Topband: FT-1000MP

[Kip Edwards]

Hi Frank,

 

               Thank you very much for your detailed reply.  As I  noted, I don’t have a FT 1000MP but I will pass along your email to Andy and I know he will very much appreciate hearing from someone like yourself.  As I said once at a Contest University session, I’ll stay and listen to Frank as long as he’s willing to talk.

Hi Kip,

 

Your question involves perhaps the most frequently misunderstood

aspect of FT-1000MP receiver operation, a result of the poorly

written description of  Menu 8-4 on page 91 of the operating

manual.  A much better description and illustration of  pre-amplifier

selection menu 8-4 and the IPO front panel push button appears

on page 30 of the operating manual.   

 

Two controls must be properly set to optimize FT-1000MP receiver

front-end performance on 160, 80 and 40 meters: Attenuator and

IPO.  When IPO is enabled, it bypasses the pre-amplifier selected

by Menu 8-4.

 

The FT-1000MP has three pre-amplifiers:

  - a 1.8 - 7 MHz pre-amplifier  (IPO should be enabled when

operating on 160, 80 and 40 meters to bypass this pre-amplifier)

  - a pre-amplifier with excellent sensitivity on 24 and 28 MHz

  - a wideband (FLAT) pre-amplifier with very poor 28 MHz sensitivity

 

The front panel IPO pushbutton bypasses the pre-amplifiers entirely,

feeding the antenna directly into the first mixer.  I always enable

IPO when operating on 160, 80 and 40 meters.

 

The Attenuator should be set to the highest setting while providing

acceptable receiver sensitivity.  I almost always set the attenuator

to 18 dB when operating on 160 meters.

 

I always set Menu 8-4 to TUNED, allowing the FT-1000MP to

automatically select the proper pre-amplifier for 12 and 10 meters,

I never use the 1,8-7 MHz preamplifier because I always enable

IPO when operating on those bands and I never set Menu 8-4 to FLAT.

All,

 

               I have been corresponding via email with Andy, SP6AEG,
regarding the 5J0P DXpedition and other topics.  This morning I received the
following question from Andy:

 

"I received from Janusz SP6IXF as  gift transceiver FT1000MP with a set of
filters in optional (2 kHz / 250 Hz) ssb / cw + roofing filter.  I have a
dilemma, do not know who Receiver Front-End RF Amplifier should be active
for optimal performance for 160 m.  I have a choice of flat or Tuned for low
band.  Do you have on this subject some knowledge?"

 

               Is there anyone on this reflector who can offer any help?  I
know nothing about the

FT 1000MP (among many other things) but I'd like to help Andy.

 

               Many thanks.

 

               73 Kip W6SZN
