Illustration from our river configuration card: on the front panel you can see the marking "ERMAK R-660". The exact designation of the proposed block is checked by nameplate and documents.

Request price and kit GM-660: river configuration

The name GM-660 appears in various radio post descriptions. For river communication, the buyer needs a specific proposed set that corresponds to his network and documents. Therefore, the order begins with the configuration identification. Comparisons of just the Motorola name or the seemingly familiar front panel leave too many questions.

What you can see in our card and in the photo

Our card describes the GM-660 river position, and its catalogue illustration reads "ERMAC R-660". This information must be verified for the proposed copy. Send the designation of the installed device and request a photo of the nameplate of the supplied unit. Illustration helps to know the shape of the product, but does not confirm the configuration and documents of a specific delivery.

The warehouse list also indicates the river destination GM660. The number and composition given in the original file are related to this list; the current quotation is confirmed separately. It is impossible to automatically transfer to the river position the characteristics of a conventional land station with a similar name.

Replacement of the old river post

To replace, attach photos of the old station, power supply, antenna connection and mounting. List what is planned to be preserved. Compatibility is confirmed for each element: an externally identical connector or bracket does not mean that the belonging is suitable for a new configuration.

Separately describe the working channels and correspondents. If the usual control scheme is important, specify the actions of the operator: channel selection, sound adjustment, microphone use. This helps to compare replacement options by day-to-day work rather than by the face panel photo.

How to compare quotations of different stations

Comparison of the river set GM-660 with another device is carried out on the same task: network, accessories, accommodation, documents and work. Ask for a table of saved and replaced items. A lower price of the main unit does not always mean a lower cost of the finished work post.

Below the main product is the first. Ermak SR-360 and the source DM-R2-24 allow us to discuss related positions separately. NVR-3000 is listed as another product in the catalogue; belonging to the same radio group does not confirm the interchangeability of bands or the possibility of operating on your river network.

What to fix before payment

Save the quotation with full designation, completeness, condition of equipment, confirmed accessories and a list of documents. The order of setting and acceptance will be agreed by responsible specialists. If part of the information is still missing, it is better to mark it with a separate question before the order, than to find out the configuration when receiving.

Price and delivery of river kit

To buy GM-660 in Moscow, Novosibirsk, Omsk, Samara, Nizhny Novgorod or Astrakhan, send the assignment of the post and the city of receipt. For Almaty, Astana, Aktau and Atyrau add the country and details. The actual availability, price and term will be confirmed after the configuration is verified.
