Hello,

I am looking for some insight from the experts out there on vintage radios. 
I recently picked up a vintage Black Porsche (58000) model that has a receiver and servos already installed.  As they seem to be period correct, I was hoping to find a TX that would be compatible with the installed RX (shown in the attached picture).

I don't know much about SANWA equipment so I was hoping someone could tell me what TX would match up with the receiver I have and what the two tags on the RX mean.
One says "BAND 6 27.245 MHZ" and there is an orange sticker that says "2F SRC-2118RS".  I am aware the 27.245 MHZ is the frequency but does the BAND 6 or the 2F have anything to do with identifying the TX that would have been paired with this RX?

Any help will be much appreciated.
Thank you!

I think the "correct" tx for that is a Sanwa "Mini Propo", one with the same fixed frequency as your RX - 27.245 MHz, band 6 (which is not the same as others band 6 - for example Acoms band 6 (blue) is 27.255.) Getting the early black TX at all will be a bit of a task (or at least expensive), let alone one in the right frequency. 

I have a similar fixed frequency Sanwa Tx moulded in orange, that was pretty cheap at the time so alternatives do come up & IIRC I think it would be possible to to unsolder the crystal and either put in a lead to make the crystal swappable, or solder in a different crystal. 

Other options are to use a later Sanwa "Beat" or "Dash" TX, but if you're going to do that, you might as well use a matching period Rx with swappable crystals.

These fixed frequency radios are interesting, US law at the time was you were not allowed to change transmitter frequencies yourself, I'm not sure when that changed, but that was still the case when the Acoms mk.i and iirc the mk.ii sets - with their swappable tx crystals - were available. 

Fixed frequency radios are more associated with toy grade RC, but even so there are levels within that, for instance Atcomis output ranged from very, very basic one button wired remotes, to their "Super Alpha" transmitter, which was basically identical to the Acoms mk.i TX but with a soldered in crystal, and was paired with high end RC cars not far off hobby grade (and price). 

 

No such thing as a Sanwa "Beat" TX I must have been thinking of a JR "Beat" or JR "Jeep" TX


Example "Mini Propo" from 1975 and on, live listing on ebay (# 235732658400):




My orange (band 1, 26.995mhz) TX, no model no. but I assume a bit later than the above due to lack of graduation markings on the sticks and single light - note size next to standard CD jewel case (the sticks are still uncomfortaly long for me), it takes 6x AA batteries.





Example GC2200 TX (ebay 315741948584), not "correct" but not horrendously so, xtal is hidden on the back:  




Getting a little too late, but the xtal is still on the back - Dash 1 (ebay 236395003257):

Yes the beat is a jr propo graupner. I had/ have some dash not 1 only dash with square black tx (v2 with inverter swithes and black connectors) and older without switches and white connectors. 2 with big rx and removable crystals. I sold them a little time ago.  My first lunchy had a v2 and still working. My v1 has been mounted on my pajero dakar.

Jonny,
You were correct on the TX for the receiver I had. 
I was skeptical that I would ever find one but one came up in Japan on Buyee in the same frequency and band 6.  I couldn't believe it.

Thanks for your help on this!
