Tried to toner transfer but that was giving me a hard time so I went and tried another free software. Still need to learn the whole 3d modeling though. Hope the hole gets drilled out correctly.

I’m interested in details of this mod. I know majority of the newer rigs run the AM audio through a DSP and a balanced Modulator. Icom rigs I have both suffer from low modulation .

Using my Lincoln for my template , gonna roll my own for a few HG 454’s I got

Light scrubbing of the schematic tells me they used the same layout as the Lincoln II. Being that I have a Lincoln II I widen the receive and swapped the 2nd IF and it sounds decent and close to my modded 2950 in terms of audio quality. Sensitivity is nowhere near the 2510/Lincoln

I bought and used HG 2879, MRF454, 2312 and 1969. All were the same or better then originals.

Hg2sc1969 is like under $5 each. Mosfet are easy, voltage divider to the gate , just gotta bias the gate on .

HG2SC1969 are available

yep

Common problem for older 2950, can’t recall the cap but it’s a value change in the pF range

VCO area

Modulation transformer radios like the 29, pump out up to 35-40 volts peak to peak to the final. My take on the mosfet mod is to “volt” the final and prop up a voltage divider to the gate to drop 3.5 volts from a 8v TX source. Treat the final as a PA stage rather then a modulated stage, maybe...

the pic is a schematic section of the Galaxy 44 or any other radio that uses a 4558 for a mic preamp. pin 3 is the audio input and pin 1 is the output. Pin 1 and 2 form the feedback section. The Top Gun CP1 removes the R165 gain resistor and inserts the CP1 two wires. Between the two wires are...

Not sure why the Top Gun gets the bad reviews . I like them and always try to do my research before buying. Lately while browsing through schematics, I seen something cool. The K40 had a good mic circuit and sounded pretty good also. The schematic shows an opamp with a diode combo, resistor and...

I’ve seen as low as $75 at hamfest to $150 on some ham sites

My alternative to the LED ring , you need the daughter board for the LED , usually 8 for $6 on the Bay. LED options galore, easily swapped when you get bored of that color http://smallbear-electronics.mybigcommerce.com/alpha-clear-shaft-pots-w-bushing/...

Yes, works good

Radios supply, 12v-14.5 , whatever you dial it up to is your radios ceiling(headroom). 2 watt carrier, 10 or so watts of headroom. 5 watt carrier , 7 watts of headroom. With a ceiling of 24-30 volts connected to the supply side of a Darlington, you now have tons of headroom to grow from with...

Nah bro, Jose uses a buck converter for the dual supplies and the 24 volts from the radios supply. MMM now uses a buck converter to boost the radio supply up to 30v for his single supply second version. All Asymod has done so far is add some lights and some audio tailoring crap like EQ and a...

Bro , Motormouth Maul has tons of Gates, also a bunch of clips of Mauldulator builds on YouTube . Asymod is a copy of Motormouth Mauls first Mauldulator board. Stand alone Asymod cases are 3D printed, feels pretty cheap
