looking at the features and general appearance of the jcd it looks like another adonis clone,
adonis mics are found with several different names on them, a friend told me they are all badge engineered by nissie,
i have owned almost all the different models over the years including the eq version same as the mfj in the link and the old eq version,
they all use electronic ptt not a regular switch, some have two or three cables so you can have more than one radio hooked up and switch between them,
the higher end models have timeout timers that beep after about 2.5 minutes to remind you the radio is keyed,
when the batteries are getting low the mic will unkey the radio when the TOT activates,
the adonis compressor works ok for an audio based device, more punch than the flacid pumpy sound of the kenwood mc85 but you cannot turn the compression off completely which would be a bonus,
my favourites are the none compressor versions. imho and most other peoples opinion they sound better for less money,
next up would be the compressor mics and least favourite would be the eq with compressor versions, you can fiddle with the eq all day and not get the sound you like, not enough bands on the eq,
imho the
fm tone setting is a bit bass heavy on many radios for my ears but not woolley, the
ssb setting switches in a smaller value series capacitor to remove bass making it thin sounding, both can be altered with a couple of capacitor changes,
the eq mics EAT batteries if you dont power them from the radio,
for local ragchewing or dx in the clear the adonis/clone mics are one of the better and most pupular base mics available at sensible cost in the uk,
for busting pileups/noisy difficult conditions they are no match for a decent rf speech processor.
in onair tests at distance my old datong automatic rf speech processor set at a low 6db compression is perfectly readable when the adonis mics on any setting are difficult or impossible to understand,
only you know what you want from a mic.
