Yes the IC-208H dual bander does have an intermod issue.I have learnt to tolerate it by adjusting the attenuator.The intermod is very prevalent especially when i am scanning the trunking region from 415mhz to 418mhz.Have experienced it on other sections of the spectrum but it is not quite so severe.
Have not heard any intermod noises on the 476.175 TO 477.400 mhz section.The transceiver has been modded for uhf citizens transmit.Most functions can be adjusted via the front control face or on the microphone.Some of the features are intuitive.For convenience and practicality my preference is the microphone adjustment.
Because the IC-208 has so much functionality it is prudent to read the instruction manual thoroughly.Being able to set up almost every function from the microphone is a total joy.All buttons on mike are backlit.When you transmit there will be a red light.Upon enabling a function there will be an orange light that indicates you are on an operational status.
My transmit power levels are about 10Watts for low rf.25 Watts for low2 rf and 50Watts for high rf.I only use high rf for long distance and even then the modulation is kept to the barest minimum.Nothing is gained by continuosly subjecting a radio to excessive heat.I trust my radio technicians advice when he mentions" Heat stress will eventually destroy the radio components so henceforth it's lifespan will be shortened"
Even on low and low2 rf settings i keep my transmit periods reasonably brief.I use the low1 when anywhere elevated for example the mountain ranges.If i have trouble accessing someone out on the city plains it is set on low2 rf.The most temperature i will allow on heat sink is either tepid,or in between tepid and warm.My limit is warm.Have not remoted the 208H and are using it in one piece.
The warm level is checked by doing the palm or back of hand test.In my former sedan i managed a few long distance contacts but nothing too sensational.Recently traded in the car for an SUV Offroader type vehicle.Currently using a "SCATX" bandspanner antenna on a elevated feed.This elevated feed has been mounted onto a heavy duty nudge bar.Some people choose 'TJM' or 'ARB' bull bars.
My preference was "ECB" East coast bull bars who are a queensland firm.The nudge bar is heavy duty as in it has a nice solid diameter.Unfortunately the radio speaker is on underside of chassis.I velcro mount the 208H on top of dashboard mat.Henceforth for ease of audio receive an external GME electrophone speaker has been connected.Quite happy with the GME received audio quality.
Ideally i would prefer a "Codan" external speaker.Silly me got excited upon trading in my car.Forgot to remove my good old Codan speaker from the previous car.The GME speaker is acceptable but the Codan just seemed to have that nice hint of depth and base to it.Because of work duties have not experimented as in long distance modulation with the IC208 in my SUV offroader car.
Direct entry for receive and transmit frequencies are done immediately via the microphone.The RF power levels can be enabled also from the mike.Transmit power levels are indicated on radio display.The signal meter level is easy to focus on and will be clearly defined on the IC-208 screen.
The scanning speed of channels or frequencies is very quick.Alphanumeric text can be edited for your channels in the clone software.Also this text edit can be entered via the HM133 microphone.I just love the one touch PTT automatic transmit function.Basically you can modulate hands free and have no thumb on the PTT button of mike.
Another convenient feature is the Ctcss tone decoder.This is activated from the radio face or from the microphone.The IC-208H has two separate set mode areas independent of each other.There is a "SET MODE" and an "INITIAL SET MODE".In these modes you can select parameters and adjust them.
Be careful with the "Partial reset" and "All reset" functions.Obviously the critical function would be the "All Reset" procedure.Resetting the transceiver CLEARS all memory information.I have a habit of performing different button sequences to see if any extra modes appear on my Icom's.
HELP! So this is what happens when you get excited over a new toy.?????.I powered off and powered on again.Oh my goodness! Where have all the memory channels dissaapeared to.All the scan banks were totally deleted.Fortunately the good old long distance IC-F2010 commercial beast was at hand. UMMM! AHHH! Excuse me mate but i have a problem.Would it be possible for you to re-clone my IC-208?
Oh allright! Bring it over and dont forget your 0PC 478 clone lead.You Wally! Remember how i warned you about the reset procedure.
