DDS VFO

[Smokinone]

Just saw a video of this modification or add on. Not sure if this should go in the CB and Export and accessories, or here.



A link to the video on this VFO for all CB radios it looks like.

Looks like a pretty nice add-on for sure. I bought a Circuit Domain board early on, but never got around to putting it in. This DDS VFO looks to be able to run circles around the DigiMax Lite.

This also will stabilize the Galaxy 959, and probably the Texas Ranger radios like the 696Freedom, that have the drift issues.

Looking through the instruction sheet, if you get the kit, you will still need more components that are not supplied in the kit for the install.

By the way, I'm not advertising or endorsing this, and I've never heard of Troy's till I was sent the video from a friend.

I was looking around and see this may have been out for a few years. I did a search here and wasn't able to locate it.

Not sure if this kind of posting is allowed, so if it's not, would the moderators delete it.

I confess, I haven't read all the rules.

Wait, there's rules?

Troys radio service is completely legit and are the real deal - they are a Flex radio service repair center in addition to their business service contracts and also CB radio

Don't know what the guy is charging for this mod but the encoder seem abit flimsy

He is reselling the kits from a guy in Brasil.

Everyone uses the cheapest chinesium encoders it seems.

yes, they are wobbly and flimsy and suck.

the cure is to use a genuine ALPS encoder, and they can be 10-20 dollars a piece, when you can find them.

whenever i do a radio that uses an encoder for a channel mod, i always change the encoder to an ALPS.

there is actually a spec for how much effort it takes to turn them, and the ALPS feels much more like a channel selector while still allowing you to spin it fast if you want.

im curious as to how much receiver noise is created by this kit.

Hasn't been an obvious problem in the ones we have installed so far. I was skeptical about the Si5351 chip, but so far so good.

What I really want to figure out how to do is use all three outputs from that chip to replace all 3 oscillators in the Tram D201A, not just the channel LO.

Anyone hav instructions on how to install this in a 29 or 78xl bought one from try no info on there help files for this radio

 

[nomadradio]

Good question. You would have to program it to jump frequency 455 kHz when the mike is keyed. That's what the factory PLL chip does.

Should be preprogramed from troy was my understanding It's a kit first you put the whole board together I guess the info is there for that but not install on hardly any radios. https://www.ddsvfo.com/files

 

[Cam Tetzlaff]

Does anyone have any new information or experience with installing one of these?

$99 for a bag of parts. Toby, TroyRadio and POC for Brazilian originator, is so confident in the product they quit assembly of them. Stating too much walk-in load work. He did mention goobermint contracts; and, I thought of chest pounding.

#1 Delving into political debate is hot, soft, and stinks; like Osama bin POTUS. And off-limits.

These images acquired during my investigation into worth of swapping out the existing Frequency Switch Mod for the DDS-VFO mod. I don't have the skills nor eyesight to do it myself. The initial outlay of $99 for a bag of parts required a suitable technician do the mod; plus the pending Ruby Anniversary recap and refurb. I was looking at a costly antique.
