ARLB045 FCC Denies Expert Linears' Request for Waiver of 15 dB Rule, Petition
Pending

The FCC has denied a request by Expert Linears America LLC to waive Part
97.317(a)(2) of the Amateur Service rules limiting amplifier gain. Expert, of
Magnolia, Texas, distributes linears manufactured by SPE in Italy. Its waiver
request, filed in June, would have allowed Expert to import an amplifier
capable of exceeding the current 15 dB gain limitation as it awaits FCC action
on its April petition (RM-11767) to revise the same Amateur Service rules. That
 petition remains pending. Expert has asserted that there should be no gain
limitation on amplifiers sold or used in the Amateur Service. Most commenters
supported Expert's waiver request, but a couple of commenters - including
FlexRadio - demurred.

"In light of the conflicting comments regarding the desirability of eliminating
 the 15 dB limitation, we conclude that waiving the limitation at this stage of
 the rulemaking proceeding would prejudice the rulemaking proceeding and
prematurely dispose of commenters' concerns," the FCC said in denying the
waiver. "Moreover, we agree with FlexRadio that granting Expert's waiver
request while the rulemaking petition remains pending would provide an unfair
market advantage for one equipment model over other manufacturers' RF power
amplifiers that would still be limited by [the existing rules]."

The FCC said it would rather give full consideration to "the pending issues"
and apply the result of the rulemaking proceeding to all Amateur Radio Service
equipment. The Commission said rule waivers "generally" are not warranted
"merely to accommodate technical parameters that are based solely on
harmonization with the manufacturer's products available abroad."

The FCC said a minority of those commenting on the waiver request expressed
concern that eliminating the 15 dB limitation would lead to an overall increase
 in power levels, "including transmissions that intentionally or
unintentionally exceed the maximum power limit."

In its April rulemaking petition, Expert maintained that the 15 dB gain
limitation is an unneeded holdover from the days when amplifiers were less
efficient and the FCC was attempting to rein in the use of Amateur Service
amplifiers by Citizens Band operators.

Although the FCC had proposed in 2004 to delete the requirement that amplifiers
 be designed to use a minimum of 50 W of drive power - and subsequently did so
- it did not further discuss the 15 dB limit in the subsequent Report and Order
 in that proceeding.

Expert has pointed to its Model 1.3K FA amplifier as an example of a linear
"inherently capable of considerably more than 15 dB of amplification," which
would make it a suitable match for low-power transceivers now on the market.
