Digital MPX Forum

Hello to everyone! The progress so far, is:

• Re-designed to fit into 1U chassis
• Replaced buttons with rotary encoder
• Added extra features in UI menu
• Fixed some software bugs
• Added extra functions (DC blocker, etc)
• Output RF power is 30W (80W unit, s/w locked)

The last photo is from a mountain installation, operating since September.

Next steps for the next model are:

• Upgrade to a larger DSP chip
• Internal RDS encoder
• SFN support (D-SFN for D-MPX)
• On board Ethernet

I decided to keep this model as a "low-end", and provide the next in 2011.
My promise to some guys here will be fulfilled soon, but currently I need local feedback to correct fast any mistakes found…

Hi Sigmacom, great to hear from you again.
I was beginning to think that this project had disappeared, I’m, very glad it’s still happening.
Also very much looking forward to trying out working model, hopefully not long to go now 😀 .

My preciuuuuuuuuuuuusssssssssssss 🙂)))

yes it works! and it works not just good.
it is the cleanest MPX signal on the PLANET ,

[feeling]

Nice!

@Sigmacom: What will be the estimated price to pay for this baby when it ready? I wish to buy 2 or 3.

[sigmacom]

It’s not ready to be announced yet, but it will be A LOT cheaper than any equivalent DDS exciter.
In fact, it will be much cheaper than some good analog exciters, like RVR PTX-30LCD/S+AES/EBU option (catalog price).

No.. No.. Sigmacom said it will be cheaper than RVR PTX-30LCD/S+AES/EBU, which is something like 3.500€ ..

Resurecting this old thread again…

Any news on the exciter/prototypes.. Sigmacom??

Yorkie.

[Dj Buik]

This one ?

Actually there are no more exciters left (except one I kept for myself).
The first production was quite small, and prototypes went to local stations.
I liked that, because I could have them back for modifications and return them fast and easy.
That’s why I decided not to send any prototype outside my city – at this phase

Prototypes are operating on mountains since September 2010, and I had feedback and suggestions, like as:

– Internal RDS (although many radio automation systems do not support UECP)
– SFN support in basic configuration (audio buffer for delay sync, GPS clock)
– Separate connector for A-MPX (currently used analog Left channel connector)
– Ability to reduce RF power by time schedule (e.g. lower power in night hours)

Lack of time, is my root problem… 😳

[yorkie98]

Wow, just glad to see it’s still moving forward. I Would still very much like to road test one of these and will be able to do so on a large city licenced station in the UK. Please keep us posted…

Yorkie.
