required to mix the external signal with the audio coming from the CPC but it's definitely doable, I'll have a look at the schematics later

I think a few components are required

I think one resistor.

I think one resistor.

I'll do a quick test just to be sure but that would be a pretty easy mod even for existing boards, one could just solder one side of the resistor to pin 1 which is pretty easy to spot and then a wire from the resistor to the left or right channel pin of the 3.5mm jack

Hello! Good to see you here! 

Allow me two questions: Could you tell us which I/O addresses you use for the Radio module? 
(So I can see, if there is any collision with other hardware.)

And how much would be one Radio Module with MX4 adapter and shipping to Europe (Germany in this case)?

[p135]

The address range is $FF00 to $FFFF

Tracked shipping to most EU countries is 12€, I usually put these modules in a small package instead of an envelope so I can package them well with some extra bubble wrap

Price for the new boards with the MX4 compatible connector is still 50€, you mentioned an adapter but I actually made a few changes to the layout of the PCB so no adapter is required. I can either solder a 50 pin edge connector or the 50 pin male header that fits into an MX4 female slot. Since I'm only making a few of these they're all hand assembled.

Of course if you want the MX4 version I will send you one with the right connector

Do I have to open a different thread in the Classifieds section?
