Hy-Gain V (2795DX); Restoration

Ok... I picked this Hy-Gain V up the other week. It's a bit on the rough side. so I'm going for a full restoration.

Posted Image

The front panel bezel has been horribly painted with a garish, overly metallic and cheap looking paint... complete with overspray into the black areas.

Posted Image

The case is a disaster. Why do people not prep surfaces before spraying???

Posted Image

...not that it would have helped, as it's a million miles away from the factory finish, so this will be blasted back to bare steel and started again.

The front panel will be sanded down to bare plastic, and the front panel also... yes... I mean sanding off the satin black and lettering!

So what am I going to do to get it back?

I'm having a white water slide decal made, based on accurate artwork I've just created...

[imgw=500]http://i.imgur.com/in7MCPi.jpg[/imgw]
(image size edited by admin)

The black left hand panel, once surface prepped, will be sprayed in satin black, then the decals applied, and a very thick layer of non-shrink varnish applied. Once cured, it will be flattened back with 2400 wet and dry, then a final satin lacquer spray applied.

The silver will be resprayed the correct colour once the surface are prepped.

Same treatment for knobs of course.

Inside is not in bad shape...

Posted Image

...just done a full alignment... all is well. Modified the final bias circuit to cure the typical cybernet scratchy audo. Done the "thimping" squelch mod.

It has a broken VCO core as they always do (why do the chimps always break these things?) so a new one from Spectrum is on order. The VCO is actually perfectly adjusted, but it's still getting a new one.

Bleep reconnected and removed from the NB switch, and NB re-attached.

I'll post up updates as and when they happen.

Fingers crossed.. yeah. The Hy-Gain V is a real memory lane radio for me. I have this one, and have just bagged a 4x50 band 8795 off Ebay too for 60 :)

Nice one David,
My mate always loved his Hy-Gain radio's, and I was always a Ham Int. kinda guy. But, in 2016 I think the Hy-Gain stuff looks so much more retro so good luck with your restoration !

I love them Nick. They get bad rep, as do a great deal of Cybernet rigs. I admit, they're not as good on TX as Uniden based stuff, but the PTBM121D4X board, set up well is a great receiver.. and if you can't hear them, you can't work them :)

The bad rep for TX is entirely justified, but easily rectified. A simple modification to the final bias(Changing two resistors) cleans up the scratchy audio on SSB completely to the point where it sounds as good as any other CB radio. The boxed in, quiet FM audio is also rectified with a simple resistor change. The VCO is a pile of crap, but Spectrum Communications make a replacement VCO for 7.50 that will also allow wide banding if desired. Basically... dealt with correctly, the PTBM121D4X is a fantastic board, as is the PTBM125A4X and PTBM131A4X, which depending on what model of High Gain V you have, it will have one of these three boards.

Info for readers and anyone researching (please feel free to correct and amend - all knowledge is good knowledge for these old radios:

2705 - 40ch only. RX Clarifier only *Labelled Hy-Gain V AFS on front panel. Very, very rare!!

2795 - 3x40 (26.515 to 27.855) no TX KC Shift - just RX clarifier. PTBM125A4X board

2795 - 2x40ch. As above, but 80ch.. also very rare. PTBM125A4X

2795DX - 3x40 (26.515 to 27.855) Separate KC shift and RX clarifier. PTBM125A4X board

8795. 2 versions. One was 5x40 (very rare), and one was 4x50 channels. As above regarding TX/RX clarifier, but has addition of CW mode, and switch-able bleep (labelled "ST.PEE" on the front panel). Boards were PTBM125A4X/PTBM131A4X depending on model. Does not have the "pee-wit" bleep, but the same single bleep as the Superstar 2K (Same board).

Maybe that will help someone.... somewhere :)

Doing some more work on the 2795DX.

After inspecting the paint, I've opted for stripping rather than blasting. Less aggressive.

Applying some evil, foul smelling paint striper to remove the 36 year old paint, and about 4 layers of other assorted cellulose spray paint other idiots have applied over the years.

Posted Image

20 minutes later.... a test scrape.. looking good.

Posted Image

A further 20 minutes and after a rinse... most of it gone.

Posted Image


It's having another soak to remove the last, stubborn bits and pieces and get as much bare metal showing before a final rinse and dry.

Back soon.

Just noticed an error in the post about versions further up.

Should read:



2795 - 3x40 (26.515 to 27.855) no TX KC Shift - just RX clarifier. PTBM121D4X board

2795 - 2x40ch. As above, but 80ch.. also very rare. PTBM121D4X board.

2795DX - 3x40 (26.515 to 27.855) Separate KC shift and RX clarifier. PTBM121D4X board

Top cover as stripped as it will get. Just needs a light sanding with 1200 grade wet and dry to flatten it ready for priming. Now I know the paint stripper works well, I'll do the bottom cover tomorrow.

The back panel was a complete mess.. red rusty and the black of the serial number rubbed off to silver. It was also severely dented where the rig had been dropped in it's ass at some point.

Anodised finish was gone for good.. so brushed steel and lacquered it is... until I can find a nice replacement.

Masked off for the first pass of silver paint.

Masking at this part is not that vital, it's when the black goes on things get critical!

The black parts will initially be sprayed GLOSS black. While this sounds awful, it will be the best surface for the water slide decal to be applied to. Once the decal is on, GENTLY... layer by later, a fine mist of matt varnish will be sprayed on. You have to be careful with water slide decals: Too much varnish in one go and they wrinkle when the varnish dries.

Not a massive amount of work done this weekend due to bad weather... awful for painting when there's damp in the air.

however... crap weather is great for keeping up your attention to detail. As I want this radio to look not only great... but NEW.... nothing escapes treatment.

The channel display filter was very, very scratched. I was worried it was beyond restoration, but I've managed to do it.

One of the popular myths you hear about scratches on plastic is that you can use T-Cut. You can NOT use T-Cut on soft plastics like this if you wish to retain pure, optical clarity (unless you follow it up with much lighter polishing compounds). T-Cut (the clue is in the name) is a cutting compound, and far to coarse to be used on plastics like this. If you use T-Cut, it may appear to be clear of scratches, but it will appear misty in appearance when light is shined through, and reflection from a point light-source will reveal many swirls and micro scratches.

You need a much kinder polish than T-Cut.

I use this with good results.

Here are the results: Literally as new.

I am really enjoying this thread, well done to you.

It is certainly a time consuming labour of love, but I doubt there will be many left in such good condition once you have done the hard work.

The make or break point is applying the decals actually, as to avoid a tell tale edge to them I'm going to apply the whole set of decals in one sheet... which is VERY difficult. Don't congratulate me just yet :)

I'm really hoping it goes well too, as finding as new versions of these is next to impossible now. Those that exist will be in glass cases somewhere, probably never to surface again.


I'm enjoying this. If there was enough demand for it, I could easily do this for a living LOL I find it relaxing.
