Hello- Welcom in IK2RZG " Max" & IK2QCF" Mary"'s QRZ page....

The first photo , Ticino river's valley view, in distance Alps with Rosa Mountain .

My name is Spartaco Massimo " IK2RZG" but friends call me " Max" .

We approched to this wonderfull hobby by chance.

The surprise have taken over on the great phisical phenomenon of electromagnetic waves!! ... And here we are after about 20 years !! ...

My wife's Marinella "IK2QCF" Mary" obtained the amator radio operator's patent in the August of 1990 ,

me after her the July 1991 .I falled twice on the CW 's exam sad.

We immediately started with digital modes " RTTY FSK " with FT101ZD & TS440 ,Commodore 64,and then also sotware WF1B,

modem CM400 I2ZGP ,Mosley CL33, 10/15/20 m, W3DZZ 40/80.

Then with Linear Amplifier TL922 we were competitive into lot contests ,"RTTY FSK" ...Roundup,WPX ,CQWW, ecc...

( 1° & 2° Antennas photo : tower mounted in the spring of 1990 and the dissambled in the summer 2008 .In our old Lainate's QTH.)

( 3° photo in August 2011 : Station's photo ,PSK31 "on the air" with new TS570 or old TS940S, Cat IF232C and SignalinkUSB ,SM220 TX IFtwo tone monitor)

( 4° image: This was our first QSL from old QTH Lainate)

From 2008 we live in Robecchetto con Induno a small town about 35 km west of Milan, placed in the " Park of Ticino"

For now we are using only 2 dipole : a Windom 10/160 m and a simple reversed V traps for 40 m.

The tower 9 m and Mosley CL33 sleep well in the garage... hi .. broken heart

Now our interest is always about the new digital modes ,in audio tones AFSK ..Software by Makoto Mori JE1HHT " engine MMTTY "

Seen: RCKtty & RCKlog by DL4RCK Walter Dallmeier ,QARtest by IKEQAR Paolo Toscano .Which we use in RTTY's contest.

The" Waterfall" of the software HRD + DM780 by Simon Brown HB9DRV in PSK ,HELL ,RTTY ,SSTV & and other digital modes .

Sometime we operate in SSB in HF....

 

Finally in summer 2012 .I assembled and then to go up on telescopic pole, antenna Delta loop10/15/20 meters

( can see you in the pictures below .. 5° & 6° images ).

I think it's very nice project Delta loop multiband ,simple and ideal for the DX contact.

Specification: Tipe 3 band 10/15/20 meters. Impedance:110/120 Ohm. and the choke 75Ohm 1/4 lambda =RG 11 = 50 Ohm.for any band .

The band 20 meters telescopic on support it's aluminium and15/ 10meters it's in fiberglass. power rating: 2 Kw....

( 7° image.. Last modified ..Spring  2015 )

 ..Telescopic pole basement diameter 10 cm and high 300 cm and full open on the ground up about 12 meter with  rotor chest  ...           ... Rotor Yaesu G-450C..... Working in progress ....yes....

8° images...  The work it's finish..... At last  ... on the air ... Spring  2015....smiley

 

 

( 9° image ..Telescopic pole basement diameter 10 cm and high 300 cm. assembled and then to go up in summer 2010  )

..Telescopic pole  high 15 meters to ground  for antennas : Windom home made size 41 meters and Dipole inverted V 40/80 with two coil home made size 26 meter and to up Diamomd 510 UHF VHF..

 

10° image... My station  … (. the last version  2016. )

..On the table there is my transceivers  a P.C. same microphones , the linear amplifier power, antenna turners , station monitor , many operating manual  e also a picture on P.C. “ He said: Hi !! Max…remember me!!  . HI HI . ”  my other hobby .I am very fond of fishing ..I like carp fishing .heart

***********************************************************************************

** I have my  TL922 Kenwood  since 1990 is linear amplifier  generous and powerful… I like it  !

**  I’m to become fond of and again  using now it  .. I drive with  300mA max.  +/-  30/40 watt  on continuous wave. In AFSK audio tone in digital mode RTTY,SSTV & SSB ( and only  max 30 watt  without amplifier on PSK31 …) AFSK digital mode MMTTY, MMSSTV, MMVARI “ beta”  can you see  web of Makoto Mori  JE1HHT  …  I use always only  Mode switch CW setting HV 2.2 kv also on SSB & SSTV ( Mode switch SSB HV 3.1 kv ) ..  I think  this setting  is very fine  to run at  optimum linearity  and inter modulation  distortion  ( IMD) is minimized  .

