Although the topic is old, I still express my opinion. Moreover, in our country there are a lot of people with hands who can do a simple operation if they wish and make a marten (3, 4, 5) 10 times cheaper - taking into account new components.
And the thing is that inside the Marten 4 (I can’t say about 3 and 5, but judging by the characteristics they have one platform), the Vertex VX 160 radio station sits and no magic.
TTX martens and vertex:

Surprisingly, the original Vertex is lighter than the Marten 4.
There is a slight difference in frequencies - but it is easily "revealed" at the software level by reflashing.
Kunitsa incidentally cut the lower and upper frequencies from VHF 134 to UHF 512
Why a marten costs 10-15 times more expensive than its donor is a mystery to me.
