ANNOUNCING:  AVAILABILITY OF ALL VERSIONS OF THE RMU!

The RMU itself is very small and light as a feather, yet handles 1 kW of SSB/CW power.

It was co-developed be DJ0IP and DF4SA.

(The photo is intentionally fuzzy ... to confuse the copy cats.)

---------------------------------------------------------------------------------------------------

 

Spiderbeam now has RMU circuit boards in stock

for ALL FOUR versions of the RMU.

 

AVAILABILITY:  Beginning mid July 2019

 

We won't have time to test these until after the big European

HAM FEST in Friedrichshafen which is from June 21 to 23.

 

Here are the tentative Resonant Frequencies*:

  • Region 1 (RMU-R1):     3.670 MHz
  • Region 2 (RMU-R2):     3.800 MHz
  • 75m Bnd (RMU-75):     3.880 MHz
  • CW/Digi (RMU-CW):     3.570 MHz

We will check all of these in the field, AFTER the Friedrichshafen Ham Fest.

Until then, please regard these as approximate frequencies.

 

*These are the frequencies where minimum SWR occurs.

  The actual resonant frequency is slightly removed from the frequencies shown here.

  Production of the  807-HD  is going on NOW.

 

  • The 807-HD is currently in production, but . . .
  • Spiderbeam often has a backlog of orders from customers awaiting shipment.  The antennas are usually in stock, but when sold out, the estimated lead time is about 2 to 4 weeks.                   Contact Spiderbeam for details.

 

  • The 807-L is not currently shipping.  The construction is very complex and time consuming.  Spiderbeam does not currently have the manpower to build these. Rick is building about 1 per month and preference is given to customers who have planned EXpeditions.  Lead time can be up to 3 to 6 months.
    • Orders for non-expedition customers will be fulfilled "FIFO" (first in, first out).
    • Contact Spiderbeam for more info.

 

For our North American Users:

 

Special capacitors are currently on order which will enable us to build RMUs capable of setting:

  • the resonance for the 75m band (RMU-75) at about 3.880 MHz.  
  • the resonance for Region-2 (RMU-R2) at about 3.800 MHz.

The capacitors needed for doing this have arrived.  These are available upon special order and built to order.   Again the lack of manpower to build them is the only problem.