  **I using  always maximum  no more  +/-  300/400 watt  on delta loop 10 15 20 meter ..   RTTY  “AFSK” digital mode  & SSTV and in  phone  SSB.. and on 40/80 no more +/- 200/250 watt with dipole antenna  …  All impedance  50 Ώ...

**The  tuning in the first test absolutely  is necessary  a dummy load .. I use model MFJ-250 Versaload  with transformer oil .. power about  max . 1000 watt on  CW …   On MHz . 14.200 initial load setting with dummy load  Mode switch CW  HV  kv 2.2 = Increase the carrier control for sufficient drive to adjust the tuning ,with knob Processor  Out ..Quickly switch to IP and dip the Plate.. on FSK mode . Max.  650 mA =  +/- drive 100 watt input impedance  50 Ώ   output loading +/- 1000 watt.  and on SSB HV KV 3.2  loading  = Max. 650/750 mA  = +/-  1500/2000 watt. PeP.

**Two years ago I changed matched two tube 3500ZG, exact copy of the original tube Eimac 3500Z  ..  3500ZG graphite  anode  tube is best value for the price..  By RF PARTS Company  San Marcos  CA USA ..

**The first time can you see on  instruction  manual TL922 ..  ALC Adj.  control see  section  4.5. and  RF Adj. volt control  see section 4.6.

**Can you see on  instructions  manual  setting : SSB operation  section  4.3  ..

 CAUTION :::  DO NOT KEY THE LINEAR IN SSB MODE WITH FULL CW POWER …

     :::  NEVER CHANGE  THE BAND SWITCH WHILE TRANSMITTING…

** TL922 requires  an antenna  having a 50 to 75 Ώ impedance , rated for 2KW output  PeP power..

**My transceiver  Kenwood  TS950S Digital  with automatic tuning  (AT. TUNE)  without  external  matching box or antenna turner  ..  also I have  matching MT 1000 DX only 80 & 160 meter … 

**In  20 meter  on  delta  loop  3 band  10/15/20 meter

 MHz.  14.080 Digital mode AFSK ..  1.2 SWR  50Ώ  without AT.TUNE..

MHz.   14.200/300  SSB & SSTV .. 1.8/2.0 SWR  50Ώ   with  AT.TUNE..

 **In 15 meter  on  delta loop   …

MHz.   21.080 Digital mode  AFSK..   1.8 SWR  50Ώ  with AT.TUNE ..

MHz.   21.200/300  SSB & SSTV … 2.0/2.2 SWR  50Ώ  with AT.TUNE..

**In  10 meter  on delta loop …

MHz.  28.090   Digital mode  AFSK      MHz. 28.680 AFSK  SSTV  SSB  All with AT.TUNE 50 Ώ  …  

 

**My setting on AFSK  audio tone with integrated  Sound Card  Signalink  USB…  MHz. 14.230.. on SSTV mode … ( By Tigertronics  Grand Pass  Oregon USA ).. Is very fine for digital mode on AFSK audio tone : RTTY ,BPSK31 , HELL, SSTV and another  new  digital mode .

**Setting  Plate & Load  control on 20 meter  into dummy load … drive +/-  30 watt. on FSK mode switch on CW HV  kv  2.2  . Meter switch on RF 120/140 mA .. The  IP meter  plate current  +/- 300 mA  power  tube output  400 watt  on  continuous wave  …

** With this setting  the peak value increase on transmission  SSB ..  But .. I think it’s not necessary  more power  than you need…

 

** Sometimes … I work on SSB and using now Heil Sound Goldline GM5 dynamic studio microphone , polar pattern : cardiod . Range response of 50Hz – 16.000Hz  two position selects the wide & narrow.

** Tuning  in  40 meter  with dummy load  frequency    MHz  7.140.00-  

**Can you see in picture  above , setting  audio TS950S “ MIC-POWER “  for all modes on AFSK  audio tones … with microphone and sound card interface  SignaLink  USB … 

**I think that is all about the TL922 .. on the whole  I’m satisfied  to it …for me is a old friend ..we have had together many nice hours on air .... and I hope again in the future … hi hi ….

** Ok  fine  .. many thanks for your patience  and I’m sorry for some incomplete  information …the subjects  are large and necessity   more  details  …

 

                                                                    

... Thank you very muck for your vision and Good luck ! 73's

de"Mary" IK2QCF & "Max" IK2RZG.. smiley
