feel like doing it yourself I strongly advice you to contact an electronic service shop to do it
for you. Be careful ! Buying a new HM-151 is expensive!
Mic gain at 80 - 100 % , COMP on level 1 only.
Try these setting for transmitter bandwidth (TBW):
W(L) 100
W(H) 2900
W= Ragchew
M(L) 200
M(H) 2900
M= DX
N(L) 300
N(H) 2700
N= DX (sounds almost like Heil HC-4)
This way you will have good settings for both Ragchew and DX. Only use COMP if necessary
Note !
If your IC-7000 has been modified internally (microphone preamp.) you will probably not
notice any difference with this modification. This is the case with most IC-7000 radios sold
in Scandinavia. They sound good in SSB-mode, but a little low on bass in FM-mode. There is
no need to modify these radios any further (leave them as they are). If you on the other
hand are planning on buying a new IC-7000, ask for an unmodified radio (microphone
preamp.) but let the dealer replace the C30 capacitor inside the HM-151 for you.
Good luck !
